Airbase

Airbase is a San Francisco-based spend management company that provides mid-market companies with an integrated platform covering accounts payable bill payment, virtual and physical corporate cards, and employee expense reimbursements in a single system with a unified approval workflow. By consolidating these three previously separate processes, Airbase gives finance teams a complete view of all non-payroll company spending and enables consistent approval policies regardless of payment method. The platform's guided buying experience routes all purchase requests through the correct approvals before commitment, preventing unauthorized spend rather than catching it after the fact. Airbase serves mid-market technology companies and was acquired by Paylocity in 2023 for $325M, gaining access to Paylocity's customer base of HR and payroll software users. Prior to acquisition, Airbase raised over $130M from investors including Bain Capital Ventures and First Round Capital.
