UK Startups and Innovation: Humanoid's buyers wrote the $152m chequeBackground
Prime Movers Lab is a US venture capital fund investing in deep-tech and frontier-Science companies, backing hardware-intensive ventures that require patient, technically literate capital rather than pure software plays.
Leading Humanoid's Series A placed the fund at the centre of a financing structure in which the company's own industrial customers, Schaeffler and Bosch, also took equity, a structure increasingly common in European robotics rounds where established manufacturers want both a stake and a supply relationship in the companies they back.
The fund's involvement signals continuing US capital appetite for European deep-tech, even as UK observers debate whether foreign or domestic investors are now setting the price on the country's most valuable robotics bets.
