Airbase needs high paid conversion rates
Airbase
This choice turns Airbase into a software monetization bet, not a card economics bet. By giving most interchange back as cashback, Airbase uses the card to win attention, then has to make money when a finance team decides the workflow is valuable enough to buy. That only works if free users convert into paid plans at unusually high rates, because rivals like Brex and Ramp can fund free software directly from card spend.

Airbase sells annual software contracts of roughly $42,000 to $230,000 across Standard, Premium, and Enterprise tiers. That means a converted customer can be worth far more than card rewards alone, but only after Airbase has proven enough control, approvals, and ERP integration to justify a real budget line.

In this category, cashback has become a customer acquisition tool more than a durable moat. Nearby spend platforms describe card rewards as commoditized, with the lasting value coming from the system that handles request, approve, pay, and reconcile across cards, bills, and accounting.

The broader market has already shifted away from judging these companies on payment volume alone. Ramp and Brex have both moved toward higher margin software and broader finance workflows, which reinforces why Airbase needs paid software attachment, not just card usage, to make its model work.
Going forward, the winners in spend management will be the companies that turn payment activity into deeply embedded finance software. Airbase is positioned for that path because it already targets more complex mid-market customers, but the payoff will come from converting those users into larger, stickier workflow subscriptions that sit at the center of how companies approve and move money.
