Brian Halligan, founder and formerly CEO of Hubspot, has written A Startup Founder To Scaleup CEO’s Journey from $0 to $25 billion (Halliganism’s).
A bunch of short snippets (“Halliganism’s”) on founding and building a startup including leading, culture, team, strategy, decision making, crisis management, improving your CEO craft, managing yourself, exits, planning and stepping away.
This will likely be a classic, and it is only a long blog post and not a book like The Hard Things About Hard Things or a very long presentation like the original Netflix Culture: Freedom & Responsibility presentation (the 2024 version is a shorter document).
