Software Engineer

About Caribou

International tax is a rigged system. Tax rules get ever more complicated, compliance gets more expensive, and the Big Four controls the expertise. They charge fees that only giant companies can afford, while smaller businesses are left flying blind.

Caribou is a tax platform designed to make international tax accessible to every global business. We’re fixing Transfer Pricing first, where one million businesses are in need, but only ten thousand experts exist.

Our backers include Y Combinator, Accel, Lakestar and angel investors who were founders or executives of leading companies in London and San Francisco.
