Built by people who have worked insidethe workflows they automate.

We are an applied AI lab for financial institutions. We build AI that takes on the operational work between a firm’s systems, inside the firm’s own environment and under its own controls.

Why we started

The work that keeps a firm running is still done by hand.

With more than a decade of experience at Wall Street banks between us, we kept running into the same thing. That story repeats at every firm we talk to. Operations runs on messages: a chat from a counterparty, a custodian statement, a spreadsheet that changed shape last week. People move that information between systems by hand, and every handoff is a place where money and time leak out.

What we build

AI built around how your firm actually works.

We build for the firms we work with, and the workflows we cover keep expanding with every desk we sit on. Trade capture was first, and today we have workflows including allocations, reconciliation, pre-trade and venue controls, exception management, settlements, confirmations, enterprise blotter, KYC and account openings, compliance and regulatory records, data transfer, email processing, and reporting. Each new deployment adds another, so the next firm starts from a longer list than the last.

Sellara reads what comes in, investigates what needs to be done, and executes the work. Your rules and your approvals decide what actually happens, and every step is recorded.

How we work

Forward deployed, starting with one workflow.

We work inside your systems, not next to them. We start with one workflow, get it live in weeks, and add the next one from there. Our team sits with your operations staff while we build it, and we stay with it after it ships.

The team

Two of us came from Wall Street desks. Two of us have shipped AI into production.
