Why this matters
The term sheet decides who owns what, who controls what, and what you actually take home at exit — for the life of the company. Founders who negotiate only the valuation give the difference back through terms they didn't understand.
What "done" looks like
- You can explain every clause: pre/post-money, option pool, liquidation preference, pro rata, board seats
- Dilution modeled, including the new option pool
- A startup lawyer (not a generalist) has reviewed it
- You know which terms are market-standard and which are off-market
How to do it
- Learn the vocabulary: post-money valuation, 1x non-participating liquidation preference (standard) versus participating (off-market), the option-pool shuffle, board composition.
- Model the dilution yourself — a pool created pre-money comes out of your side.
- Compare against public standards: YC's SAFE for early rounds, NVCA model documents for priced rounds.
- Hire a startup lawyer — flat-fee seed reviews are normal.
- Negotiate the few terms that matter — valuation, pool size, preference, board — and concede the boilerplate.
- Weigh control terms as heavily as price — vetoes and board seats outlast valuations.
Common mistakes
- Maximizing headline valuation while accepting a participating preference or an oversized pool
- Using the family lawyer who did your lease
- Treating the signed term sheet as a closed deal — most of it is non-binding until definitive documents
Real-world examples
- YC's SAFE, written by Carolynn Levy in 2013, became the default early-stage instrument; the docs are free on YC's site.
- The NVCA publishes free model financing documents that define "market standard" for US priced rounds.
- "Venture Deals" by Brad Feld and Jason Mendelson is the standard founder reference on term mechanics.
From a founder's point of view
Valuation is the number founders brag about; the terms are the numbers that decide what you keep. A clean term sheet at a fair price beats a headline valuation with teeth hidden in it.
Rule of thumb
If you can't explain to your cofounder what a clause does to your payout at exit, you're not ready to sign it.
