Your Cofounder Has Stopped Working and You Already Signed 50/50

Eighteen months in, you're doing standup alone

He misses it again. Third time this month. There's a message at 11:40 saying sorry, was on a call — and you know which call, because you know about the side contract, even though neither of you has ever said the words out loud.

So you do the work. Then you do his work.

And at some point in the evening you draft the message, get it to about four paragraphs, read it back, and delete it. You've been doing that since March. Five months of drafts.

He owns half the company.

Everything written about this is addressed to you eighteen months ago

Use vesting. Sign a founders' agreement. Have the hard conversation early.

All correct. All now functioning purely as blame. You know. You were there when you didn't do it, mostly because doing it would have meant implying that your friend might one day stop showing up, which at the time felt like an insult.

So put that aside. What's left is two separate problems that almost everyone insists on treating as one: a work problem and an ownership problem. Different fixes, different timelines. And if you open with the ownership one, you will never get a truthful answer to the work one.

Find out what actually happened first

You have a theory. Your theory is that he's checked out and is riding your effort while holding half the equity. You may well be right.

But there are at least three things this commonly turns out to be, and the response differs for each.

Burnout. The tell is which work has stopped. Burnout takes out the initiating work first — cold outreach, hard decisions, anything requiring a standing start — while the reactive work survives longest. Someone burnt out can often still answer. What they can't do is begin.

A decision already taken. He's leaving and hasn't said so, sometimes because he hasn't fully admitted it to himself. In that reading the side contract isn't a symptom, it's the transition, already underway. The tell is financial: he is quietly building an income that doesn't need this company to work. Watch what he protects when something has to give.

A mismatch in what full-time meant. More common than founders like to admit. You both said full-time. You meant sixty hours and no other commitments; he meant a serious job's worth of effort plus the flexibility that comes with owning the place. Neither of you wrote it down, and you've each spent a year privately appalled at the other.

If it's that third one, he doesn't believe he's done anything wrong — and the four-paragraph message you keep drafting will land like an ambush.

You cannot tell which it is from the outside. That's the entire point of the first conversation.

The diagnostic conversation

No equity in it. None. Say the word and everything after it becomes a negotiation, and you'll learn nothing true.

In person if you can, somewhere neither of you is the host. Open with facts and no adjectives — because adjectives are the thing that turns this into a fight about whether you're being fair.

Roughly: over the last three months I've done the customer calls, the releases and the investor updates, and you've been on the other contract two or three days a week. I don't want an argument about it. I want to know what you want the next year to look like.

Then be quiet for an uncomfortably long time. Longer than feels reasonable. The first thing people say is a defence; the second thing is often the truth.

What you're listening for isn't an apology. It's whether he describes a future with the company in it, in specific terms, containing things he will personally do.

All three diagnoses are workable. The unworkable outcome is the one you've been living in, which is no answer at all.

Then, on a different day, the ownership conversation

Different day. Ideally a different week.

And before it, read what you actually signed. Not what you remember signing. Get the documents out.

Is there vesting on the founder shares, and if so, what's the cliff, what's the schedule, and is it running from incorporation or from some later date? Are the shares subject to a buyback or repurchase right? Does anything address what happens if a founder stops working full-time? Who controls the board seats? Is there a shareholders' agreement separate from the articles, and have you read that too?

Most people in your position find one of two things.

Either there is vesting and they'd half-forgotten, in which case time is quietly on your side and the argument for acting now rather than after another year has accrued is obvious. Or there's nothing, and half the company is simply his.

If it's the second, be honest with yourself about your position: you have no legal lever, and everything from here is a negotiation between two people, one of whom can say no and walk. That's uncomfortable, and it's also clarifying. Your currency isn't rights. It's the plain fact that a company with a disengaged fifty-per-cent holder is worth dramatically less to everybody, him included, and that the only person who can currently fix that is you.

What to propose

It depends on what you found, which is why the order matters.

If he's leaving: a negotiated reduction that still leaves him something real for what he built. Founders in your position usually want him to end up with zero. Zero is rarely achievable and rarely fair — he did build the first part of this, and a deal he considers insulting is a deal he'll fight, slowly, at exactly the moment you need a clean cap table.

If he's staying at a lower intensity: change the role and the title honestly, and change the equity to match what he's actually going to do from here. The trap is a fudge that lets everyone avoid saying the word part-time. Fudges don't survive diligence and they don't survive a bad quarter.

If it's burnout: a defined break with a return date and a specific description of what returning means. And say the second half out loud — that if the return doesn't happen, you'll be back in this conversation, and it'll be a harder one.

All of that touches share transfers, company law and tax. Those vary enormously by country and can go wrong in ways that are expensive and hard to reverse — a badly executed founder share transfer can produce a tax consequence for one or both of you on shares nobody has been paid for. Get a startup lawyer to draft or review anything before it's signed. Not to have the conversation for you. To make sure the thing you agree is the thing that actually happens.

Don't leave it for investors to find

The tempting option is to keep going and deal with it at the next raise.

Two reasons that's the worst available choice. Diligence asks who does what, and it talks to your team, and your team knows. A founder problem you disclosed and handled imperfectly is survivable; one that gets discovered is read as information about your judgement rather than his.

And the arithmetic keeps running in the meantime. Every month you don't have this conversation, more of what you personally build gets owned by someone who isn't building it.

The friendship

Here's the sentence nobody writes: you may lose it.

Not certainly. But possibly, and probably for a year or so even in the versions that recover.

What seems to matter most isn't the outcome of the negotiation. It's whether he hears it from you or from a lawyer's letter, and whether you talked about the work before you talked about the money. That's the whole reason for the order.

There's also a version where the friendship survives intact and the company doesn't survive the compromise you made to protect it. Which of those you'd rather have is a question about what you want the next few years of your life to contain, not a business question, and there's no general answer to it. It's worth knowing what you'd choose before you're in the room.

Rehearsing it

Five months of drafts isn't indecision. It's rehearsal without a partner.

TrueTalk has an AI advisor called Sally Startup, a serial entrepreneur persona whose areas are startup founding, product development and venture capital. It's an AI advisor — not a human cofounder coach, and not a lawyer — but you can say the whole thing out loud with the real history in it, at midnight, and hear how your opening lines sound coming back at you. The first conversation is free, then it's a subscription. Anything touching the documents still goes to a lawyer.

Pick the date

This week. Not this quarter.

Send the invite with an unremarkable title and a real slot in it, because the conversation you've been avoiding does not get easier with age, and the only thing that changes while you wait is the size of what you're arguing about.
