Sébastien Marchon is the founder and chief executive of Rydoo, the Belgian expense management company that now also processes supplier invoices. He started it in 2015 as a travel and expense platform with Sodexo as a shareholder.
Starting With Travel and Expense
Rydoo was born in 2015 as a travel and expense platform, with Sodexo as an early shareholder. Marchon had come from Sodexo’s own mobility and expense business. Early on the company bought two others: iAlbatros, which gave it a travel booking product, and Expenditure, which brought an expense management product.
Leaving Travel for Expense
In 2022 Marchon decided to leave travel and sell that business to CDS. He gave three reasons. Global coverage in travel requires integrations with local players country by country, travel needs services as well as technology, and the dependence on airlines, booking systems, and hotel aggregators limits speed. Rydoo has been profitable since 2023.
Revenue is now €35 million, up twelve times in ten years, with growth of more than 30% a year. The company serves 3,000 clients in 132 countries.
Expense Plus Invoices
Marchon talks about professional costs instead of expense reports, and about instant expensing instead of the end-of-month claim. In summer 2025 Rydoo bought Semine, a Norwegian accounts payable automation company, to cover invoices as well as expenses, and he positions the company as a platform for the office of the CFO covering expenses, invoices, and VAT recovery. He sees €100 million in revenue by 2029 as achievable.
Rydoo competes with Expensify on expense claims and with Spendesk on spend control, and he has chosen a different fight than the travel suites. His bet is that the finance chief wants one place for everything a company pays for.
