When a founder agreement becomes urgent

The first trigger is incoming capital. As soon as a founding group is in serious conversation with an investor — whether angel, syndicate, or institutional — the founder agreement moves to the top of the queue. Investors will not close into a cap table that is undocumented. The diligence checklist always asks for the founder agreement, the IP assignment, and the vesting schedule.

Closing under time pressure with these documents missing is how unfavourable terms get accepted. Closing with the documents already in place lets the founding group negotiate from a stable starting point.

The second trigger is when the contributions of the founders begin to differ in kind. Two founders splitting work fifty-fifty is a stable structure on day one. Six months in, when one founder is full-time and one is half-time, the equity split that was fair on day one is no longer aligned with the contribution.

Re-balancing equity after the fact is harder than setting vesting up front. A founder agreement with a vesting schedule and a clear role definition handles asymmetry without requiring a renegotiation. A handshake does not.

The third trigger is the appearance of a second product, a second revenue line, or a meaningful pivot. The original handshake was made about the original product. A founding group that is now running two distinct workstreams needs to document who owns what, who decides what, and what happens if one workstream is spun out, sold, or shut down.

This trigger is the one most commonly missed. The pivot is usually framed as a product decision; the legal structure underneath the pivot is rarely revisited at the same moment.

The four core topics in any founder agreement are equity ownership, vesting and good-leaver mechanics, IP assignment, and decision rights including deadlock resolution. A short founder agreement that covers these four well is more useful than a long one that hedges on all of them.

The agreement is also the document that will be read first if the founding group ever considers parting ways. It is worth drafting with that future read in mind, not just the present good-faith one.
