Startup Fundraising
Should you raise money or bootstrap? Angels vs VCs, seed rounds vs Series A, term sheets and cap tables — everything founders need to know about funding, explained without the jargon.
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?"
✗ Without AI
- ✗You keep 100% ownership
- ✗Grow at your own pace
- ✗Profitable from early on (or die)
- ✗Full control over decisions
- ✗Limited by your revenue and savings
- ✗Best for: services, SaaS, niche products
✓ With AI
- ✓You sell ownership for cash
- ✓Pressure to grow fast (10x in 18 months)
- ✓Can lose money for years chasing growth
- ✓Investors get board seats and veto rights
- ✓Limited by investor patience, not revenue
- ✓Best for: winner-take-all markets, network effects, deep tech
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.
Personal savings, friends & family, small angel checks. You have an idea and maybe a prototype.
Angel investors, seed funds, accelerators (YC, Techstars). You have early traction — some users, maybe revenue.
Venture capital firms. You have product-market fit and repeatable growth. VCs want proof, not promises.
Growth-stage VCs. You are scaling fast and need capital to dominate your market.
Late-stage VCs, private equity, hedge funds. You are preparing for IPO or major expansion.
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
| Investor type | Typical check size | What they want | What they offer beyond money |
|---|---|---|---|
| Friends & family | $5K - $50K | To help you succeed | Emotional support (and holiday awkwardness if it fails) |
| Angel investors | $25K - $250K | 10-50x return in 5-10 years | Industry expertise, introductions, mentorship |
| Accelerators (YC, Techstars) | $125K - $500K | Equity (typically 7-10%) | Curriculum, mentor network, demo day, alumni network |
| Seed funds | $500K - $2M | Early ownership in breakout companies | Portfolio support, follow-on funding |
| VCs (Series A+) | $3M - $50M+ | Fund-returning outcomes (100x) | Board governance, operational support, hiring help |
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)
Approximate median US pre-money valuations by stage, 2024 (PitchBook data — ranges vary widely by market and sector).
Calculate the Ownership
50 XPCap 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:
| Shareholder | Shares | Ownership |
|---|---|---|
| Founder A | 4,000,000 | 40% |
| Founder B | 4,000,000 | 40% |
| Seed investor | 1,500,000 | 15% |
| Employee option pool | 500,000 | 5% |
| Total | 10,000,000 | 100% |
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:
| Term | What it means | What to watch for |
|---|---|---|
| Valuation | Pre-money and post-money | Is it fair for your stage and traction? |
| Liquidation preference | Who gets paid first if the company sells | 1x is standard; 2x+ is investor-friendly and can hurt founders |
| Board seats | Who controls the board of directors | Keep founder majority through seed and Series A |
| Anti-dilution | Protects investors if the next round is at a lower valuation | Broad-based weighted average is standard; full ratchet is aggressive |
| Vesting | How founders earn their shares over time | 4-year vesting with 1-year cliff is standard for everyone, including founders |
| Pro-rata rights | Investor's right to invest in future rounds | Standard; not a big deal |
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.
Red Flag or Standard?
25 XPWhen 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
Should They Raise?
25 XPKey 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
