Here's Why
> But I built the first version of Storemapper from nothing to live-and-accepting-payments in one 30-hour flight
He launched his MVP within 3 days.
> I charged for Storemapper from the beginning (just $5/month) and gradually raised prices and added plan tiers over time. The first 5 customers came from just emailing every client I ever had about Storemapper.
Instantly validated MVP by charging from the beginning, and by getting PAYING customers from Day 1.
> I never put any money into Storemapper. It was cashflow positive the entire time, mostly because I stacked my SaaS business on top of a lot of other SaaS products that typically had a free or very cheap starting tier, so costs grew linearly with revenue
Most of all, this. Didn't sink money into the idea hoping it would click. Instead, saw a need, built the MVP in 3 days, launched it, started charging from day 1, and got paying customers from day 1.
