The Big Book of BrainDumps: How To Grow, Run and raise capital for your software business

What if you could shortcut years of painful trial and error with the hard-won wisdom of Business Software Founders who’ve already been to war?

How to Grow, Run, and Raise Capital for Your Software Business is your tactical field guide to building, scaling, and funding a successful B2B SaaS company. Curated by Chris Tottman (MessageLabs and Notion Capital), Richard Blundell, Paul Watson and Daisy Tottman, this isn’t another theory-heavy business book. It’s a raw, practical, battle-tested toolkit built around more than 70 visual ‘BrainDumps’ – frameworks that have racked up over 20 million impressions on LinkedIn and transformed how Founders think, pitch, lead, and grow.

Each BrainDump distils a critical startup concept into a punchy, one-page visual. But in this book, for the first time, they’re unpacked in full, with Founder commentary, investor psychology, and step-by-step guidance to apply them in your business.

Whether you’re stuck at $150k ARR or sprinting toward your Series A or way beyond, this book gives you the clarity, confidence, and tools to move faster. From defining your Value Proposition to crafting a killer Investor Deck, it’s all here – no fluff, no filler.

Loved by Founders, Operators, and Investors alike – this is the book every software CEO wishes they had when they started.
