The founders' agreement: why startups ignore it (and how that can destroy them)

14 April 20267 min read

Two friends. A great idea. A startup full of enthusiasm. And no founders' agreement. "We're friends — we'll always work it out." We hear this all the time. And we regularly see how it ends.

What is a founders' agreement?

A founders' agreement (also called a shareholders' agreement) governs the rules of co-existence between shareholders in the company. It isn't legally required, but it's one of the most important documents a startup can have. While the memorandum of association is a public document with content prescribed by law, the founders' agreement is a private arrangement capturing what doesn't belong in the Commercial Register.

Why isn't the memorandum of association enough?

The memorandum covers the formal mechanics of the company — who is the director, how voting works, what the share capital is. But it doesn't address:

  • What happens if one of the founders leaves after six months
  • Whether a departing founder can go work for a competitor
  • How proceeds are split in the event of a sale
  • Who has veto rights over key decisions

What should a founders' agreement contain?

Vesting

Shares "unlock" gradually over time. If a co-founder leaves after 6 months, they don't take their full stake. Standard vesting: 4 years with a 1-year cliff — after one year you receive 25% of your interest, then 1/48 per month thereafter.

Cliff

The minimum period before vesting begins — typically 1 year. If you leave before the cliff, you get nothing. Harsh? Maybe. But it saves companies.

Drag-along

If majority shareholders want to sell the company, they can "drag" minority shareholders along. Without drag-along, a minority shareholder can block the entire exit. Investors always require this.

Tag-along

A minority shareholder has the right to sell their stake on the same terms as the majority. This protects minorities — the majority can't sell to a strategic buyer without giving the minority the same opportunity.

Non-compete and non-solicitation

What happens if a founder leaves and starts a competing business? Or poaches your employees? Without clear clauses, you're left fighting it in court — which is slow and expensive.

Deadlock mechanism

How do you resolve a situation where two 50% shareholders disagree on a key decision? Without a clear mechanism the company can end up paralysed. Solutions: mediation, a "shotgun" clause, or the right to buy out the other party at a pre-agreed price.

A real-world story

Jan and Pavel built an e-commerce startup together. Jan led tech, Pavel ran sales. Things were going well — until Pavel decided to leave. Because they had no founders' agreement, Pavel walked away with a 50% stake and no obligation not to compete. He started a similar business, poached two key employees, and Jan eventually had to sell the company for a fraction of its value.

A founders' agreement would have solved all of this upfront — at a fraction of what Jan ultimately paid.

When should you sign it?

Ideally right at the start — before you invest the first money or approach the first customers. The longer you wait, the harder it is to agree on terms (everyone's expectations solidify over time).
