Capgemini Invent vs ITRex Group: overview

Capgemini Invent

Capgemini Invent launched in 2018 as the digital innovation, consulting, and transformation brand of the broader Capgemini Group, headquartered in Paris.

It combines strategy consulting with data science and creative design under one brand, positioning generative AI work as part of a broader digital transformation practice rather than a standalone specialty.

ITRex Group

ITRex has been based in Southern California since 2009, and public headcount estimates range from around 221 up to over 250 employees across three continents.
