Sperra .

Sperra is reimagining offshore construction through structurally efficient, low-carbon concrete products built for marine environments. We design and manufacture these products using ultra-lean, automated concrete printing technology that enables local, scalable production at ports worldwide. Sperra has raised over $26 million in non-dilutive grant funding to advance its product portfolio and build out its in-house manufacturing capabilities with 12 staff.

Our flagship product is a 3D-printed concrete anchor built for inland and nearshore floating solar. It’s low-carbon, cost-effective, and installs without heavy marine equipment - cutting costs by up to 50%. We have signed MoUs for over 305MW of FPV projects in the UK and are advancing pilot installations in 2025 in the US and Portugal to validate performance, obtain product certification, and support market entry.

Sperra is seeking equity investment to spin out its gravity anchor product line as part of a new Sperra subsidiary, Sperra Seaworks Limited.
