Malmö-based AI security startup Oplane has secured €4.5 million in seed funding in a round led by Seed Capital, with participation from existing investor Icebreaker.vc and angel investors including Emil Eifrem, Robert Lagerström, and Joakim Nydrén. The company develops an automated security architecture platform that helps engineering teams identify and address security risks as software is built using AI coding tools. The company plans to use the funding to expand its commercial operations in Europe, add integrations with AI coding tools such as Claude Code, Cursor, and GitHub Copilot, and hire across engineering, cybersecurity, QA, and go-to-market functions.
Oplane is an agentic security platform for AI coding teams founded by Emil Kvarnhammar, Oscar Andersson, and Anders Söderling. Using expert-level threat modeling, the solution automatically maps codebase architecture, identifies system-level security requirements, and delivers contextual remediations directly into developer workflows. Oplane was founded in 2022 and is headquartered in Malmö, Sweden.
“We work with some of the fastest moving companies in AI today. Almost everyone is adopting AI coding tools, whether we talk to Enterprise, Big Tech or AI hypergrowth companies. They’re not just shipping faster, they’re accumulating architectural risk at the same speed. AI coding tools are optimised to solve the immediate problem in front of them – not for security. Anthropic, OpenAI and established cybersecurity players are active in our domain – still, our customers choose Oplane. I’ve spent years trying to solve this problem consistently at scale with human capacity, it is impossible. It needs to be addressed with agentic solutions, tightly embedded with an organization’s development workflow. Secure Development Lifecycle is no longer a dream, and Oplane is becoming a category leader,” states Emil Kvarnhammar, Co-founder and CEO, Oplane.
When code is written, refactored, and deployed at machine speed, human-led security reviews, manual threat modeling, and architectural sign-offs are physically impossible to execute. Unlike legacy tools that react to vulnerabilities after deployment, Oplane embeds security-by-design directly into the agentic workflow. Meaning the platform provides real-time asset graphs and automated remediations. It secures the intent before it becomes risk, ensuring AI-generated architectures are resilient by default.
The rise of vibe coding has moved from side projects into the core of enterprise engineering workflows, and the pace at which architectural risk accumulates has matched the pace at which teams build.
Oplane is already deployed in production at Miro and Tandem Health, where adoption has scaled from a handful of repositories to several hundred, with thousands of threat models run in a matter of months. A handful of additional pilots are active with further customer announcements expected in the coming weeks
Copenhagen-based Seed Capital is leading the seed round.
“The Oplane team is on a mission to make secure software the default in the age of AI. Their rare combination of deep security expertise and software development experience gives them an edge few others have, a ground-level understanding of the problem and a solution that works seamlessly for both security and engineering teams. For any team building at AI speed, this isn’t a nice-to-have, it’s essential. We’re humbled by what the Oplane team have built and convinced this is a massive market opportunity with a product customers genuinely need today,” says Geeta Schmidt, General Partner, Seed Capital.
The capital will be used to scale go-to-market operations across Europe, and expand Oplane’s integrations with AI coding tools including Claude Code, Cursor, and GitHub Copilot. The team also plans to grow the team with senior hires in software engineering, cybersecurity, QA and GTM.
