This guide is written for startup founding teams with two or more cofounders. If you’re starting a small business with one or more partners, many of the same principles apply: getting ownership in writing, defining roles, and planning for departures. The document that covers this ground for small businesses is typically your operating agreement. Takeoff can generate an operating agreement tailored to your business.
A founders agreement is a written document between the people starting a company together. It records what everyone agreed to about ownership, roles, decisions, and departures. Some founding teams start with a detailed formal document. Others begin with a clear written summary and build on it as the company evolves. The format matters less than having something in writing that everyone has signed.
The most important function of a founders agreement is making implicit assumptions explicit. Most cofounders start out aligned on the big picture but diverge on specifics they never discussed. One person assumes equal equity. The other assumes the person who brought the idea gets more. One assumes full-time commitment starting now. The other plans to stay at their job for another six months. These gaps only surface when something goes wrong, and by then they’re much harder to resolve.
Equity ownership — who gets what percentage and on what terms. This is the most common source of cofounder disputes. Getting it in writing early, even if the numbers change later, creates a shared starting point.
Vesting — how ownership is earned over time. A standard structure is four years with a one-year cliff, meaning a founder who leaves in the first year walks away with nothing, and after that earns their share gradually. Vesting protects everyone on the team from someone leaving early with a large equity stake.
Roles and decision-making — who handles what, and how major decisions get made. Some teams give each founder authority over their domain. Others require consensus on big calls. What matters is that the process is defined before a high-stakes disagreement forces the question.
Departure terms — what happens if a founder leaves voluntarily, is asked to leave, or can’t contribute anymore. This is the section most teams skip because it feels premature or uncomfortable. It’s also the section that matters most when things get difficult.
IP assignment — confirming that work done for the company belongs to the company, not the individual founder. This is especially important when founders are building before the company is formally incorporated.
Contributions and compensation — whether founders are contributing capital, working full-time or part-time, and whether anyone draws a salary. Misaligned expectations about commitment are a common source of friction.
Dispute resolution — how disagreements are handled. Options range from a simple mediation-first clause to formal arbitration. Having any process beats having none.
The best time is before you start building together. The second best time is now.
Many founding teams avoid this conversation because it feels awkward or premature. The business is just getting started, everyone is excited, and talking about departures or disagreements feels like planning for failure. But the conversation is actually easier the earlier you have it, because the stakes are lower and the emotions are calmer.
If a founding team has already been working together for months without a written agreement, that’s normal and common. Having the conversation now is still valuable. What matters is getting to a shared understanding and putting it in writing before a real disagreement forces the issue under pressure.
Without a written agreement between founders, critical questions about equity, departures, and decision-making are either left to state default rules or simply undefined. For teams that haven’t incorporated, state partnership law fills the gaps, and those defaults are rarely what founding teams would choose. For teams that have incorporated, the entity’s formation documents cover the corporate structure but typically don’t address the founder relationship in detail: who gets what if someone leaves, how major disagreements are resolved, or how roles evolve as the company grows. In either case, a cofounder who departs without clear written terms can create disputes that are far harder to resolve after the fact.
IP ownership can also become unclear. If a founder built the product before incorporation and never formally assigned that work to the company, questions about who owns what can surface at the worst possible time.
For founders planning to raise funding, investors typically review the founders agreement during due diligence. Not having one creates friction and delays at exactly the moment when momentum matters most. Getting aligned as a team before the company has significant value is far easier than negotiating terms after the stakes have grown.
A few things that tend to make this conversation go well:
Once a founding team has agreed on the key terms, putting it in a proper document protects everyone. Takeoff can generate a founders agreement tailored to your team size and structure. The generated document covers equity, vesting, roles, departures, and IP assignment based on your inputs.
Some founding teams start with a simple written summary and formalize it later when they incorporate. Others want a complete document from the start. Either approach works as long as everyone has signed something that reflects the actual agreement.
If the situation involves unusual terms (unequal vesting schedules, performance-based equity, intellectual property from a prior employer), Agapius can help you think through whether the standard structure fits or whether your situation needs a different approach. For straightforward agreements between two or three founders, the standard terms are well-established and widely used.
