What is the key difference between Pre-Money and Post-Money Valuation?

Pre-money is the company's valuation before receiving new cash. Post-money equals pre-money plus the incoming investment cash.

How is investor ownership percentage calculated?

Investor Ownership (%) = (New Investment Amount / Post-Money Valuation) × 100. For example, a $2M investment on an $8M pre-money ($10M post) equals 20% ownership.

Why do founders prefer higher pre-money valuations?

A higher pre-money valuation means the founder sells a smaller percentage of company equity to raise the same amount of capital, suffering less dilution.

How does an Employee Stock Option Pool (ESOP) affect pre-money valuation?

VC term sheets often require a 10% to 15% unallocated option pool created on a pre-money basis, which dilutes existing founders before the investor's cash arrives.

What is the difference between a priced equity round and a SAFE note?

A priced round sets an explicit post-money valuation and issues shares immediately. A SAFE (Simple Agreement for Future Equity) converts into equity during a future priced round.

How are new shares issued in a venture financing round?

New shares = Investment Amount / Price Per Share. The existing shares remain with founders, and newly minted shares are assigned to incoming investors.
