Small bets.
Sharp edges.

New interfaces, AI-native tools and weird little internet ideas. Some become products. All of them teach us something.

Antoine Alejandro, founder of Tense Lyrebird
Antoine AlejandroFounder / Builder

I’m Antoine—web technologist, product builder and persistent question-asker.

Years as an expatriate in Hong Kong shaped how I see speed, culture and possibility. Now back in France, I work across borders with founders and teams who want technology to do more than simply function.

Tense Lyrebird is both my freelance studio and the home of my own product experiments: a deliberately small company with room for big range.
