🥇 The Nugget: My Top Takeaway from A Conversation with Patrick Farrell
Founder burnout can kill a company too 🔥
We talk endlessly about grit and resilience in the startup sphere.
But Patrick flagged the dangers of grit gone wrong: founders that "sacrifice their soul" to build their company typically lose both.
From Patrick: "The spiritual and emotional health of the founder is so essential to whether the venture is successful or not. We could say, hey, it's all about resilience, it's all about grit. And those things are important, but wouldn't we rather be able to build ventures that are long-term sustainable, high growth, high ROI - AND the founder hasn't burned themselves out, ruined their relationships, broken up their family, and lost all their friendships throughout the process?"
Takeaway:
A founder’s health matters to the health of their startup.
Yes, it’s important to focus on finding “maniacs on a mission” (as Patrick O’Shaughnessy likes to say), and “healthy” can look wildly different for each founder and even for each season.
But as an investor, it’s worth being thoughtful about.
So next time you’re getting coffee with a founder, ask how THEY are doing, not just their business.
