Monumental Labs has secured $32 million in Series B funding, led by Khosla Ventures with participation from Plural and Hummingbird. This funding will support the expansion of their fleet of over 150 autonomous bricklaying robots across Europe and the UK, and fuel planned pilot projects in the US. The company's outcome-based service model, where contractors pay for completed walls, has already contributed to building over 100 homes and various other structures.
