Connect AI to the system you actually ship
Tilia designs and integrates custom AI solutions (agentic workflows, MCP connectors, cloud architecture, and product enablement) at the core of your tools, teams, and business processes.
Let’s work togetherKeeping Human-in-the-loop
We build custom automations and partner with your teams to ensure smooth adoption: AI handles the preparation, humans make the decisions.
Fifteen years of web engineering behind your AI
Tilia is backed by Les-Tilleuls.coop, an 80-person worker cooperative, B Corp certified. We created FrankenPHP, API Platform and Mercure. Our members sit on the PHP and Symfony core teams, and on the PHP Foundation security team. We bring that engineering to AI: auditing your existing experiments, securing pipelines, and designing workflows that actually hold up in production.
Our solutions
We design intelligent applications that automate repetitive business processes, following a consistent principle: AI proposes and prepares, humans validate. Our offering is organized into six solution families, from strategic framing to infrastructure.

Measured, sector by sector
Every engagement is measured against three indicators: throughput, error reduction, and human time recovered. Not impressions.
