Introducing Lightbringer
Lightbringer built an AI-native patent platform. However, rather than selling software to patent law firms, it is a software company that operates as a law firm. Lightbringer combines artificial intelligence with human attorneys to deliver a full service: drafting, filing, prosecuting, and managing patents for companies that need IP protection. Being AI-native enables it to deliver a better outcome, faster, and cheaper.
The market Lightbringer targets is large and structurally stuck. Some 3.7 million patent applications are filed each year, more than 10,000 per day. Ironically, while the industry exists to support innovation, the patent protection process itself has changed very little. It is provided by firms that bill by the hour and are effectively rewarded for inefficiency. These traditional law firms cannot introduce automation without cutting partner income, making it difficult to sell them AI-native patent software.
Lightbringer bypasses the traditional law firms and goes directly to the end customers, competing for the much larger legal budgets of those customers rather than the modest software budget within law firms. The platform spans the entire patent lifecycle, from idea capture and existing patent search, to drafting, filing, and prosecution.
Customers simply upload engineering documents, after which Lightbringer’s AI extracts the technical details, builds a structured knowledge graph, and asks tailored follow-up questions. This initial self-serve step is free and provides a compelling entry point for the customer. For Lightbringer, it is a scalable, product-led customer acquisition channel.
Customers can then proceed to the paid full-service offering. An AI agent with the complete patent-attorney toolset reads, drafts, edits, and comments on applications. Crucially, Lightbringer operates a human-in-the-loop model. In-house Lightbringer attorneys review and validate AI-generated output prior to submission, but because they no longer need to conduct the research or draft from scratch, the time required to file a patent is reduced by more than 80% and the cost is halved.
Finally, the platform is used by customers to manage their portfolio of patents and automatically flags new competing patents as they are published.
Strong early traction
In Q2 2026, the company reported 4x revenue growth year-over-year following its rapid customer adoption across Europe. Customers subscribe annually per patent application, and because a patent journey typically runs three to five years, revenues are long duration. Revenue per customer also expands over time, with deep-tech companies often filing multiple patents, resulting in strong net revenue retention.
The customer base is diversified, spanning technology, medtech, cleantech, biotech, defence, and aerospace, which supports the view that AI-native drafting does not require sector-specialist firms. Customer acquisition is led by founder led sales and the free product tier, which together produce sales cycles as short as 1-2 days.
A large market and a clear path to scale
IP-focused law firms such as Fish & Richardson generate more than $500m in annual revenues with approximately 400 attorneys operating under the traditional model. Lightbringer should be able to generate equally meaningful revenues while achieving substantially higher profitability through AI-driven automation.
The wedge into the market is real, the momentum is strong, the product is perceived as exceptional, and the growth targets remain modest relative to a market where 3.7 million patent applications are filed every year.
A team that has lived the problem
The team is experienced and combines deep patent expertise with a track record of building and scaling companies:
Dominic Davies (CEO) is a UK and European patent attorney who has filed more than 200 patents and previously ran his own IP consultancy firm. He is also a trained software engineer, and this rare combination of patent law and engineering sits at the heart of the company’s edge. Dominic is deeply passionate and considers Lightbringer his life’s work.
Ola Wassvik (CCO) was co-founder and CTO of FlatFrog, which raised €80m+ in venture capital before being acquired by CVTE Group. Ola has filed 330 patents across 30 countries and brings first-hand empathy for the customer’s patent pain.
Markus Andreasson (CTO) is a platform architect and AI engineer who has worked with Ola across three ventures. He leads the engineering team in Sweden.
Round
6DC co-led Lightbringer’s $10m Series A alongside Newion. The capital will fund the US expansion and the continued scaling in Europe. Existing investors include Nordic funds Alliance and Luminar, both of whom invested further in this round.
