Concourse

Founding AI & ML Engineer

New York, NY

Concourse builds AI agents for corporate finance teams. Companies connect core data sources from data warehouses, ERPs, payroll, billing, and more into Concourse, where our AI agents can analyze data and deliver insights in seconds. Our AI agents can be prompted through natural language and can return analyses, forecasts, and reports, boosting the finance team’s productivity by up to 10x. Purpose-built for finance, Concourse agents offer auditability, memory, and presentation-ready output, helping teams cut manual work by 75% while generating 6x more insights.

At its core, Concourse is reimagining how companies interact with financial data. Traditional finance tools haven’t changed in decades, teams still rely on fragmented point solutions and static spreadsheets. Our mission is not only to automate routine tasks but to transform decision-making by giving finance teams a deeper understanding and generating net-new insights into business performance.

Since launching less than a year ago, Concourse has grown rapidly. Our AI agents are deployed across 50+ customers, including unicorn startups (Persona, Front, Lightmatter) and large public companies (including a Fortune 500). Concourse is a Y Combinator company backed by Andreessen Horowitz, CRV, and 50+ angel investors from companies like Brex, Rippling, Flywire, and DoorDash.
