I've met at least 10 people who are building a new dating app in the last 3 years. I'm quite aware that it's almost impossible to pull it off. This book describes the journey of a founder who launched his datings apps and was quite successful with it until he wasn't.
Cliff followed all the best advice and practice I'm aware off and still found it challenging. It just shows how brutal the market is. Particularly I liked his focus on innovation, experimentation and data driven approach.
The book is an easy and engaging read. There are plenty of lessons for any entrepreneur.
