Cómo David consiguió clientes
Herramientas usadas para construir Sentry
David Cramer started Sentry as django-db-log in 2008. Five years of open source work led to product-market fit from day one when they launched the cloud service.
Sentry's origin isn't glamorous. In 2008, someone asked on IRC how to record errors to a dashboard. I gave them example code, created a repository, and django-db-log was born.
Over the years, I open sourced dozens of Django projects. At Disqus (joined 2010), we relied heavily on django-db-log. When I accidentally took down the entire platform my first week, the tool couldn't handle the error volume. That real-world use drove practical improvements.
Around Christmas 2012, Chris Jennings and I used our vacation to turn this into a business. We built multi-organization support, added Stripe billing, and launched on Heroku. Total time: about two weeks.
We launched and had our first paying customer that same day. Seven dollars. But here's the thing - we had product-market fit from day one because we'd spent half a decade building what developers actually needed.
The best thing you can do is find customers who share the same desired outcome you're passionate about. Build something you're passionate about, with a strong thesis around it. We never listened to potential customers who wanted something we disagreed with.
