Don’t Lose a Great CoFounder, Whatever It Takes
Джейсон Лемкин из SaaStr Fund утверждает, что почти все его неудачи как CEO и фаундера связаны с тем, что он вовремя не сделал одного ключевого найма, а сооснователь — самый сложный и важный из них. По его данным, 90% публичных SaaS-компаний имели двух и более сооснователей, и портфельные компании SaaStr Fund без активного сильного со-фаундера сейчас, в эпоху AI, переживают трудности заметно сильнее. После расставаний с сооснователями обычно падает скорость разработки продукта, становится гораздо сложнее запустить второй продукт и в целом труднее играть вдолгую, что часто ведёт к более ранним экзитам. По данным Carta, 25% стартапов теряют сооснователя к четвёртому году. Главный совет: если сооснователь по-прежнему сильный исполнитель и предан делу на 90%, не отпускайте его — гасите конфликты в зародыше, зовите на помощь, разговаривайте и проявляйте эмпатию. В качестве примера автор приводит Brian и Dharmesh из HubSpot, чьи отношения за 20 лет менялись, но глубина уважения сохранилась.
Don’t Lose a Great CoFounder, Whatever It Takes

So when I look back on my many failings as an entrepreneur, in the end, it’s all about the team.
Almost all my failings as a CEO and founder came from failing to get that one extra great VP hired, that one critical hire.
And cofounder is the most complicated of all. Yes, some of the best can do it without a co-founder. But 90% of public SaaS companies had 2 or more co-founders. And personally, I”m just not good enough to be great without one.
And I have only truly flown when I’ve had a great co-founder. I’ve done OK without one, and kept the engines going, the plane in the air. And I’ve also found a great co-founder later. They don’t always have to be there on Year 1. You can even find one years down the road.
And I’ve come up short of my potential when I let co-founder conflict become a real issue.
I get it, when it happens. Especially when one cofounder is more passionate about the business. When one is an 11 in terms of passion and commitment, and another is an 8 or 9. Or really smart, but a 7.
But what I think I’ve learned is even if your co-founder isn’t quite as committed as you, if they are still a 10 as an executive, and they are 90% of the way there in terms of commitment … don’t let them, go.
At least not unless you are 100% sure you have someone better on deck.
What I’ve seen after co-founder break-ups, more often that not, is:
When I look across the SaaStr Fund portfolio now, from start-ups just starting to $2.5B exits and several at well past $300m ARR, one thing is clear: the ones without an active great co-founder are struggling more.
Especially now, in the Age of AI.
Finding a truly epic cofounder
Having a truly insanely great partner
At work or at home
It's pretty rare
Never let 'em go

All I can tell you is this: if co-founder conflict is building, try to nip it in the bud.
Bring in help. Talk it out. Tell yoru co-founder you love them — if you do. Be empathetic. Stop being hurt, if you are hurt. Get past it.
Sometimes, you do have to break-up with your co-founder. I get it.
But I’ve talked several teams back from the edge. Not my favorite job, but one I am OK at. Because I’ve lived it. And seen what happened to me when I lost a truly great co-founder.
Try harder, if they are great. Try again. One more time.
Even if they aren’t what they once were, don’t let the great ones go, if they are still great. Or even just close to great. A co-founder knows so much, so deeply. It’s almost impossible to replace that. Even at $100m-$200m ARR, it’s hard. Even after that.
This stuff is hard. Per Carta, 25% of start-ups lose a co-founder by Year 4:

Look at these 2 co-founders, Brian and Dharmesh of HubSpot. Their relationship has changed a lot over the years. Dharmesh stop managing a team a long ways back. Brian much, much later moved to Chairman from CEO. But the depth of that relationship, and respect, is clear in this SaaStr deep dive. 20 years in.
