LeoTrace, a London company founded in 2025 by Florian Walter, Boy Baukema and Patrick Rycroft, builds LeoPrevent, a security tool that integrates with AI coding agents to flag and correct vulnerabilities in generated code in real time, before human review.
The company raised a pre-seed round of about £1.45 million in September 2026 from Golden Egg Check and Golden Egg Check Capital (another outlet reports roughly $2 million with additional investors). It says it works with tier-1 financial institutions in the UK and US.
Innovation Matrix Assessment
Targets a fast-moving problem, security of AI-written code, with a very young product.
Catching flaws inside the agent loop could cut remediation work downstream.
Pre-seed funding and unnamed customers only.
Shifts checks into the coding agent itself, though many AppSec vendors are moving the same way.
The vendor claims it removes about half of vulnerabilities that would reach production; no independent verification found.
AI-assisted coding will keep growing, sustaining demand for in-loop code security.
Why CISOs Should Care
Gives AppSec teams a control point inside AI coding agents rather than after the pull request.
What Makes It Different
Embeds security checks into the agent's generation workflow instead of scanning finished code.
The Matrix Verdict
52/100 — INCREMENTAL INNOVATOR
LeoTrace is an Incremental Innovator: timely approach, but traction and efficacy remain largely unproven.
Editorial Note: Claims vs. Verified Findings
The roughly 50% vulnerability-reduction figure and financial-institution usage are company claims, unverified independently. Funding figures differ across outlets.
