Term sheet negotiation: the clauses founders should model before signing

The headline valuation attracts attention, but the economics and control provisions around it determine what the deal really means. A term sheet should be modelled as a complete system. Founders need to understand both the next financing and the range of outcomes that could follow it.

Model dilution on a fully diluted basis

Start with the cap table immediately before financing. Add the new money, any option-pool increase, converting instruments, accrued interest, and promised grants. Then calculate ownership after the round for founders, employees, existing investors, and the new investor. This prevents a superficially attractive valuation from hiding unexpected dilution.

Read liquidation preference as outcome allocation

A standard one-times non-participating preference may appear simple, but its impact changes with exit value. Participation rights, multiples, dividends, and seniority can materially redirect proceeds. Model low, medium, and high exit scenarios rather than evaluating the clause in isolation.

• Compare participating and non-participating outcomes
• Test stacked versus pari passu preference
• Include accrued dividends where applicable
• Show founder proceeds, not only company value

Treat the option pool as part of price

If the pool is increased before the financing, existing holders absorb that dilution. Ask how much hiring capacity the operating plan genuinely requires and how existing unallocated options are counted. A few percentage points can change the effective price of the round substantially.

Protect operating control

Board composition, investor consent rights, founder vesting resets, and information rights affect how the company can be run. The objective is not to remove investor protections. It is to ensure they are proportionate, precise, and compatible with ordinary operating decisions.

Negotiate from the whole package

Founders create leverage by comparing complete offers, not isolated valuation numbers. Speed, partner quality, reserves for future rounds, governance expectations, and closing certainty all matter. The best term sheet is the one that supports the company through the next stage without creating avoidable constraints.
