Mathieu Kempé

Co-Founder & CTO at Cogentic  ·  Sydney, Australia  ·  AI agents for onchain compliance


What I'm Building

AI agents for onchain financial crime compliance. They triage alert queues, run investigations and draft regulator-ready SAR, SMR and STR filings inside the stack a compliance team already runs. Every brief cites its sources and lands in an immutable evidence ledger.


Stack

Now TypeScript end to end, React and Next.js, Postgres, containerised services, CI/CD.

Agents Multi-agent orchestration on Mastra. Production agents, under test, fully traceable, and not tied to a single model provider.

Before .NET and C#, relational and document databases, cloud platforms, distributed systems, multi-tenant SaaS.

Commerce Seventeen years in ecommerce and marketplace platforms. Full commerce stack, merchant-facing products, payments.

Leading Building and scaling engineering organisations to 35+. Engineering and technology management, cross-functional leadership, hiring, mentoring, growing engineers into leaders. Stakeholder management at executive and board level.


The Short Version

Twenty-four years. Started on .NET in France, writing systems for Alcatel, Bouygues Telecom and PSA. Moved to Sydney and built one of the first Silverlight sites in Australia, for Discovery Channel.

Co-founded Selz, a direct-to-consumer commerce platform, and grew it to 30,000+ live merchants before Amazon acquired it in 2021. Stayed on at Amazon for four and a half years as Sr. Manager, Software Engineering, running a multi-team org across Australia and the US. Before that, Technical Director at Community Engine, scaling engineering to 35+ people.

Microsoft MVP. DESS in Computer Science, a French postgraduate diploma roughly equivalent to an MSc. Studied neural networks in 2003 and somehow ended up building agent tooling in 2026. English and French.

Still building things outside work.
