Lightbringer, a Malmö-based legal technology startup focused on patent services, has raised $10 million in a Series A funding round co-led by 6 Degrees Capital and Newion, with participation from existing investors Luminar Ventures and Alliance VC. The company develops AI-powered software for patent drafting, filing, and portfolio management, targeting startups and small-to-medium-sized businesses. Lightbringer will use the new capital to support its expansion into the US market and continue developing its patent platform.
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 US, while enabling further development of its AI-powered patent platform for growing deep tech companies. 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.
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.
Dominic Davies, CEO and co-founder of Lightbringer: “Intellectual property has become one of the most powerful assets a deep tech company can have. In a hyper-competitive market, the speed at which an inventor can file a patent application on their innovation can mean the difference between a company’s success and demise. As a patent lawyer, I’ve seen firsthand how the global patent system is not built for startups or the modern business environment. Most legal AI helps law firms become more efficient and protect their margins. We built Lightbringer to do the opposite: take on Big Law and return that value to entrepreneurs. This funding allows us to accelerate product development, deepen our US presence, with me relocating to lead our operations there.”
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, defence drone component company Arctic Ravn, quantum sensing technology developer DIASENSE, and Cler, the Swedish clean-air technology company.
As of 2025, the global intellectual property (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 specialised 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.
Thomas Olszewski, Partner at 6 Degrees Capital: “Lightbringer is solving a major structural problem in the global innovation ecosystem. The patent industry still runs on workflows and business models designed decades ago, so many founders either delay protecting their innovations or skip the process altogether. What Lightbringer has built is not simply a more efficient law firm, but an entirely new category of AI-native intellectual property infrastructure.”
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 maximise 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.
Dorus Olgers, Partner at Newion: “Lightbringer has demonstrated exceptional traction in a short period of time by building a platform that delivers clear and immediate value to founders, engineers, and innovation-led businesses. Lightbringer believes IP protection should be accessible to everyone, something that is not the case under today’s market conditions, and has built a platform that helps make that vision a reality. What sets the team apart is how quickly they’ve turned deep legal and technical expertise into a product founders actually adopt. We are excited to support the team as they continue expanding internationally and establish Lightbringer as a leading platform for modern patent development and strategy.”
