Holmes Raises €1.1M for AI-Powered Software Testing

Belgian startup Holmes has successfully closed a €1.1 million pre-Seed funding round, signaling a significant advancement in automated software quality assurance, particularly for applications developed at the accelerated pace of AI. The investment, aimed at refining the detection of software defects before they impact end-users, was spearheaded by Syndicate One. The round also saw robust participation from a notable group of investors, including Aikido founders Roeland Delrue and Willem Delbare, Showpad co-founder Louis Jonckheere, and seasoned entrepreneur Thomas Van Overbeke. Additional backing came from NewSchool, RDY, and 100IN, underscoring broad confidence in Holmes's innovative approach.

Founded by a trio of Belgian tech veterans—Robin Praet, Robbrecht Delrue, and Sofie Buyse—each with a track record of successful ventures, Holmes is positioned to address a critical pain point in modern software development. Praet and Robbrecht Delrue previously co-founded Smartendr, an ordering system for hospitality that was acquired by OrderBilly. Sofie Buyse was instrumental as Henchman's first hire, an AI tool for legal professionals that was later acquired by LexisNexis for a substantial sum. This collective experience fuels Holmes's mission to streamline the quality assurance (QA) process.

The core of Holmes's offering is an autonomous QA platform designed to learn user interaction patterns within software. By continuously testing these real-world usage flows, the platform aims to identify and rectify issues that traditional code-centric testing might miss. This is particularly relevant as AI tools accelerate code generation, often creating a disconnect between syntactically correct code and functional user experience. Holmes bridges this gap by focusing on product integrity from the user's perspective, ensuring that functionality aligns with expectations, even as development cycles shorten.

“The speed of code creation, often augmented by AI, has outpaced the validation of actual user experience,” explained Robin Praet, co-founder of Holmes. “Our platform directly addresses this disparity, ensuring that products not only function correctly from a coding standpoint but also perform reliably in real-world usage scenarios.” The company emphasizes that its solution is built for development teams operating at AI-driven speeds, proactively catching problems before they reach the customer base.

The software testing market, a segment within the broader IT services industry valued in the tens of billions globally, is increasingly strained by the demand for faster release cycles. Traditional QA methods, often involving manual testing or brittle automated scripts, struggle to keep pace. Holmes's autonomous approach, leveraging specialized AI agents to cover various testing dimensions—including happy paths, edge cases, responsiveness, accessibility, and error recovery—offers a compelling alternative. This allows development teams to avoid the trade-off between leveraging AI for speed and maintaining product quality.

“Every software company eventually encounters a growth bottleneck caused by manual testing,” noted Robbrecht Delrue, another co-founder. “We built Holmes to be the solution for that critical juncture, enabling companies to scale their development without being hindered by QA limitations.” The platform integrates seamlessly into existing development workflows, automating the continuous verification of user-facing journeys, from sign-up and navigation to complex transaction processes.

The strategic infusion of capital will enable Holmes to further develop its AI-powered QA capabilities and expand its market reach. The company is actively collaborating with 30 design partners to refine its product and plans a broader rollout in the coming months. Holmes is also benefiting from the guidance of a distinguished advisory board, including tech leaders such as Dieter Wachters (Senior Director of Engineering, Collibra), Haroen Vermylen (co-founder and CTO, Luzmo), Jaap Vergote (co-founder, Upsellplus), and Ivo Minjauw (CPO, Lighthouse), further solidifying its position as an innovator in the quality assurance space.
