This is an incredibly brave, and hopefully cathartic post by someone I greatly admire. I really hope he is able to find the support and peace he needs.
As a bit of an aside, I wonder how much of this has led to similar troubles for other founders:
When the Foundry investment closed, we redoubled our efforts to build Moz Analytics. We hired more aggressively (and briefly had a $12,000 referral bonus for engineers that ended up bringing in mostly wrong kinds of candidates along with creating some internal culture issues), and spent months planning the fine details of the product.
I've heard from friends & colleagues about the massive amount of pressure they've felt after closing an investment round. While fundraising is already an incredibly trying process, the next stage is sometimes even more difficult.
In contrast, other friends & colleagues who've opted for the bootstrapped route (either by choice or circumstance) haven't seemed to face a similar massive amount of pressure. Yes, they faced incredible stress too, but not to the level of those that have raised capital.
This is merely an anecdotal observation made in my peer group. I don't mean to imply that this is some kind of phenomenon. And clinical depression is something that can cut through any kind of circumstance.
I just can't help but notice the stark difference in stress level of founders who are growing organically & carefully vs founders who are in a mad recruiting rush and sometimes hire the wrong kind of people. I wonder how much of a relationship there is between having the right kind of people in your company vs the wrong kind of people, and the stress level of a founder. I would imagine a lot.
