The Co-Founder Conversations You Need To Have Before You Incorporate
Equity, vesting, roles, money and the exit nobody wants to picture: the five talks that decide whether a founding team survives its first real disagreement.
The cheapest moment to settle a co-founder dispute is before the company exists. Once shares are issued, a bank account is open and the first customer has paid, every unresolved question about who owns what and who decides what gets more expensive to answer, and it usually gets answered under pressure.
Most founding teams skip these conversations for an understandable reason. They feel like a vote of no confidence in the friendship or working relationship that made starting the company feel possible. That instinct is backwards. Teams that have talked through the hard scenarios early tend to treat later conflict as a process question rather than a betrayal.
What follows are the conversations worth having, in roughly the order they should happen, and what each one should produce on paper.
1. The equity split, and the reasoning behind it
An equal split is not wrong, but it should be a decision, not a default. Talk through who had the idea, who is building the product, who is bringing in revenue or capital, and who is committing full time from day one. Then agree on a number and, just as important, write down why. A reason recorded at the start is far harder to relitigate two years later than a number that simply appeared on a cap table.
The split also needs to reflect what happens next. If one founder is staying in a salaried job for six more months, say so, and decide whether that changes the percentage or the vesting start date.
2. Vesting, cliffs and the 83(b) deadline
Founder shares should almost always vest. A common structure across US startups is four years with a one-year cliff, meaning nothing vests if someone leaves in the first year, and the rest vests monthly or quarterly afterward. Vesting protects the founders who stay. Without it, a co-founder who leaves in month eight walks away with a full stake in a company that others will spend years building.
Discuss acceleration too. Single-trigger acceleration vests shares on an acquisition. Double-trigger acceleration requires both an acquisition and a termination. Investors tend to have firm views on this, so a founding team that has already agreed among itself is better placed when the term sheet arrives.
When founders receive restricted stock that is subject to vesting, US tax law gives them the option of a Section 83(b) election, which must be filed with the IRS within 30 days of the stock being issued. The deadline is unforgiving, and missing it can change how the shares are taxed as they vest. Assign one person to own this step, and have every founder confirm in writing that theirs was sent.
3. Roles, money and who breaks a tie
Titles matter less than decision rights. Agree on who owns product, engineering, sales, hiring and finance, and what kinds of decisions require both or all founders. Then settle the uncomfortable part: who is the CEO, and what happens when two founders disagree on something that falls in nobody's lane.
Some teams give the CEO the final call on anything not explicitly reserved. Others name a trusted outside adviser as a tiebreaker for specific categories. Either can work. Having no answer is the version that fails, because deadlock in a two-person company with a 50-50 split can stall the business entirely.
Founders arrive with very different financial situations, and those differences surface fast. Discuss how long each person can go without a salary, whether anyone is lending the company money or paying expenses personally, and how that will be documented. A founder loan should be a written loan, not a vague understanding that money will come back someday.
Talk about hours and geography too. If one founder expects nights and weekends and the other expects a sustainable pace, that gap will show up in the first crunch. If someone plans to move, have a child or take a sabbatical, it is better discussed now than discovered later.
4. The departure scenario
This is the conversation people avoid most, and it is the one most likely to matter. Agree on what happens if a founder leaves voluntarily, is asked to leave, becomes unable to work, or dies. Unvested shares typically return to the company. Vested shares may be subject to a company right of first refusal or a repurchase right, and the price mechanism for any buyback should be defined in advance rather than negotiated in the middle of a breakup.
Every founder should also sign an agreement assigning to the company the intellectual property they create for it, including anything built before incorporation. Investors check for this in due diligence, and a missing assignment from a departed founder is one of the most common and avoidable problems they find.
What to do this week
Book two long sessions with your co-founders and work through each section above. Write the outcomes in plain English first, then take that summary to a startup attorney who can turn it into a founders' agreement, stock purchase agreements with vesting, and IP assignment documents. Calendar the 83(b) deadline the day shares are issued. Then put a date on the calendar a year out to reread what you agreed, and to fix anything that no longer reflects how the company actually works.
