I am a lawyer. I litigated cofounder disputes for years. So take this answer as coming from inside the house: for most founding teams at the pre-incorporation stage, the first thing you need is not a lawyer. It is your actual promises, made explicit, written down, and signed while everyone still likes each other.
That sentence would have cost you a consultation fee. The rest of this note explains it, and tells you when it stops being true, because it does stop being true.
What you are actually paying for
When a firm charges thousands of dollars for a founder agreement, you are paying for two different things bundled together. One is drafting: turning decisions into clauses. The other is judgment: assessing your specific situation, spotting the risk you did not see, qualifying the messy facts.
Here is the uncomfortable part: at the pre-incorporation stage, for a standard team, the drafting half is largely commodity work. The twelve conversations a founder agreement covers, the twelve points, are known, the market standards (four-year vesting, one-year cliff, IP to the project) are known, and no lawyer can have those conversations for you. The decisions are yours. What most early teams buy for five figures is a beautifully typed version of decisions they still had to make themselves, delivered as a static document nobody reopens.
The expensive part of a lawyer is judgment. Do not pay judgment prices for typing.
When a lawyer is non-negotiable
Judgment is exactly what you should pay for when your situation stops being standard. Concretely:
Entangled IP. One founder built the prototype while employed elsewhere, or is bringing code, patents or a brand from a previous venture. Whether that IP is actually theirs to contribute is a qualification question, and getting it wrong poisons everything downstream.
Real money or real assets already in play. Meaningful personal investment, an existing revenue stream, a company being restructured into the new project.
Cross-border founders. Different countries mean different default rules on IP, non-competes and enforceability. The standard answers stop being standard.
Incorporation itself. The moment you form the company, issue shares and translate the founder agreement into charter documents and stock purchase agreements, professional review earns its fee. The same is true the day an investor puts a term sheet in front of you.
Anything already contested. If a dispute has started, you are past prevention. Get counsel.
And one boundary worth stating plainly, because it is the honest one: writing down what you and your cofounders have decided is not practicing law. Assessing whether your specific situation needs something different is. A good tool does the first and tells you when you have crossed into the second.
The trap in the question
Notice what the question "do we need a lawyer?" often hides: it becomes the reason to do nothing. The team that cannot afford five figures concludes the agreement can wait, and the most fragile months of the company stay ungoverned. Between an expensive static document and nothing at all, teams overwhelmingly choose nothing.
That is the actual failure mode. Not "they used a tool instead of a firm." It is "they had no written deal at all, and then the dispute arrived."
