I've been recommending these same books to founding teams for years. They're my go-to resources when partnerships hit rough patches or need stronger foundations. I'm such a fan that several of these authors have become mentors to me personally.
After seeing how much they've helped my clients as well, I realized this list shouldn't stay private. I've organized the list into four categories, with my absolute must-reads marked with a ⭐. The four categories span:
Co-Founder Relationships & Partnership Design,
Communication & Emotional Intelligence,
Startup Building & Strategy, and
Reflection Frameworks from Outside Startup World.
