Lightbringer, the Malmö-based AI-powered legal technology company transforming how startups and SMEs secure patents, has raised €8.6 million ($10 million) in Series A funding.
The round was co-led by London-based 6 Degrees Capital and Amsterdam-based Newion, alongside existing investors Luminar Ventures and Alliance VC. Thomas Olszewski, Partner at 6 Degrees Capital, and Dorus Olgers, Partner at Newion, have joined the Lightbringer board.
In Q2 2026, the company reported 300% revenue growth year-over-year following its rapid customer adoption across Europe. To build on this success, Lightbringer will use the funding to fuel its expansion into the U.S., while enabling further development of its AI-powered patent platform for growing deep tech companies. The U.S. represents the world’s largest and most competitive market for intellectual property (IP), and a key priority for Lightbringer’s next stage of growth. Its Service as Software (SaS) offering combines IP strategy, patent filing, and portfolio management all in one place, automating processes that have traditionally relied on costly and time-consuming work by external law firms.
“Protecting an invention still means weeks of back-and-forth with a law firm, unpredictable hourly billing, and surprise invoices. Most AI in this space just makes lawyers slightly faster. We built something different: an AI-native platform that handles the patent process directly for technology companies. Powerful agentic models do the work, with expert attorneys stepping in where judgment matters.”
says Dominic Davies, CEO and co-founder
Until now, AI software in the patent sector has focused on building better tools for lawyers – streamlining workflows, reducing admin, and cutting billable hours at the margins. Lightbringer takes a fundamentally different approach. It is an AI platform designed to replace existing patent firms, not assist them.
“We are building the best patent service platform in the world from first principles with focus on helping tech company leaders and innovators protect their technology and business opportunities.”
says Markus Andreasson, CTO and co-founder
Founded in 2023, Lightbringer combines agentic AI with the oversight of expert patent lawyers, reducing typical patent filing timelines from two months to just a couple of days, cutting costs by around 50% through its fixed-price subscription model. Since its rollout in 2024, Lightbringer has helped more than 200 deep tech companies, across 17 countries, file and manage their patents globally including: critical infrastructure hardware specialist TERASi, defense drone component company ARCTIC RAVN, quantum sensing technology developer DIASENSE, and Cler, the Swedish clean-air technology company.
As of 2025, the global IP legal services market is valued at approximately €14.8 billion, yet many innovative companies still fail to capture and protect the full value of their IP due to slow, expensive, and inaccessible patent processes. This outdated model – heavily reliant on manual collaboration between technical teams and legal specialists – creates significant barriers between innovation and business protection. Compounding this issue, there is a global shortage of patent lawyers working across highly specialized technical fields – such as quantum computing, novel materials, or advanced AI architectures – and non-technical patent lawyers often struggle to fully grasp the nuances of the inventions they are being asked to protect.
For technology companies operating in highly competitive sectors, these inefficiencies can have far-reaching consequences. Valuable inventions may remain unprotected resulting in lost opportunities to attract investment, secure market share, and maximize growth. In many cases, the greatest risk is not the cost of filing patents, but the strategic IP that is never protected in the first place. Lightbringer’s AI, by contrast, can rapidly develop deep domain expertise in fields with knowledge deficits, making it well-suited to understanding and articulating the technical substance of a patent application.
