Module 2 of 6 — Founders' Agreements and Startup Legal Setup

Founders' Agreement: Equity, Roles, and Dispute Resolution

Reading module · approx 14 min

A founders' agreement is the contract between co-founders that governs their relationship, their equity stakes, their roles, what happens if one of them leaves, and how they resolve disputes. Most startups that break down do so because this agreement was either not made at all, or was made too informally to be enforceable at the moment it matters.

Why you need a founders' agreement

The company's articles of association (AoA) govern the relationship between shareholders as a whole, but they are not specific to founders. A founders' agreement supplements the AoA with specific provisions about:

Each founder's equity stake and the basis on which it was determined
Each founder's role, responsibilities, and time commitment
Vesting: the schedule on which each founder earns their equity (covered in Module 3)
What happens when a founder leaves: unvested equity is returned, vested equity is subject to ROFR or forced sale mechanisms
Key decisions that require unanimous founder consent (major pivots, fundraising terms, sale of the company)
IP assignment: all IP created by founders for the company is assigned to the company
Confidentiality and non-compete during and for a period after the founder's departure
Dispute resolution between founders

Equity split: how founders get it wrong

The single most common mistake in early startups is an equal equity split between founders regardless of the differences in contribution, risk, and role. A 50:50 split between two founders sounds fair but creates a governance deadlock whenever there is a meaningful disagreement — neither founder can break the tie.

The founder equity split should ideally reflect:

Who had the idea and how much credit attaches to ideation vs. execution
Who is working full-time vs. part-time from day one
Who is contributing capital, assets, or IP to the venture
Who has the domain expertise, network, or credentials that are most critical to the company's success
Who is taking the most personal financial risk

A rough heuristic: the person who will be the CEO or primary driving force should have enough equity to maintain meaningful control. A split that will eventually become 35:35:30 (after dilution) leaves no one in control.

Roles and responsibilities

The founders' agreement should specify each founder's role and their scope of authority. Key provisions:

Who is the CEO and what decisions does the CEO make unilaterally?
What decisions require a majority of founders?
What decisions require unanimous consent of all founders?
What happens if a founder is unable or unwilling to perform their agreed role?

Dispute resolution between founders

Disputes between founders are common and often existential for the company. The founders' agreement should provide:

A negotiation period before formal dispute resolution begins
A senior management escalation mechanism (where companies have outside advisors or independent directors)
Arbitration with a specified seat and institutional rules
Deadlock resolution for tied votes: casting vote for the CEO, rotating chair, or buy-sell mechanisms

The shotgun clause A shotgun (or Texas Shoot-Out) clause is a deadlock-breaking mechanism: one founder names a price, and the other founder must either buy the first founder's stake at that price or sell their own stake to the first founder at the same price. This creates an incentive to name a fair price (because you don't know which side you'll be on) and resolves deadlocks without court intervention. It is most useful when there are exactly two founders with equal stakes.

Module 3 covers vesting — the schedule on which founders earn their equity and the most important protection investors look for before writing a cheque.
