Paragraf

Paragraf is the clearest proof that graphene can leave the lab and become volume-manufactured electronics, because it grows graphene contamination-free directly onto semiconductor wafers using standard chip-fab equipment — no flake transfer, no exotic line. That process breakthrough lets it ship the world's first commercially available graphene electronic devices, led by high-sensitivity Hall-effect magnetic-field sensors that outperform silicon and III-V rivals at cryogenic and extreme conditions and operate from microtesla to over 30 tesla. These aren't lab samples: Paragraf sells cryogenic Hall sensors and multi-sensor test units through an online store into quantum-computing systems, MRI, high-field magnets and scientific instruments — real markets that value stable, precise field measurement. The August 2025 $55M Series C — the largest graphene funding round of the year, led by UAE sovereign fund Mubadala with Amadeus, British Patient Capital and IQ Capital, pushing total funding above $60M — capitalized a dedicated graphene-electronics foundry near Cambridge (Huntingdon) built to serve high-volume demand. The roadmap extends beyond sensors to graphene field-effect transistors and biosensors, and a partnership with diagnostics firm TachMed points to graphene-powered medical devices at scale. Founder-led by Simon Thomas with Cambridge materials heavyweight Colin Humphreys, Paragraf owns the manufacturing moat that turns graphene from curiosity into a component line.
