Build Up Labs is a Lisbon-based venture studio and startup incubator backing and building early-stage digital product startups, with a focus on pre-seed B2B, SaaS, AI/software and internet companies. It supports founders from idea validation through MVP launch and scaling with incubation, mentorship, advisory support, networking, and access to investment. The firm is relevant for founders in Portugal and broader Europe seeking venture-studio or incubator support rather than a traditional standalone VC fund.
