Equity & Dilution Model

Understand how founder ownership changes as you raise money

What is a SAFE?

A SAFE (Simple Agreement for Future Equity) is not a loan and not shares yet. It's a promise that when a future funding round happens, the investor's money converts into shares at an agreed price. It lets you raise money now without having to officially price the company.

An investor puts in $100K on a SAFE today. No shares are issued yet. When a priced round happens (like an accelerator or Seed), the $100K converts into shares automatically.

What is a Valuation Cap?

The cap is the maximum valuation at which a SAFE converts into shares. It protects early investors — even if your company is worth $10M when it converts, they convert as if it's worth the cap. This means they get more shares for their money as a reward for investing early.

An investor has a $3.5M cap. If your company is worth $10M at the Seed round, they still convert as if it's $3.5M — a better price per share as their early-investor reward.

What is Dilution?

Every time you issue new shares (for investors, employees, etc.), the total number of shares grows — so each existing share represents a smaller slice of the pie. Your ownership % goes down. This isn't necessarily bad — a smaller % of a bigger, more valuable company can be worth far more.

You own 90% of a $1M company = $900K. After dilution you own 51% of a $40M company = $20.4M. The % dropped but the value exploded.

What is an ESOP Pool?

An Employee Stock Option Pool (ESOP) is equity set aside to hire and retain employees. Investors typically require a 10–15% pool to be created before their investment, which dilutes founders. Managing how fast you grant options matters a lot.

If you've used most of your 10% ESOP pool before Series A, investors will ask you to top it back up to ~12% before the round closes. Every point of that top-up comes from founders, not investors.

What is an MFN Clause?

Most Favoured Nation means an uncapped SAFE investor gets to convert at whatever the best terms are among future investors. If you have an uncapped SAFE with MFN and a later investor gets a $3.5M cap, the MFN investor automatically gets that same cap.

An angel invested $25K on an uncapped SAFE + MFN. A later investor comes in at a $3.5M cap. The angel now converts at $3.5M too — same as the later investor, as reward for going in first.

Post-Money vs Pre-Money SAFE

A post-money SAFE fixes your ownership % at the time of signing, regardless of who else invests later. $100K / $3.5M cap = 2.86% — locked. A pre-money SAFE means more investors reduce that investor's share. Post-money is cleaner and more predictable for both sides.

$100K on a $3.5M post-money SAFE = 2.86% ownership, locked at signing. Even if more angels pile in later, that investor stays at 2.86%.

What is a Friends & Family Round?

Often the very first outside money a startup raises — small checks from people who know the founders personally: parents, relatives, close friends, former colleagues. It's usually raised before any product or traction exists, purely on trust in the founders. Amounts are typically $10K–$150K total, often on SAFEs with low caps or sometimes uncapped with MFN.

A founder raises $50K from three family members on uncapped SAFEs with MFN clauses. When a pre-seed investor later comes in at a $3M cap, all three family members automatically get that same $3M cap — protecting their early trust with fair terms.

Friends & Family — What to Watch Out For

Keep it simple and fair. Use standard SAFEs (not handshake deals or custom contracts). Set expectations clearly: this is high-risk money that could be lost entirely. Avoid giving away too much equity early — low caps on large checks from family can cost founders dearly when those SAFEs convert. And never take money someone can't afford to lose.

A well-meaning uncle invests $100K on a $1M cap. That's 10% of the company locked in before any institutional investor. If a pre-seed VC later invests $100K at a $4M cap (2.5%), the uncle owns 4x more equity for the same amount — that early cap was set too low.
