About & Contact

Hi! I’m Roy Tomeij, and I’m an entrepreneur, speaker, teacher, and Jack of all trades from the Netherlands. To reach me, send an email or tweet @roy.


I’m co-founder of AppSignal, the leading European APM that provides insights into errors, performance issues, host metrics, and custom metrics for Ruby, Elixir, and Node.js applications.

In 2005 I co-founded 80beans (Amsterdam), one of the first Ruby consultancies in Europe. In 2013 we shut down 80beans after transitioning to working on AppSignal full-time.

Speaking & teaching

The best way to learn is by teaching. I have presented at many events all over the world, including notable ones such as Smashing Conference, RailsConf (thrice), SassConf (twice), Madison Ruby, Rocky Mountain Ruby, CSS Day, Feature of Web Apps, and CSS Summit. With topics ranging from front-end architecture and advanced Sass to neuromarketing for the web, I’m a Jack of all trades.
