About Sidemail

Sidemail is a 100% bootstrapped tiny startup made by two co-founders: @pkrupar & @k_vrbova. We’ve been making SaaS startups together since 2015 — our first startup Liftground is still around.

We do everything on our own without outside help. We learned everything about coding, design, and making software products in general from the internet — thank you, content creators!

When we needed Sidemail, it didn’t exist. Integrating transactional emails into an app felt like reinventing the wheel. To sent product updates, it was a nonstop struggle with unnecessarily complicated marketing tools. So in 2018, we challenged ourselves to fix that — build Sidemail. In the words of Ross Edgley, we were naive enough to start, stubborn enough to finish.

What’s beautiful about software products is that almost anybody can make a useful app in a small corner of the internet and make money — all you need is a laptop and an internet connection.

We’d love to keep working on Sidemail long-term and build a stable, profitable business out of what once was just a side-project.
