I've met hundreds, maybe thousands of people while doing this. And it wasn't possible without the help of a lot of people.
I'd like to thank every person who ever used my apps and websites, especially those who supported me financially by becoming a paying customer.
This way of building a company is called "bootstrapped". Because the goal of a bootstrapped business is much more reachable. You're already there if you can pay yourself enough to live from. You'll probably have less stress, be happier and be therefore a better friend, lover, partner or parent. The coolest thing about bootstrapping it is that it doesn't exclude "going big" later.
The last years were a whirlwind of adventures while building all these products and being part of the startup ecosystem.
Writing a book on it with a proven framework people can apply, may help accelerate this change.
There's a personal legacy aspect here: if I can have a small influence in changing this, it feels good as a person. And if it doesn't, well, thousands of people paid me money for this book, so it's a nice backup for me in case I go bankrupt.
And keeping me grounded as a human by being consistently unimpressed and laughing at my internet celebness.
I'd like to thank Product Hunt, and specifically Ryan Hoover and Andreas Klinger for always supporting me, giving great feedback and highlighting my startups repeatedly. I have to be honest to say I hardly read books myself.
