About

Behind GLILAB, 16 years of mobile apps.

GLILAB is a mobile and web development studio founded in 2017 by Jérémy Roustang, senior developer since 2010. We design, build and ship apps for our clients, and we publish our own.

The founder. Jérémy Roustang, lead mobile developer.

Trained at SUPINFO, Jérémy has been building mobile apps since 2010. He first ran the mobile department of Cardinalis until 2017, where he built Raidigma, an iOS and Android app of city tours with games and quizzes.

Since 2017 he has built the apps of large retailers and startups: Sarenza and Vibs for Groupe Beaumanoir, M' Monoprix and Monop'Hop for Monoprix, klood, GeoWallet, CoWork.io and HR Proximity.

Alongside that work, the studio designs and publishes its own apps, from the idea to production: design, development, back end, subscriptions and updates.
