CircuitHub

CircuitHub is a UK-based on-demand electronics manufacturing platform specialising in printed circuit board (PCB) fabrication and assembly. The company operates a digital manufacturing model, allowing hardware companies and engineers to upload designs and receive manufactured boards without the minimum-order volumes and lead-time commitments that traditional electronics contract manufacturers require. This makes CircuitHub particularly relevant to startups, research Teams and SMEs that need small-batch or prototype PCB production.

On 20 May 2026, CircuitHub raised $28m in a funding round led by Plural, the European deep-tech VC co-founded by Daniel Ek (Spotify) and others. The round positions CircuitHub to expand capacity and accelerate its on-demand manufacturing model into the defence, space and deep-tech hardware sectors, which are increasingly dependent on rapid prototyping cycles and domestic manufacturing sovereignty.

CircuitHub's growth reflects a structural shift in hardware development: as software-defined design tools have reduced PCB design barriers, the bottleneck has moved to physical fabrication and assembly at speed. The company's digital-manufacturing model addresses a gap that has been particularly acute for UK defence-tech SMEs needing domestic supply chains that do not depend on Asian contract manufacturers with long lead times. Plural's investment also signals that European deep-tech VCs are backing UK manufacturing infrastructure, not just software or AI.
