Your startup concept featuring an AI-based pizza robot capable of producing ultimate Neapolitan pizzas emerges as your idea. Sounds awesome, right?
The sole hurdle facing your brilliant idea is financial investment to construct the product along with advertising it and expanding your business operations.
Business funding becomes essential at this particular point. The funding path knowledge forms a critical foundation for starting and growing a business through an IPO acquisition. To start the discussion we will examine the sequence of budgeting stages which launches with personal savings before attracting venture capitalists (VCs) and private equity investors.
Why Do Startups Raise Funds?
Startups undertake fundraising activities for professional reasons beyond mere money acquisition. They need funding for:
✔ Building the Product – Transforming an idea into a real product.
✔ Hiring a Team – Engineers, marketers, and salespeople don’t come cheap!
✔ Marketing & Customer Acquisition – How will people know your product exists?
✔ Scaling the Business – Expanding into new markets or launching new features.
✔ Beating the Competition – Staying ahead in the game.
Now, let’s explore how startups raise funds at each stage.
Startup Funding Stages
1) Friends & Family Round (Pre-Seed) – "The Trust Me Stage"
Stage: Idea or early prototype
Who invests: Friends, family, and personal savings
Amount Raised: $10,000 - $100,000
Risk Level: Extreme
During this time individuals share their brilliant ideas with their parents.
Entrepreneurs typically launch their concept by obtaining investment from their closest relatives or funding it with their funds. The investors in this stage depend on you rather than fast returns since they believe in your potential.
🔹Example: Jeff Bezos received a total of $245,573 from his parents when they invested in Amazon at its initial stage.
💡Pro Tip: If you raise money from family, keep things professional—draft legal agreements to avoid future disputes!
2) Angel Investors & Pre-Seed Funding – "The Believers"
Stage: Founders move to MVP when the minimum viable product reaches readiness.
Who invests: Angel investors, startup incubators, accelerators
Amount Raised: $100,000 - $1M
Risk Level: Very High
Well-to-do investors known as angel investors put their funds toward initial-stage startup businesses. Now you gain your very first meaningful support from outside investors.
🔹Example: The first funding of $200,000 that Uber received came from angel investor Garrett Camp.
💡Pro Tip: By joining a program like Y Combinator you will receive capital funding together with valuable mentorship and useful business connections.
3) Seed Funding – "The Let’s Get Serious Round"
Stage: The funding phase occurs at the beginning of revenue generation when user numbers increase while testing product-market compatibility.
Who invests: Angel investors, micro-VCs, and crowdfunding platforms.
Amount Raised: $1M - $5M
Risk Level: High
At this stage, businesses enter a serious milestone. Investors base their funding decisions on how much you can develop before they approve the money. Funding during this stage helps companies recruit additional employees to improve their products along with intensive market promotion efforts.
🔹Example: The seed funding round of Airbnb secured $600,000 even though venture capitalists refused to invest at this stage.
Venture Capital (VC) Rounds – The Big Leagues
4) Series A – "The Scaling Stage"
Stage: It combines a robust user base along with increasing revenue and verified business processes.
Who invests: Venture capital firms
Amount Raised: $5M - $15M
Valuation: $10M - $30M
Risk Level: Medium
During this phase, investors anticipate to see a solid growth path toward generating profits. Business expansion becomes the priority while the company recruits new staff to enhance its operational structure.
🔹Example: Instagram raised $7M in Series A before being acquired by Facebook for $1B.
💡Investor Expectation: Investors from VC firms expect a 10-fold return on their funds within the 5 to 7-year time period.
5) Series B – “The Rapid Growth Phase”
Stage: During the explosive growth phase the business expands its operations to establish positions in newly developed markets.
Who invests: Larger VC firms, institutional investors
Amount Raised: $20M - $50M
Risk Level: Medium
Your startup no longer operates as a scrappy newcomer as you enter competition against industry leaders. Big revenue targets and efficient customer acquisition methods are expected by those investing in businesses.
🔹 Example: Spotify used Series B funding to expand into global markets.
💡 Growth Hack: Startups often use this round to acquire smaller competitors.
6) Series C – “Dominating the Market Stage”
Stage: Expanding internationally, acquiring companies
Who invests: The investment stage includes capital from hedge funds along with corporate capital and private equity businesses.
Amount Raised: $50M - $100M+
Risk Level: Low
Your startup controls the market share but continues to need growth expansion. The future consideration of corporate IPO at this expansion stage is common practice for certain enterprises.
🔹 Example: SpaceX raised over $1B in Series C funding to develop reusable rockets.
7) Series D & E – “Pre-IPO or Last-Resort Capital”
Stage: Prepping for IPO OR struggling to stay afloat
Who invests: The investors during this phase include PE firms together with sovereign wealth funds alongside late-stage VCs.
Amount Raised: $100M - $500M+
Your startup exists at either one of two stages following its initial development. Startups that reach the unicorn status at $1B+ prepare themselves for their initial public offering. The company reaches a crucial financial crisis and requires more funds for survival.
🔹 Example: WeWork obtained billions from late-round funding yet failed to survive until its IPO was ready.
💡 Key Lesson: Not all startups need Series D/E. Some companies, like Mailchimp, bootstrap never raise VC money!
Private Equity Growth & IPO – The Final Stages
8) Private Equity (Growth Funding) – “The Billion-Dollar Bet”
The startup has expanded to become an enormous business at this phase. Private equity firms dedicate investments to high-growth mature startups before companies pursue an IPO route.
🔹Example: Byju received funding from private equity investors so they could launch global expansion operations.
9) IPO (Initial Public Offering) – “The Big Payday”
A startup can achieve public status after conducting an IPO which provides investors the chance to buy stock through the stock market.
🔹Example: Facebook attracted $16 billion through its IPO which became one of the largest technology IPOs in history.
💡 Why Go Public? IPOs give investors and founders access to large market liquidity while subjecting them to enhanced regulatory oversight.
