Startup Fundraising

The founders who said no to $3 billion

In 2014, Jan Koum and Brian Acton sold WhatsApp to Facebook for $19 billion. But what most people don't know is the backstory: in 2009, Brian Acton applied for jobs at both Facebook and Twitter. He was rejected by both.

He tweeted: "Facebook turned me down. It was a great opportunity to connect with some fantastic people. Looking forward to life's next adventure."

That next adventure was WhatsApp. Koum and Acton bootstrapped it with $250,000 of Koum's personal savings. They took one round of outside funding — $8 million from Sequoia Capital in 2011 — and then raised $50 million more from Sequoia in 2013. That's it. Two rounds from one investor.

Meanwhile, their competitors raised hundreds of millions from dozens of investors, hired massive teams, and burned cash on user acquisition. WhatsApp stayed lean: 55 employees serving 450 million users at the time of the Facebook acquisition.

The lesson isn't "never raise money." It's that how you fund your startup shapes everything — your speed, your control, your culture, and your exit options.

Bootstrapping vs. raising money

The first decision isn't "who should I raise from?" It's "should I raise at all?"

Neither is better in absolute terms. The right choice depends on your market, your ambitions, and your risk tolerance.

Bootstrap when:

• Your market doesn't require a land grab
• You can get to revenue quickly
• You value independence over speed
• Your startup costs are low

Raise when:

• Speed is a competitive advantage (network effects, marketplaces)
• You need significant upfront capital (hardware, biotech, infrastructure)
• The market is winner-take-all and being second means losing
• You want to grow faster than revenue allows

The funding ladder: from friends to IPO

Startup funding happens in stages. Each stage has different investors, different amounts, and different expectations.

Most startups in this course will deal with pre-seed and seed stages. Series A and beyond are for companies that have already found product-market fit.

Types of investors

There Are No Dumb Questions

"What's the difference between an angel investor and a VC?"

An angel invests their own money. A VC invests other people's money (from a fund raised from limited partners — pension funds, endowments, wealthy individuals). This matters because VCs have obligations to their LPs — they need big returns, so they push for aggressive growth and large outcomes. Angels can be more patient and flexible.

"Is Y Combinator worth it? They take 7% of my company."

YC invests $500,000 (as of 2024) for ~7% equity. But the real value is the network — YC companies raise follow-on funding at higher valuations, get introductions to investors and customers, and join a community of 5,000+ alumni. For most early-stage companies, the network effect alone justifies the dilution.

How startup valuation works

Valuation is the number everyone obsesses over — and the number most founders misunderstand.

Pre-money valuation = what your company is worth before the investment. Post-money valuation = pre-money + the investment amount.

Example: An investor puts in $1M at a $4M pre-money valuation.

• Post-money = $4M + $1M = $5M
• The investor owns $1M / $5M = 20% of the company

At the seed stage, valuation is more art than science. There's no revenue multiple or DCF model. It's based on:

• Team strength
• Market size
• Traction so far
• Comparable deals (what similar companies raised at similar stages)
• Supply and demand (hot market = higher valuations)

Cap tables: who owns what

A capitalisation table (cap table) is a spreadsheet that tracks every owner's percentage of the company. It starts simple and gets complicated with every round.

Here's a simplified cap table after a seed round:

Every time you raise money, everyone's percentage goes down (dilution). This is normal and expected. Owning 40% of a $100M company is better than owning 100% of a $1M company.

Term sheets: what to actually read

When an investor wants to fund you, they send a term sheet — a document outlining the deal terms. Most of it is negotiable. Here are the terms that matter most:

There Are No Dumb Questions

"What's a SAFE and how is it different from a term sheet?"

A SAFE (Simple Agreement for Future Equity), created by Y Combinator, is a simpler alternative to traditional seed-stage funding documents. Instead of negotiating a full term sheet, the investor gives you money in exchange for the right to receive equity in your next priced round. SAFEs are faster, cheaper (less legal fees), and have become the standard for pre-seed and seed deals in the US.

"Should I use a lawyer?"

Always. A startup lawyer will cost $3,000-$10,000 for a fundraising round but will save you from terms that could cost you millions later. Never sign a term sheet without legal review. Many law firms defer fees for early-stage startups.

When NOT to raise

Raising money feels like a milestone — but it's actually a tool. And like any tool, it's wrong for some jobs.

Don't raise if:

• You can reach profitability within 6-12 months on your own
• You haven't validated the idea yet (investors' money won't fix a bad idea, it'll just delay the failure)
• You're raising to pay yourself a salary before you have product-market fit
• Your market is a $10M niche — VCs need $1B+ outcomes to make their fund math work
• You don't want to give up control or answer to a board

Do raise if:

• Speed is genuinely a competitive advantage
• You need capital to build something before you can generate revenue
• You've validated demand and know exactly what the money will accelerate
• You're okay with the trade-offs: dilution, reporting, loss of full autonomy

Key takeaways

• Bootstrapping vs. VC isn't better/worse — it's a strategic choice based on your market, speed needs, and ambitions
• Funding comes in stages: pre-seed → seed → Series A → B → C → IPO. Most startups only deal with pre-seed and seed
• Valuation = pre-money + investment = post-money. Every round dilutes existing owners
• Cap tables track who owns what — watch your dilution and aim to keep founder ownership above 50% through Series A
• Term sheets are negotiable — focus on valuation, liquidation preferences, board control, and vesting
• SAFEs are the standard for early-stage seed deals — simpler and cheaper than priced rounds
• Don't raise just because you can — raise when capital genuinely accelerates your path to product-market fit
