I finished writing Founder Unfriendly in August of last year. Between then and now, something changed.

Not the fundamentals of fundraising — those haven't moved. What changed is the toolset you're working with. When I was writing the book, AI was a novelty you could use to draft an email or generate a first pass at something. It wasn't yet a real thought partner, a research engine, or a working prototype machine.

It is now.

The analysis in the book stands. The self-assessment questions, the investor psychology, the pitch mechanics — all of it. But there's a layer of practical acceleration available to founders today that simply didn't exist in the version of the world I was writing for. This companion guide adds that layer.

The goal isn't to replace the book. It's to help you use the book faster, go deeper on the parts that matter most to you, and build things you used to need a team or a budget to build.

A note on tools: Claude does everything in this guide pretty well — research, writing, simulation, analysis, pitch prep. Some tools have specific advantages for specific tasks (Granola for meeting transcription, NotebookLM for synthesizing large document sets, Lovable for building apps), and we'll call those out where they matter. But for the core exercises, Claude handles it all. More importantly, if you use Claude consistently across every exercise, it builds context about your startup over time — your stage, your market, your investors, your thinking. That compounding knowledge makes every subsequent prompt smarter. If you have a tool you prefer, use it. But if you're starting from scratch, just use Claude.

What's in the book

CH1
Free Your Mind
Why the first thing you need to do before raising has nothing to do with your deck. There's one exercise in this chapter most founders skip — and it's the most important one.
CH2
Show Me the Money
The most-quoted stat about who gets funded is off by nearly 10x — and understanding why changes how you read every number you'll ever hear about venture. Including the ones investors will throw at you in a meeting.
CH3
I'm Putting Together a Team
The best early-stage companies don't look like companies. They look like something else entirely — and building that thing starts before you have a dollar of funding or a single employee.
CH4
You Can't Handle the Truth
The applause you get when you launch is the most dangerous moment in your company's early life. Charlie explains exactly why — and what real signal actually looks like.
CH5
There's No Crying in Baseball
Only once in 20 years did Charlie see a first-time founder get a yes from every investor she pitched. The chapter breaks down what she did that almost no one else does. It's not what you think.
CH6
Keep Your Friends Close
Investors don't trust pitch decks. They trust founders. There's a specific reason why most founders lose that trust before they've finished presenting — and it has nothing to do with their numbers.
CH7
To Infinity... and Beyond!
When an investor asks how much you're raising, most founders answer the wrong question. The right way to build your number is explained here — and it has nothing to do with how long your runway is.
CH8
Sell Me This Pen
Not all investor money is the same — and the wrong money is worse than no money. Charlie maps the investor landscape in a way that will change who you approach and how.
CH9
These Are Not the Droids You're Looking For
According to DocSend, only about a third of pitch decks ever get opened. The chapter explains what determines whether yours is one of them — and it's not the deck.
CH10
Dogs and Cats, Living Together
"Interested" is the most dangerous word a founder can hear from an investor. The chapter explains what it actually means — and what real momentum looks like instead.
