$4m · Seed · Regenerative biomaterials · London, UK
Eterna Regeneratives, a King's College London spinout developing keratin-based materials for enamel and bone repair, has raised $4m in seed funding, jointly led by Hoxton Ventures and The Venture Collective. The company says the capital will move its platform from laboratory proof of concept towards products, expand its research and commercial teams, and support new partnerships. Its first focus is oral care, with bone-regeneration applications planned later. Read the company announcement.
Turning an enamel-like layer into a repeatable product
Eterna's platform uses peptides derived from sheep-wool keratin that self-assemble into an enamel-like layer. That shifts the problem from simply protecting damaged teeth towards rebuilding their mineral surface. For an oral-care partner, however, laboratory performance is only the first gate: the material must also fit a manufacturable formulation, a consistent supply chain and a credible route through product testing.
Starting with oral care narrows that commercialisation task before Eterna tackles bone regeneration. King's College London says the company is targeting early 2027 for commercialisation, so this seed round is principally translation capital: it funds the evidence, people and partnerships needed to turn a promising material into a product. Success in that first market could also de-risk the same platform for harder clinical applications later.
