What is Cairn?

Cairn is the finance operations platform built to give a business back its two scarcest resources — time and money. By pairing corporate cards with genuinely modern software for every dollar of non-payroll spend, Cairn turns the parts of finance people dread into work they barely notice.

Companies like Halewood, Applied Kite, and Copperline use Cairn to automate expenses, payments, accounting, and reporting. By closing their books 8 days faster each month and saving millions of dollars a year, they are building toward finance teams that stay small and stay strategic. The whole business moves quicker as a result.

Cairn’s finance operations platform saves time and money, so finance teams are freed from outdated tools and the processes built around them, and the company can put its attention back on the work only it can do. Cairn handles the rest.
