Your cofounder problem is a business problem

01 — What's at Stake

I'll be straight with you. If you and your cofounder don't figure this out, here's what happens:

You keep having the same fights. Or worse, you stop fighting altogether and just avoid each other. Difficult decisions pile up. Competitors surge ahead. Customers churn. Trust keeps eroding. Neither of you feels motivated to bring your best anymore.

Fast forward a few months and the risk of something irreparable is nearly guaranteed. Someone says the wrong thing. Someone makes a unilateral decision.

• You question your own judgment and competence as a founder and leader
• Your company fails for self-inflicted reasons, or its success is a fraction of what it could have been
• One or both of you leaves the company you sacrificed so much to build
• There's an expensive, painful effort to buy back shares or restructure equity

None of this is inevitable. But doing nothing makes all of it more and more likely.

02 — Who I Am

I'm Jason Shen—3x founder and Y Combinator alum. I've been a product leader at Meta and Etsy, a growth marketer at a Sequoia-backed enterprise software company, and the author of The Path to Pivot: The Playbook for Founders Who Want to Rebook their Startup. I've been in the room when cofounder relationships fall apart. Including my own.

My first company failed to take off because we as cofounders lost the ability to make hard decisions. My second and third companies fared better thanks to an executive coach who helped our team endure through hard times. After our exit, I found myself studying with the Gottman Institute, the gold standard in relationship science, to understand what actually makes partnerships work and how to repair them when they don't.

Since 2020, I've coached over 50 founders and startup teams on building uniquely valuable enterprises. I've struggled through pivot hell. I know what fundraising pressure feels like. I know what board dynamics do to a relationship. I've lived it.

Today I focus on helping cofounders reset, repair, and rebuild their most valuable asset: their partnership.

03 — What This Actually Is

You'd be mistaken to think that cofounder coaching is just...

• A series of venting sessions about your cofounder to a coach
• An awkward, cringe, or humiliating experience
• A cold, impersonal framework that treats people like APIs
• A sign that you aren't compatible with each other

Here's what it actually gives you.

• New skills for communicating with each other, especially when it's hard
• The ability to talk about what actually matters without yelling, bickering, or going silent
• Perspective to understand where your cofounder is coming from without making yourself wrong
• Tactical ideas for how the two of you can work better together, starting now
• A space to feel heard, valued, and understood
• The kind of support where you'll be able to laugh, loosen up, and feel way more optimistic about the future
• The confidence to deal with conflict instead of avoiding it

“That positive needs exercise you did for the three of us worked wonders, and I'm already seeing that impact in the way we communicate.”

04 — The Method

Resetting the Bones

Here's what I believe: you chose each other for a reason. The foundation was there from the start. In some ways, this is just a tragic misunderstanding of epic proportions.

But understanding takes real cognitive, emotional, and physiological effort to reach. And demonstrating that understanding matters just as much as having it, and is just as hard to do.

The approach: My method works differently because it does three things most approaches don't:

1. Name the exit early. Not as a threat. As reality. This relationship is either going to get meaningfully better, or you're no longer going to be in it. Naming that frees you both from feeling trapped. You're not hostages. You're choosing to stay and do the work.
2. Go deep on each founder. Family history, career path, what shaped you. Most cofounders are fighting about the present without understanding the history each person carries into the room. When you see the patterns underneath, behavior that seemed inexplicable starts making sense.
3. Treat conflict as a physiological problem, not just a cognitive one. When your nervous system is in fight-or-flight, you can't listen. You can't empathize. You can't think straight. I teach you to regulate yourself before trying to have hard conversations.

What we do: Your relationship did not deteriorate overnight, and it will not be solved overnight either. But bit by bit we will get you out of the mud, wash you off, and resettle on dry land. Here's how:

1. Learn to talk about hard things. Process past fights. Practice empathetic listening. Challenge yourself to validate what matters to the other person, even when you don't fully agree.
2. Rediscover the good. Go back to the beginning. The early friendship, the decision to start a company together, early wins. Rebuild genuine appreciation for what each person uniquely brings.
3. Build the new partnership. Small wins, small compromises, regular check-ins. Turn toward each other instead of away. Practice until the new patterns stick.

05 — The Program

A 13-Week Partnership Intensive

This is a structured program, not open-ended coaching. Here's how it works:

What's included

• 8 facilitated team sessions
• 2 individual sessions with each founder
• Deep individual founder assessments
• Structured homework between sessions
• Video resource library
• Optional quarterly follow-up support

Investment: Starting at $12,000

Payment plans available

All impacted cofounders must participate and commit to the process for the duration of the program.

“There's no way [cofounder] and I could have stayed friends if you didn't coach us through the separation. I felt like we could easily gone to a pretty bad place if it weren't for you. We're actually working with his new company — they're our client.”

— H.V., Founder & CEO of Agentic Marketing Platform (Amino Capital)

06 — What Changes

Here's what I get most excited to see:

Your day-to-day gets lighter. Easier. More enjoyable. You stop burning energy on the relationship and start focusing it on the hard problems in your business.

You get hope that when relationships falter, they can be repaired and come back even stronger.

You renew your faith in the business because you know there's a partner beside you who truly believes in a shared vision and is committed to making it work.

You pick up skills and experiences that benefit every other relationship in your life.

And when the business hits rough patches (it will), it feels less crushing because you gave it your all with someone you really trust by your side. When the business succeeds (and it can), it's that much sweeter because you get to share that victory with someone you genuinely like, respect, and care about.

That's the whole point. More trust. More connection. More partnership. More love.
