At Rydoo, we make expense management simple, so people can focus on the important work, not their receipts. More than one million users trust us to submit, approve, and control expenses faster and smarter.
Semine shares that same mission. Since 2015, the team has been building AI technology that removes the repetitive, time-consuming parts of accounting, helping finance teams work smarter.
In July 2025, Semine joined forces with Rydoo to shape the future of financial automation. Together, we’re creating a complete, AI-powered platform that simplifies accounts payable and expense management, helping businesses run simpler, faster and smarter financial operations.
We’re a global team of +200 people who believe great tech should make life easier. If you have big ideas and want to build something that actually helps people, you’ll fit right in.
