Founders rarely fall out over the idea. They fall out over money, control, and what happens when someone wants to leave. A shareholders’ agreement is the document that answers those questions before emotion and money are on the table, which is the only time it can be answered fairly.

Why the company’s constitution isn’t enough

Standard incorporation documents govern the company’s basic mechanics, but they say little about the relationship between the founders. A shareholders’ agreement fills that gap with the terms that actually protect each party as the business grows and outside capital arrives.

The terms that matter most

  • Governance and decision-making: who sits on the board, and which decisions need a supermajority or unanimous consent;
  • Capital contributions: who funds what, and what happens if someone can’t or won’t;
  • Share transfers: pre-emption rights, drag-along and tag-along, so no one is trapped or blindsided by a sale;
  • Vesting and leaver provisions: what happens to a founder’s equity if they leave early;
  • Deadlock and exit mechanisms: a defined route out when the founders cannot agree.

Vesting: the clause founders regret skipping

Without vesting, a co-founder who leaves after six months can keep a full equity stake while everyone else builds the company for years. Vesting ties equity to continued contribution, and it is far easier to agree at the start than to claw back later.

Getting it right before you raise

Investors will expect a proper shareholders’ agreement, and they will price the risk of not having one. Putting it in place early signals a well-run company and removes a common obstacle in a funding round.
