Term sheet basics: valuation and dilution

Pre-money, post-money, dilution and option pools, with a worked example, plus the other terms that matter.

A term sheet is a short, mostly non-binding summary of an investment. Once signed, lawyers turn it into the final documents. Most of the important negotiation happens at the term sheet, so understand every line.

Pre-money and post-money

  • Pre-money valuation: what the company is worth before the new money.
  • Post-money valuation: pre-money + the investment.
  • Investor ownership = investment ÷ post-money valuation.

Worked example

  1. 1
    Starting pointTwo founders own 4,000,000 shares together (2,000,000 each, 50/50).
  2. 2
    The offerAn investor puts in 1,000,000 € at a 4,000,000 € pre-money valuation. Post-money = 5,000,000 €.
  3. 3
    Share price4,000,000 € ÷ 4,000,000 shares = 1 € per share. The investor gets 1,000,000 new shares.
  4. 4
    Ownership afterTotal 5,000,000 shares. Investor 20%, each founder 40%. The founders were diluted from 100% to 80%, but own 80% of a company worth more.

The option pool

Investors often ask for an option pool for future employees, for example 10% of the company after the round, created before their money comes in. That means the founders carry all of it.

Same deal with a 10% post-money pool created in the pre-money: investor 20%, pool 10%, founders 70% (35% each). The headline valuation is the same, but the founders own less. Negotiate the pool size based on a real hiring plan.

Other terms to understand

  • Liquidation preference: who gets paid first if the company is sold. '1× non-participating' is the founder-friendly standard.
  • Board composition: who sits on the board and who appoints them.
  • Protective provisions: decisions that need investor approval.
  • Anti-dilution: protection for investors if a later round is at a lower price. 'Broad-based weighted average' is common and fair.
  • Pro rata rights: the investor's right to invest in future rounds.
  • Founder vesting: investors may ask founders to re-vest some shares.
  • Exclusivity: a period in which you can't negotiate with other investors.
Always have an experienced startup lawyer review a term sheet before you sign. A good one costs far less than a bad clause.
