Hear from Our Team
Connection & Community
We believe in having fun, and creating unique moments with our team.
We also regularly host AI communities in our office. We built Tessl HQ to be a hub for learning and collaboration in the London AI scene, especially for developers and builders working in the AI-native world.
How We Work
Our Operating Principles
Embrace the Pace
Move fast, ship early, and learn in public
Build, then Break
Nurture ideas first — then pressure-test them together.
Grab a Shovel
Step in, get scrappy, and make progress even when it’s messy.
Be AI Native
Use agents daily and share what works (and what doesn’t).
Own It
Make ownership clear, decide quickly, and back the outcome as one team.
Where we work
We are headquartered in Kings Cross, the heart of London's tech hub. We work hybrid, with anchor days in the office on Monday, Tuesday and Thursday. Those days are intentionally for deep, fast collaboration - pairing, design sessions, working through problems together, and spending time as a team. We believe that in-person working is a pre-requisite for building a strong culture and making work fun.
