My name is Peter Theill. I’m a 40+ year old software developer currently working as CTO at my own startup Familio. I started coding way back in 1987 on a good old C64 and got more serious around 1994 where some of my first shareware products were released.

I finished my education as a Datamatician in 1998 and immediately joined Belle Systems as a Software Developer. It was an exciting time joining a company as employee #24 and over the next four year growing it to 500+ employees (and then down to ~200). It was the dot com days 🙂

While working at Belle Systems, a colleague and I decided to build a site for shareware authors. A couple of sites already existed by they were all badly designed, had lots of advertisements and did not provide a lot of value for the software authors. We named it Filebasket and grew it quickly to 200k+ users before it was acquired by Digital River.

I decided to leave Belle Systems (now called Digiquant) in 2002 to study Computer Science while doing consultancy for Digiquant but also other customers, primarily working with the .NET platform.

A cool startup called ZYB contacted me and I decided to join as their second backend developer. It was an insane ride where I got to work with extreme talent until we got acquired by Vodafone. At that time I decided to leave to start a company called Gazebo with a couple of colleagues.

Gazebo helped other startups build a prototype of their idea in weeks so they were able to present something for investors. A couple of companies we helped are Rojabo and Biokemi.

Even though Gazebo was quite successful we decided to throttle down after only one year of operation since we, the founders, did not fully agree in which direction we wanted to move the company.

I did some consultancy work until I joined GoMore. I rebuild the technology stack from a 8+ year old system and took it from 15k to 90+ users in 1.5 year.

In 2011 I joined Click A Taxi, later rebranded into Drivr as a co-founder. It was a fun ride where we pivoted a couple of times but in the end had to close down in 2017.

After a couple of months thinking about what to do next I joined Familio.
