The parallel run

Don't trust us.
Reconcile us.

We run in parallel with your current system, on your real books. You define the criteria we reconcile to, and we hit them or we don't. You cut over when your own numbers say so.

General purpose AI is becoming a commodity. Any workflow you can describe in a prompt can be replicated by a general model. The software that survives this shift won't be a wrapper. It will be the system of record that runs the work.

These industries are hard for real reasons. The rules are unforgiving. The data is proprietary and messy. The financial logic is specific to the work, learned over decades. The cost of getting it wrong is measured in millions. That difficulty is exactly why software built for easier problems has passed them by, and exactly why they are worth building for.

VectorOne is built for them: deliberately, one industry at a time, on a shared foundation that each new industry starts from.

Six industries

An AFE is not an invoice.
A loss triangle
is not a ledger.

Each industry gets its own system, built around its own documents and its own rules. All six run on the same shared core.
