I bought a side project back in 2014 (3-4 month old then with about $2000 MRR) and grew it to a bootstrapped SAAS company of 20 employees as of today with revenue in 100K MRR range. Happy to answer any questions.
That's an interesting pair of statistics. Part time employees? Outside the US? A business that is heavy on inexpensive support personnel and light on engineering?
And if you had to do it over again would you buy the business again or did it change dramatically enough that you'd try to create it from scratch next time?
