Making Risk Decisions Worth Standing Behind

A team of risk scientists, engineers, and financial services operators building the infrastructure that makes AI-driven risk decisions trustworthy.

We Built This Because We Felt the Problem

The financial services industry makes millions of risk decisions every day. Most of those decisions are made by systems that cannot explain themselves, cannot be audited in real time, and were not designed with the compliance requirements of modern regulated environments in mind.

Prism Layer was founded in Chicago in 2024 to fix that. Our founding team came from financial institutions, risk analytics firms, and enterprise AI — and we had all watched the same failure mode play out: fast decisions, zero accountability, and regulators showing up later to ask questions nobody could answer.

We set out to build the reasoning infrastructure that makes AI risk decisions not just fast, but defensible. Every decision with a trace. Every model with a version. Every outcome with a reason code.

Built in Chicago, for a Reason

Chicago is home to the largest concentration of financial services infrastructure in the Midwest — trading firms, regional banks, insurance carriers, and fintech companies that process billions of dollars in risk decisions every year.

Building Prism Layer here means we are close to the customers who need what we are building, and we can hear their operational problems firsthand.
