Omnilex Raises $4.5M Seed Round to Transform Legal Research with AI

Swiss legal-tech startup Omnilex has raised $4.5 million in seed funding as it looks to modernize legal research and analysis through artificial intelligence. Founded in 2024 and headquartered in Zurich, the company secured the financing in a round led by Founderful VC, with participation from Plug and Play Tech Center, Tiny Supercomputer Investment Company, Angel Invest, and Swiss angel investor Pascal Mathis.

The seed round marks a significant milestone for Omnilex as demand accelerates for AI-powered tools capable of supporting legal professionals with complex research tasks. The company is building an AI-driven legal research and reasoning platform that aggregates laws, court decisions, and legal commentary into a single workspace. By combining generative AI with structured legal data, Omnilex aims to automate time-intensive research processes and deliver contextualized legal insights for lawyers and in-house legal teams.

According to the company, the newly raised capital will be used to further develop its technology, expand its legal knowledge base, grow its team, and support international expansion. Omnilex has already gained traction among law firms, corporate legal departments, and public sector organizations, reporting that more than 120 organizations are using its platform. The startup has also indicated strong commercial momentum, noting rapid growth in annual recurring revenue over a short period.

Founderful VC, the lead investor, is a Swiss venture capital firm focused on early-stage technology companies, particularly in AI, SaaS, and deep tech. The firm has become an increasingly active player in Switzerland’s startup ecosystem, backing founders aiming to scale globally from the country’s strong academic and technical base. The participation of Pascal Mathis, a partner at Founderful and an experienced angel investor, further underscores confidence in Omnilex’s technical approach and market potential.

Global innovation platform Plug and Play Tech Center brings strategic value beyond capital, offering access to an extensive international network of corporate partners, accelerators, and investors. Its involvement positions Omnilex to explore partnerships with large enterprises and legal departments seeking to adopt AI-enabled legal workflows. Tiny Supercomputer Investment Company, which focuses on early-stage technology investments, and Angel Invest, known for supporting emerging startups at the seed stage, also joined the round, adding to the diversity of Omnilex’s investor base.

Omnilex was founded by Marco Henri and a multidisciplinary team with backgrounds spanning law, computer science, and research. The company’s platform leverages publicly available legal data, enriched with proprietary AI annotation and reasoning layers. By reducing reliance on traditional, high-cost legal databases, Omnilex aims to significantly lower research costs while improving speed and accuracy for legal professionals.

The legal-tech sector has seen growing investor interest as law firms and corporate legal teams increasingly turn to AI to manage rising workloads, regulatory complexity, and cost pressures. Within this environment, Omnilex positions itself as a provider of a reliable AI workspace designed to augment legal expertise rather than replace it, focusing on transparency and traceability in legal reasoning.

With fresh funding secured, Omnilex plans to accelerate product development and expand its footprint beyond Switzerland. As competition intensifies in the global legal-AI market, the company’s early traction, combined with backing from experienced investors, places it in a strong position to pursue further growth and establish itself as a key player in AI-powered legal research.
