Koen Christiaens

Koen Christiaens built his reputation as a product-first founder at Xpenditure and Rydoo, the Belgian expense management stack he co-founded alongside Boris Bogaert and other operators from the Massive Media / Netlog orbit.

He started with Cardwise, a digital card and expense startup, then co-founded Xpenditure, which grew to over 10,000 B2B customers before being rebranded as Rydoo. At Rydoo, Koen served as both Chief Product Officer and co-founder, helping scale the platform to more than one million users across the world. Sodexo Group acquired Rydoo in March 2017.

After the exit, Koen co-founded Pitchdrive in 2020 alongside Boris Bogaert and Wim Derkinderen. The fund was initially built from a syndicate of Belgian angels drawn from the Netlog/Twoo/StarApps founder generation. Pitchdrive closed its third fund at EUR 40M in 2024. Koen also serves as an Entrepreneur-in-Residence at Smartfin.

He is an angel investor and board member in more than 20 startups, with a focus on sales, marketing, and partnerships-driven growth.

Koen brings a strong product lens to Pitchdrive's portfolio, with a consistent focus on the go-to-market and product-market fit questions that determine early survival for B2B SaaS companies. He is described as a "product guru" in the Belgian ecosystem.
