About

AI still needs someone to put the company's data in order.

We started this because we kept running into the same problem. We had spent twenty years watching companies collect more data than ever, and still struggle to put much of it to use.

Why Filiament

We have spent our careers in the engine rooms of companies: building reporting platforms for finance teams, running and advising Private Equity-backed groups, leading engineering teams, heading data labs. In every one of them, the same thing: capable people spending their evenings reconciling figures by hand, in companies that had never collected so much data.

That frustration is where this company comes from. We think a company's data should be working for the people who run it. Not another dashboard to check or another tool to feed, but data that does its part quietly in the background, and that the agents arriving now can be trusted with.

We started Filiament because this problem sits exactly where our paths cross: entrepreneurs who have built and sold companies, engineers who ship and run platforms, operators who have lived the monthly close from the inside. It is the problem we know best, and the one we wanted to spend the next years on.

We model what is needed to operate.

Only that. A small model that people actually maintain is worth more than a complete one that nobody does.

We go one scope at a time.

Full deployments take time. We start with a narrow perimeter, get it running in production, then extend from there.

Engineers in the field.

The people who design the layer are the people who deploy it, in your systems, with your teams.
