About eight years ago, I bootstrapped an application as a sole founder. About five years in with a pretty comfortable six-figure annual revenue, I wrote a book about that experience. Now, three years later, having just sold the application earlier this year, I'm starting on an overhauled second edition of my book. In the meantime, I've been publishing chapters from the first edition for free on Medium. There's about 30 chapters now with the rest coming over the next couple of weeks. Just realized it was something that folks here could probably benefit from. Hope it helps.
