Term sheets get compared on valuation, dilution, and pro rata. The variables that actually matter — temperament in a hard quarter, behavior in a down round, willingness to wait — never show up on the page.
That is exactly why they end up being the variables that determine the next ten years of the company.
What the term sheet hides
A term sheet is a snapshot of an agreement in good times. It says almost nothing about what the relationship will look like the first quarter you miss plan, the first executive who leaves badly, the first time the market turns.
Founders optimize the term sheet because it is the document in front of them. They under-optimize the relationship because it is invisible until it isn't.
Reference investors like executives
If you would do four reference calls before hiring a VP of engineering, you should do six before letting an investor onto the cap table. The investor will be there longer than the VP and will have more leverage in the moments that matter.
Talk to two founders the investor backed who succeeded, two who struggled, and at least one who failed. The third group will tell you more than the first two combined.
The questions to ask
How did they behave the quarter you missed plan? What did they do when you wanted to fire an executive they had introduced? Did they show up for you in the down round, or did they get quiet? How did they communicate with your board when things got hard?
These are not soft questions. They are the only ones that matter.
What the right investor actually buys you
The right investor makes you bolder in year four. They give you permission to take the hard swing, hire the expensive executive, kill the underperforming product line. The wrong investor does the opposite — they make you smaller, more cautious, more focused on the next round than the next decade.
Both wire the same amount. Only one is worth the dilution.
Valuation is a number. The investor is a decade. Spend your diligence accordingly.
