Cohort analysis is super important if you want to know if your service is in fact a leaky bucket despite nice growth of absolute numbers. There’s a good write up on that subject “Cohorts, Retention, Churn, ARPU” by Matt Johnson. So how to do it using R and how to visualize it. Inspired by examples …
Entrepreneurs, such as Illya Segalovich (co-founder of Yandex), Loic LeMeur (founder of Seesmic and LeWeb), Peter Arvai (co-founder of Prezi) and many others (see full list on the book’s website: www.europeanfoundersatwork.com) tell about how they started, built, pivoted and drove their businesses to success.
The book gives a unique first-hand perspective on how to grow a successful business from Europe, what is the importance of US market, what are the challenges European start-ups are facing and what are the competitive advantages of being in Europe.
It is an inspiring book, and it is very relevant to European entrepreneurs. While stories of US start-ups quite often start with “we got $N mln in funding and started growing from there”, in Europe it’s more about bootstrapping and building a profit-generating machine. I would definitely recommend it to anyone who is thinking of starting a technology company in Europe or is already running one.
