Maya, founder of a small scheduling app

I run a seven-person SaaS company. I don't have time for books that take 300 pages to say what fits in a blog post. This one actually earns its length. Every chapter gave me something I could use — not theories, not motivation, but real, specific changes to our pricing page, our trial flow, and our cancellation sequence. I read it in three days and spent the fourth day fixing things. Our free-to-paid numbers are already moving in the right direction. If you sell anything online, just read it.
