Trala: Learn Violin
Learn violin with the Trala app!


Got skills but unsure where you fit? This is for you.

Trala is building a violin learning app that teaches anyone how to play the violin. The app listens to users play their real violins and gives instant feedback on every mistake.

This is a crazy-hard problem that requires us to solve new problems in signal processing, app design, user psychology, and education.

Our users are ages 7 to 70 and live in rural Montana, Syria, tiny Pacific islands, Hong Kong, and of course, Chicago. Yes, you can learn the world’s most difficult instrument via an app. Yes, we will teach you.

Why we work

  • Our users are people, not businesses or the government.

  • Our product is fulfilling these peoples’ lifelong dreams, and they let us know that.

  • We grew up in Techstars Chicago and now we’re generating revenue. Our investors include the CEOs of Linkedin and Duolingo.

The team

  • Sam: Violinist and engineer. Mastermind behind Trala’s musical pedagogy. Uses words like ‘pedagogy’.

  • Vish: Can code anything. Winner of 4 national hackathons. Has eaten a Death Sandwich and survived.

  • Lauren: Professional artist - not starving. Like Ram Dass and Frank Gehry combined. Has been compared to a ball of floating light.

  • Joel: Attempting to unseat Vish. If transported to the middle ages would use knowledge of modern medicine to improve lives of peasants. The Muhammad Ali of Connect 4.

  • Chen: Visual designer. Fashionable, like all good visual designers. Looking at her designs is like getting winked at by your celebrity crush.

  • Josh: Senior software engineer. Was on a submarine for 10 years. They finally let him off but occasionally we see a periscope out of the corner of our eye and he ducks under a table. Currently rebuilding the Hagia Sophia with napkins.

  • Jon: Software engineer. Jazz piano player of 16 years but he might be lying about that. Picks up new instruments like Josh picks up napkins.

  • Jennifer: Head of growth. Started and sold a startup back in the day. Said it was “easy”.

  • Geoff: Pro violinist. In four bands. Or five. It’s hard to keep track.

  • Rachael: Pro violinist. Probably played at that white-tie gala we weren’t invited to.

  • Llama: Where the fuck did the llama come from? Why does it keep staring at me? Play it cool.

  • You: Shrouded in mystery (for now).


  • Competitive compensation package.

  • Work in downtown Chicago. Great working space, free coffee, etc., we’re a startup.

  • Never eat lunch alone: Trala is a family. If the mob comes looking for you we will hide you in the ceiling.

  • Our mentors are leaders in growth and app monetization. They will be your mentors, too.
