Startup funding helps new businesses grow step by step. This guide explains each funding stage, from early ideas to big expansions.
You'll learn how to raise money, pitch to investors, and avoid common mistakes. It also covers other ways to get funding besides venture capital.
Whether you're just starting or planning your next big move, this guide will help you understand and prepare for the startup fundraising journey.
TL;DR: of Startup Funding Stages
Pre-Seed: Founders use personal funds or get help from friends and family to shape the idea.
Seed: Money is raised to build a product and test it in the market.
Series A: Focus on growing the user base and finding the right market fit.
Series B: Scale the business, hire more people, and expand into new markets.
Series C+: Big growth stage—may include acquisitions or getting ready for an IPO.
The Pre-Seed Funding stage is the earliest stage of the startup funding process. It is also known as the key ideation stage, as startups work on the idea to turn it into a tangible product or service.
Founders, Family, Angel Investors, Incubators, Startup Grants, Accelerators, Crowdfunding
$200,000 to $5,000,000
Equity Stakes, Convertible Notes, Revenue Sharing
DoorDash secured its pre-seed funding in 2013, receiving approximately $120,000 from Y Combinator, a prominent Silicon Valley startup accelerator. At this earliest funding stage, the founders—Tony Xu, Andy Fang, Stanley Tang, and Evan Moore used the investment primarily to validate their initial concept, develop a basic prototype, and test their restaurant delivery idea in Palo Alto, California.
The team manually delivered orders, analyzed market responses, and established preliminary relationships with local restaurants. This small, strategic investment allowed DoorDash to gain essential early traction, validate product-market fit, and build a foundation strong enough to attract subsequent funding rounds, ultimately positioning the company for substantial growth and long-term success.
Seed funding is the first official stage of financing, which usually occurs once the startup has developed the MVP. It allows businesses to switch from the MVP to a full-functional operation. The stage allows business to develop the MVP, get first-time users, and refine the business model.

$2,000,000 to $10,000,000
Acquisition (Mergers & Acquisitions - M&A), Initial Public Offering (IPO), Buyback by Founders or Company, Secondary Market Sales
Uber secured its seed funding in 2010, raising approximately $1.25 million from investors including First Round Capital, Lowercase Capital, and several angel investors such as Chris Sacca. At this early stage, Uber was essentially a small startup known as "UberCab," aiming to solve the inconvenience of hailing taxis by providing an on-demand, smartphone-based ride-hailing service.
The seed funding allowed Uber founders Travis Kalanick and Garrett Camp to further develop their initial app, expand operations beyond San Francisco, and validate the ride-hailing concept with users and drivers. This critical early funding provided Uber with the resources needed to prove the scalability and market demand of their business model, ultimately positioning the company for exponential growth and additional venture capital rounds.
Series A is the second round of financing for startups and also the first major massive institutional funding round. This round usually occurs once the company has developed a scalable business model, gained traction, and promises early stage revenue growth. ,
Venture Capital Firms (VCs), Corporate Venture Arms, Angel Syndicates, Late-Stage Seed Investors
$200,000 to $15,000,000
Series B Funding & Further Rounds, Acquisition (M&A), IPO
In November 2010, Airbnb successfully raised $7.2 million in Series A funding from investors including Sequoia Capital and Greylock Partners. At that time, Airbnb had validated its initial concept, secured early users, and achieved noticeable market traction. The Series A funds were strategically used to expand Airbnb's platform.
This amount enables it to expand to new markets beyond its initial cities, significantly scale up its team and technology infrastructure, and increase marketing efforts to drive user adoption globally. This round was critical in transforming Airbnb from a niche startup into a scalable business.
Series B funding is the third stage of financing for a startup. It is typically secured after achieving substantial growth, validating product-market fit, and establishing a clear path to profitability. At this funding stage, startups have aggressively dominated their market and strengthened their business model. Series B is focused on expanding operations, increasing revenue, and solidifying market leadership.
Growth-Stage VC Firms (Sequoia Capital, Andreessen Horowitz, Benchmark), Institutional Investors (Mutual funds, Hedge funds, Sovereign wealth funds), Corporate Venture Arms (Google Ventures, Salesforce Ventures), Late-Stage Investors (Tiger Global, SoftBank Vision Fund)
$10,000,000 to $30,000,000
Series C Funding & Further Rounds, Acquisition (M&A), IPO
Slack’s Series B funding round took place in October 2014, when the company raised $42.75 million. The round was led by investors such as Social Capital and Kleiner Perkins Caufield & Byers. At this stage, Slack had already gained significant traction as a popular communication platform among startups and tech companies.
Slack utilized the Series B funds primarily to accelerate product development, enhance platform reliability, expand its user base into larger enterprises, and build out marketing and sales teams. This funding round was crucial for Slack’s growth, positioning it to become one of the most widely adopted workplace collaboration tools globally.
Series C funding and beyond is the fourth stage of financing for a startup, typically raised after achieving strong market response, securing a clear industry position, and developing a strategic plan for continued expansion.
Late-Stage VC Firms(Sequoia Capital, SoftBank, Tiger Global), Private Equity Firms (KKR, Blackstone, Carlyle Group), Hedge Funds & Mutual Funds (T. Rowe Price, Fidelity, Wellington Management), Investment Banks & Corporate Investors(Goldman Sachs, Morgan Stanley, Google Ventures)
$30,00,000 to $100,000,000
Private Equity Buyout, Acquisition (M&A), IPO
In December 2014, Stripe raised $70 million in Series C funding led by Thrive Capital, with participation from Sequoia Capital, General Catalyst, Founders Fund, and Khosla Ventures. At this stage, Stripe was already established as a leading online payment processing solution for startups and businesses.
Stripe used the Series C funds to significantly enhance its technology platform, expand internationally, acquire key strategic partners, and attract larger enterprise customers. The round helped solidify Stripe’s market leadership and laid the groundwork for continued global expansion.
Raising capital is a crucial step in scaling a startup. It requires careful planning, financial discipline, and strategic investor alignment. Here's how to do it:
The first thing to identify is how much capital do you need.
An easy way to do that is by applying the Goldilocks Rule. The rule states that "Just the right amount" of something is best. This means that not too much and not too little. While determining the budget, you should also consider the following aspects to determine the capital needs:
Investors fund startups based on milestone achievements. So, you must identify the possible milestones you have achieved and the ones you want to achieve in future to determine the amount for the funds:
Runway refers to the duration for which the startup can run without running out of cash. It is ideal to ensure that funding lasts 12-18 months. You can calculate the runway by:
Runway (in months) = Total Cash / Monthly Burn Rate
For example, if the burn rate is $50K per month, raising $1.2M provides 24 months of runway.
Each funding round trades equity for capital, and over-dilution can weaken founder control. Typical dilution per round is 10-20% for Pre-Seed & Seed, 15-25% for Series A, and 10-20% for Series B. Founders should aim to retain at least 50-60% equity pre-Series A for long-term influence.
Investors prefer to invest in scalable businesses with a clear fundraising roadmap. Ensure that the fundraising provides enough capital to reach the next round without premature dilution. In order to do, startups should assess expected revenue growth, scalability of unit economics, and timing of the next raise. This helps to balance both capital efficiency and business expansion.
Research similar startups and market trends to validate fundraising targets. Investors often compare peer funding rounds, valuations, and capital efficiency to assess whether a startup is raising an appropriate amount or not. Platforms like Crunchbase, AngelList, and PitchBook can provide insights into industry norms.
A pitch deck is a visual presentation that startups utilise to convey their business idea, market opportunities, and investment potential to investors. Therefore, it is the first impression your business presents to investors.
It must be concise and compelling while effectively communicating the company’s vision, traction, and financial projections. Your pitch deck must highlight the following things:
Next, is to understand the term sheet. A term sheet is a document that outlines the basic terms of an investment deal between a startup and an investor. It serves as a precursor to more detailed and legally binding agreements.
Note:
Not Binding: Even though a term sheet outlines all these details, it's not a final contract. It's more like a proposal that both parties agree to before they create a formal, legally binding contract.
Serves as a Pre-cursor: A term sheet is the first step before creating more detailed and legally binding agreements. It helps both parties agree on the basics before they finalise everything in a formal contract.
The major clauses in the term sheet are as follows:
This section explains how much your company is worth and how much ownership the investor will get.
Pre-Money Valuation
Equity Stake
These rules explain how much control investors have and how they can get their money back later.
Drag-Along & Tag-Along Rights
Right of First Refusal (ROFR)
Lock-In Periods
Exit Options
These rights protect investors and give them a say in big decisions.
Board Rights & Voting Control
Liquidation Preferences
Founder Vesting
Anti-Dilution Protection
Weighted Average
Full Ratchet
No-Shop Clause
Information Rights
Before approaching investors, ensure you document the legal and financial structures of the startup. Investors conduct extensive due diligence, and having everything in order builds confidence and speeds up deal closure.
You should consider the following:
Outlines ownership distribution, detailing founder, investor, and employee equity. Helps track dilution across funding rounds and ensures transparency in future investments.
Defines voting rights, equity distribution, decision-making powers, and exit strategies for all stakeholders. Ensures smooth governance and minimises conflicts.
Includes financial statements (P&L, balance sheets, tax filings), intellectual property (IP) ownership records, contracts, and operational agreements. Investors will scrutinise these to assess business stability.
Ensure the startup meets all the legal requirements, industry regulations, and corporate governance standards. Covers licenses, trademarks, data protection policies, employee agreements, and tax compliance to prevent legal risks.
Getting the funding is not just about securing the required investment but also about closing the deal at favorable terms. Favourable terms help maintain control and long-term scalability. Here’s how you can manage the negotiations with the investors:
VCs invest in startups based on key growth indicators, team strength, and market potential. So, understanding what VCs prioritise can help founders position their companies effectively. They consider the following:
Maintaining leverage in negotiations ensures better deal terms, fair valuation, and strategic investor alignment. Here’s how founders can strengthen their position:
One of the most effective ways to increase bargaining power is to have multiple investors interested in your startup and not accept the first offer you get. When investors compete for a deal, they are more likely to offer better valuations, favorable terms, and added strategic value.
Try to create a sense of urgency by leveraging FOMO (Fear of Missing Out). It helps push investors to move faster and offer improved terms. The best deals happen when investors feel they must act quickly to secure their stake.
For instance, when Clubhouse was raising its Series A funding, the founders, Paul Davison and Rohan Seth, skillfully generated intense investor competition by attracting multiple prominent venture capital firms simultaneously, including Andreessen Horowitz, Benchmark, and others.
They leveraged the rapidly growing popularity of the app and created urgency among investors through exclusivity and invitation-only access, amplifying investors’ Fear of Missing Out (FOMO).
As a result, Andreessen Horowitz acted decisively, quickly committing $10 million at a $100 million valuation, securing the deal and effectively preventing rival investors from having a chance to counter. This strategic move greatly strengthened Clubhouse’s negotiating leverage, resulting in highly favorable terms and valuation.
Investors love to take their time, but dragging out negotiations can weaken your position and burn resources. To prevent this, founders must establish a clear fundraising timeline with defined deadlines for term sheets and final commitments.
You should also signal to investors that the company is moving forward, with or without them. Moreover, rather than waiting for funding, startups must leverage the ongoing traction to strengthen their position and become more attractive to investors.
For instance, when productivity software company Notion raised funding rounds, founder Ivan Zhao deliberately set short, definitive timelines for investors to provide term sheets and commit capital.
By clearly communicating that Notion was prepared to continue its rapid product growth with or without immediate investor support, Zhao prevented prolonged negotiations. Investors, recognizing Notion’s momentum and potential, accelerated their decision-making processes.
Consequently, Notion swiftly secured $50 million from Index Ventures at a favorable $2 billion valuation without lengthy negotiations diluting its leverage.
One of the biggest mistakes a founder can make in negotiations is being uncertain about their financials. Investors often challenge founders about numbers, projections, and growth potential. So, it is crucial to have a well-researched valuation strategy based on market benchmarks, revenue projection, and industry comparisons.
Founders should also understand equity dilution and how each funding round impacts ownership percentages. While being realistic yet confident about valuation is necessary, founders should avoid overvaluing or undervaluing their company, as both can weaken negotiation power.
For instance, Zoom raised its early-stage funding, and founder Eric Yuan displayed exceptional clarity and precision regarding Zoom’s valuation and financial performance. Yuan extensively benchmarked Zoom against other SaaS and communication platforms in the industry.
They also clearly articulated how Zoom’s growth metrics, revenue trajectory, and customer retention rates justified its proposed valuation. He confidently addressed investors' challenges by showing detailed financial projections and demonstrating deep knowledge of equity dilution and ownership implications at every funding stage.
Yuan’s preparation reassured investors like Emergence Capital, ultimately helping Zoom secure its $30 million Series C round at a strong valuation while maintaining optimal founder and employee ownership levels.
Funding is important, but not all investors provide equal value. Instead of focusing solely on capital, founders should prioritise investors who offer industry expertise, valuable networks, and strategic resources to accelerate growth.
Look for investors who can provide mentorship, introductions, and operational support.
Moreover, founders should choose investors who believe in their company’s mission and roadmap. A slightly lower valuation from an investor who adds strategic value can be more advantageous than a higher valuation from one who offers no additional support.
For instance, During its Series A, DoorDash founder Tony Xu chose Sequoia Capital over investors offering higher valuations because Sequoia provided critical strategic support beyond capital. Specifically, Sequoia partner Alfred Lin’s operational expertise and extensive network significantly accelerated DoorDash’s growth, making it the leader in the food delivery market and paving the way to a successful IPO.
Equity dilution occurs when a company issues new shares, reducing the ownership percentage of existing shareholders. This is a common outcome during fundraising rounds, employee stock option plans (ESOPs), or conversions of preferred shares into common shares.
Typical Dilution Percentages by Funding Round
It is also essential to track the cap table. A Cap Table (Capitalisation Table) is a document that tracks who owns what percentage of the company. Keeping a clean, updated cap table prevents unnecessary dilution and helps forecast ownership distribution in future rounds. Here is an example to understand the same:
A company has a Pre-Money Valuation of $12M and a Post-Money Valuation of $16M.
Before Funding Round
After Funding Round ($4 Million Raised)
Many startups fail not because of a bad idea but due to poor fundraising strategies, mismanagement of capital, and misaligned investor relationships. Learning from these failures can help founders understand the fundraising process effectively and avoid costly mistakes. They are as follows:
Many founders miscalculate how much funding they need, leading to either underfunding or overfunding. Raising too little means the company won’t reach critical milestones, forcing another funding round sooner than expected. This puts the startup in a weaker negotiating position for future rounds.
Raising too much results in excessive dilution, unnecessary spending, and pressure to justify an inflated valuation in the next round. Startups that fail to sustain aggressive growth after overfunding often struggle to raise later rounds.
For instance, Quibi, a short-form video streaming platform, raised an astounding $1.75 billion in funding but struggled due to a lack of product-market fit. Despite its high-profile launch and investment in premium content, the platform failed to attract and retain users, as its paid subscription model faced stiff competition from free alternatives like TikTok and YouTube.
Solution: Calculate a 12-18 month runway, ensuring enough capital to hit key milestones before the next round. Fundraise based on realistic financial forecasts, not just how much investors are willing to give.
Not all investors are the right fit. Some can push for unrealistic growth, demand excessive control, or lack industry expertise, creating long-term conflicts. Certain investors micromanage operations, making it difficult for founders to run the company independently. Founders who don’t research their investors may end up with misaligned partners who force unwanted exits.
For instance, WeWork’s decision to heavily partner with investor SoftBank turned problematic, as SoftBank pushed aggressively for rapid growth, high valuations, and unrealistic expansion targets. Founder Adam Neumann faced intense pressure, lost strategic independence, and ultimately was forced out, leading to a disastrous IPO attempt and substantial damage to WeWork’s reputation.
Solution: Choose investors who provide mentorship, strategic connections, and long-term alignment, not just money. Conduct investor due diligence by speaking with their previous portfolio companies before committing.
Many startups lack proper financial records and legal structures before fundraising, making them look disorganized and unreliable. Unclear cap tables create confusion about ownership distribution. Moreover, incomplete financials raise red flags for investors about cash flow and sustainability.
For instance, Cryptocurrency exchange FTX collapsed dramatically due to poor financial and legal preparation, including incomplete financial records, unclear asset management, and insufficient legal structures. These fundamental weaknesses raised significant investor red flags, damaged credibility, and ultimately led to FTX’s bankruptcy and massive financial losses.
Solution: Have structured data with all necessary legal and financial documents such as financial statements (P&L, burn rate, revenue growth), cap table (ownership breakdown across investors and founders), Tax filings, contracts, and IP documents
Some founders focus too much on data and fail to present a compelling story that excites investors. It is essential to understand that investors don’t just back businesses. They only invest in startups with vision and execution power. Moreover, overloading investors with technical jargon and excessive slides reduces interest.
For instance, Canva founder Melanie Perkins initially faced multiple rejections because her early pitches overemphasised product features and complex technical details and lacked emotional connection.
After simplifying her pitch into a powerful narrative, she was able to effectively captivate investors. They later secured funding from influential VCs, including Matrix Partners and Sequoia Capital. Perkins’ refined storytelling clearly conveyed Canva’s vision, dramatically increasing investor interest and enthusiasm.
Solution: Craft a clear, concise, and engaging pitch deck that tells a compelling story with solid data.
While venture capital (VC) funding is a popular route, it’s not the only way for startups to raise capital. Founders can explore alternative fundraising methods to secure funding without giving up too much equity or control. Below are some viable financing options:
Revenue-based financing (RBF) is an alternative funding model where startups receive capital upfront and repay it as a percentage of their revenue over time. RBF does not require giving up ownership in the company. Instead, repayments are tied to revenue performance, meaning payments fluctuate based on how well the business is doing.
Clearco, Pipe, Lighter Capital, Uncapped
Crowdfunding allows startups to raise money from a large number of people (individual investors, early adopters, and supporters) through online platforms.
It’s an effective way to validate product-market fit, gain early traction, and secure funding without relying on institutional investors. The types of crowdfunding are as follows:
Kickstarter, Indiegogo, Republic, Wefunder
Convertible notes are a flexible fundraising option that allows startups to raise capital quickly without setting an immediate valuation. Instead of receiving equity upfront, investors provide funding as a loan that converts into equity at a later funding round (typically Series A or another priced round).
This method is particularly useful for early-stage startups that need fast funding but don’t have a solid valuation yet.
SAFE is a founder-friendly fundraising option that allows startups to raise capital without issuing immediate equity or setting a valuation. It is a simpler alternative to convertible notes, as it doesn’t carry interest or a maturity date. Instead, the investor’s funds convert into equity at a future priced funding round (typically Series A).
Y Combinator, AngelList, Early-Stage VCs, and Startup Accelerators
Angel investors are high-net-worth individuals who fund startups in exchange for equity or convertible notes. They are often more flexible than VC firms and may provide mentorship in addition to capital.
AngelList, Tech Coast Angels, Golden Seeds, 500 Global, SeedInvest
Here are some of the common fundraising mistakes that can impact their growth, valuation, and control. Here’s how to avoid the most common pitfalls:
One of the biggest red flags for investors is a lack of a clear funding strategy. Many startups focus on raising money without a solid plan for how the capital will be allocated. This often leads to wasteful spending, uncontrolled hiring, or investing in the wrong growth channels, causing startups to burn through cash without meaningful progress.
Investors want to see a data-backed roadmap that clearly outlines how the funds will drive key milestones such as product development, hiring, or market expansion. Without this clarity, founders risk losing investor confidence and struggling to raise future rounds.
For example, Online checkout startup Fast raised over $120 million without a clear, structured plan for capital allocation. Funds were quickly spent on aggressive marketing, rapid hiring, and flashy branding rather than sustainable product development or customer acquisition. As a result, Fast burned through its cash reserves without clear business milestones, eventually collapsing due to unsustainable spending and a lack of investor confidence.
Finding the right valuation is essential. Setting it too high can make future fundraising difficult, while setting it too low can lead to excessive dilution and loss of control. Overvaluation often happens when startups inflate their market potential or revenue projections, leading investors to expect unrealistic growth rates.
If the startup fails to meet these high expectations, it may have to raise a down round, which can hurt its reputation and investor confidence. Conversely, undervaluing the company might make it easier to attract investors but can result in giving away too much equity too early, leaving little room for future funding rounds.
For instance, Swedish fintech startup Klarna was valued at a peak of $45.6 billion in its 2021 funding round, driven by optimistic market conditions and overly ambitious growth projections. When the economic climate shifted in 2022, Klarna was unable to sustain such inflated expectations.
This forced them to raise a subsequent round at a drastically reduced valuation of $6.7 billion. This dramatic down-round severely impacted investor confidence, diluted early shareholders' equity, and weakened Klarna's negotiating position for future fundraising rounds.
Many founders fail to recognise that investors aren’t just providing capital but are investing in long-term returns. Every investor has different expectations, and failing to align with them can create conflicts over company direction, growth strategy, and exit plans.
Some VCs prioritise rapid scaling and aggressive expansion, while others prefer steady, sustainable growth. If a startup takes funding from investors with mismatched goals, they may face pressure to scale too quickly or be forced into an exit before they’re ready.
For instance, Yahoo acquired social blogging platform Tumblr for $1.1 billion in 2013, Tumblr’s community-driven model heavily conflicted with Yahoo investors’ expectations of rapid monetization and revenue growth.
Yahoo pushed for aggressive advertising strategies, dramatically altering Tumblr’s user experience. This misalignment with the expectations and interests of Yahoo’s shareholders and management caused significant conflicts.
It also harmed user engagement and ultimately decreased Tumblr’s user base and valuation. Yahoo eventually sold Tumblr to Automattic (owner of WordPress) for just a fraction of its original purchase price.
Many startups focus only on the current funding round without planning how it will affect future capital needs. This short-term thinking often results in running out of cash before achieving critical milestones.
This also forces startups to fundraise under pressure, which can lead to bad investor terms, down rounds, or excessive dilution. A well-planned fundraising strategy should not just address immediate financial needs but also set up a clear pathway for future rounds.
For instance, Used-car marketplace startup Beepi successfully raised about $150 million in funding. However, the founders did not strategically plan for subsequent funding rounds. They overspent on marketing, rapid team expansion, and ambitious growth initiatives without reaching sustainable milestones or profitability.
When the company needed more capital, investors were wary of poor financial management, unsustainable burn rates, and limited traction. Consequently, Beepi was unable to raise additional funds, abruptly shut down, and became an infamous example of startups failing to plan strategically for future financing rounds.
FURTHER READING:
Raising capital is crucial but not one-size-fits-all. Founders should assess their capital needs and explore alternatives like bootstrapping, grants, or revenue-based financing instead of relying solely on VC funding.
Moreover, before approaching investors, investors should understand that key financial metrics like traction, revenue growth, and burn rate are essential. Structured data room with financials and legal documents boosts credibility.
It is also essential to understand that fundraising is an ongoing process. Startups should plan 12-18 months ahead for the next round by managing burn rate, hitting milestones, and building investor relationships. Ultimately, fundraising is not just about money, rather, it’s about finding the right partners to fuel long-term success.
