Lightbringer has raised $10 million in a Series A co-led by 6 Degrees Capital and Newion to expand into the US.
The Swedish AI patent platform reported 300% year-over-year revenue growth in Q2 2026 and serves more than 200 deep tech companies across 17 countries.
Unlike most legal AI tools, Lightbringer aims to replace traditional patent firms entirely, cutting filing times from two months to a few days at half the cost.
Most deep tech startups build innovations that could reshape industries, then spend months waiting to protect them. The patent system, designed for a different era, treats speed as a luxury. Lightbringer was founded by people who built that system and decided it needed to be rebuilt from scratch.
The Swedish company has raised $10 million in a Series A co-led by London-based 6 Degrees Capital and Amsterdam-based Newion, building on its seed round led by Luminar Ventures and Alliance VC in late 2024. The capital will support product development, US market entry, and the relocation of CEO Dominic Davies to lead American expansion.
