Oplane
A Malmö, Sweden startup that automates security threat modeling for engineering teams building software with AI coding assistants like Cursor and Copilot.

Oplane builds an automated security architecture platform aimed specifically at teams using AI coding assistants (Claude Code, Cursor, GitHub Copilot). It maps a codebase’s architecture, applies expert-style threat modeling to identify system-level security requirements as code is generated, and pushes contextual remediation guidance directly into developers’ existing workflows rather than producing a separate report reviewed after the fact.
The company’s bet is that AI-generated code changes the threat-modeling problem: architecture and data flows can shift far faster than a human security architect can manually review, so the process needs to run continuously and automatically alongside AI-assisted development rather than as a periodic manual exercise.
Founded in Malmö in 2022 by Emil Kvarnhammar, Oscar Andersson, and Anders Söderling, Oplane raised a €4.5M seed round in June 2026 led by Copenhagen-based Seed Capital, with participation from existing investor Icebreaker.vc and several named angel investors, funding earmarked for European commercial expansion and deeper AI-coding-tool integrations.
Innovation Matrix Assessment
Built a working automated threat-modeling product with direct integrations into current AI coding tools and secured a fresh seed round in 2026 timed to the AI-coding adoption wave.
Automating threat modeling addresses a step security teams historically struggle to scale, particularly as AI-generated code accelerates development velocity.
A €4.5M seed from a credible Nordic investor group is real but early-stage validation; no disclosed customer count or enterprise logos were found.
Continuous, AI-coding-aware threat modeling addresses a genuinely emerging gap that most existing AppSec tooling was not designed for, though the category is still nascent and contested.
No independent benchmarks or named customer results were found; effectiveness of its automated threat-modeling output versus manual review is not independently verified.
As AI-assisted coding becomes standard practice, continuous architecture-aware threat modeling is likely to remain relevant rather than a passing niche.
Why CISOs Should Care
Helps AppSec teams keep pace with AI-accelerated development by surfacing architecture-level security requirements automatically instead of relying on manual threat-modeling sessions that can't scale to AI-generated code volume.
What Makes It Different
Threat models continuously as code is generated and integrates directly into AI coding assistants' workflows, rather than functioning as a separate, periodic review tool.
The Matrix Verdict
52/100 — INCREMENTAL INNOVATOR
An Emerging-to-Incremental Innovator: a well-timed, well-funded response to a real and growing AppSec gap created by AI-assisted coding, but still too early for independent efficacy evidence.
Editorial Note: Claims vs. Verified Findings
The founding team, funding amount, and investors are independently reported by multiple European tech outlets; specific claims about threat-modeling accuracy and remediation quality are vendor-sourced.
