Why we created the HAT

Generic solutions imposed concrete limits on what we wanted to achieve for our clients.

  • We wanted to build sustainable digital environments, capable of evolving with needs without becoming bloated.


    So we created a system in our image: a performant and economical serverless AWS architecture, open and integrable. Designed to expose and share data fluidly, including for emerging practices in the AI era, including AEO.
