- Vet your potential co-founder more closely to make sure they have the skillsets they claim to
- Pay attention to red flags and deal with them sooner. Withholding the admin password, for example, was a clear one.
- Maybe build in a non-confrontational exit from the beginning. Sounds like the co-founder was trying to bullshit their way through it so they wouldn't lose out if the product did well. Perhaps a small amount of equity would have been an easier way to push them out?
> this is one of the reasons Founder Vesting is a thing. There should be a mechanism in place which strips the founder of equity when they quit.
I would urge you not to refer investors to this article and instead just try to explain in simple terms that you felt your co-founder did not respect the timelines that were critical for your company. And list the facts, not your opinions.
Update: By the way, I'd like to add that it's clear you had a rough ride with this one and I don't feel unsympathetic. But I wouldn't want you to struggle with it any longer than is necessary. Best of luck.
But sharing that specific article is a mistake, instead just stating it without emotion is probably better.
I know it's tough, I was in a similar position with a cofounder who really didn't work out and I really resonate with that line "I do miss that naive me though, there is something wonderful in trusting your fellow man that I can never quite regain, which is a shame.". My experience also made me lose that bright sunshine of naivety and easy trust that I had and for a long time I was incredibly bitter about my ex cofounder. But, it's not a good strategy to be publish it with a wording this emotional, instead just being very matter of fact about it, describing the main issues in broad terms is enough.
If you need to share your anger with the world, this quality essentially has nothing to do with your former partner, but has everything to do with your future partners' perception of your coping strategies. The red flag is that you may spend unnecessary energy holding on to things.
The mark of responsibility is sucking up and admitting that it was 100% your mistake, and that he was just a particularly tall rock you had to climb.
To quote a musician, scream it to the trees. (Ventilate to those for whom it has zero cost; your spouse, your friends; not all potential future partners.)
