Cradle Bio B.V. (doing business as Cradle) is a Dutch–Swiss biotechnology company that develops software using machine learning for protein engineering. It was founded in 2021 and is based in Amsterdam, with an office in Zürich.[1][2]
History
Cradle was founded in 2021 by Stef van Grieken, Jelle Prins, Elise de Reus, Eli Bixby and Harmen van Rossum.[1] In November 2022 the company raised a €5.5 million seed round led by Index Ventures.[2] It raised a US$24 million Series A financing in November 2023, led by Index Ventures.[3] In 2024 the company announced a US$73 million Series B round led by IVP.[4][5]
Technology
According to TechCrunch, Cradle's platform applies techniques derived from large language models to generate amino‑acid sequence variants predicted to exhibit user‑selected properties (such as stability or binding).[1] Subsequent coverage reported use by pharmaceutical companies and performance improvements in protein design experiments.[6]
Recognition
Cradle was listed by Wired as one of the "Hottest Startups in Amsterdam in 2024" and was included in Bloomberg's "25 European Startups to Watch" list in 2025.[7][8]
