What Philippe brings to Certo

3 reasons Philippe makes Certo stronger

Philippe trained in applied mathematics at ENSTA Paris and data science at École Polytechnique. He started as a data scientist at AXA Climate and Metric Arts in Santiago, then spent five years at Kili Technology, growing from data scientist to squad and technical lead as daily usage went from a handful of users to more than 500.

As senior tech lead at DeepIP he took a product from a 21-day proof of concept to 4M ARR in two years. Most recently he was founding engineer at Phacet, building auditable AI agents that structure, reconcile and control finance data for 100 clients in production.

Auditable AI

01

Agents you can trust

At Phacet he built AI agents for finance data with full auditability at every step. Certo’s checks hold the same bar: every verdict traceable to its source.

Zero to scale

02

Ships fast, without cutting corners

Two releases a week, complete CI/CD and full observability from day one: the habits that took DeepIP from POC to 4M ARR now shape how Certo ships.

Enterprise-ready

03

Sensitive data, handled right

From on-premise installs for enterprise customers at Kili to LLM integration with sensitive data and compliance constraints at DeepIP, he builds for the security bar large brands expect.
