DeepJudge develops search software for law firms' internal documents.

ETH Zurich, EPFL and the Swiss National Supercomputing Centre released Apertus in 8-billion- and 70-billion-parameter versions on September 2, 2025. The release makes model weights and documentation of the architecture, training data and methods openly available under a permissive licence allowing research and commercial use.

The models were trained on 15 trillion tokens covering more than 1,000 languages, with 40% of the training material in languages other than English. These include Swiss German and Romansh. Developers can download the models through Hugging Face or access them through services including Swisscom's Swiss AI Platform.

Zurich-based DeepJudge raised USD 10.7 million in an oversubscribed seed round led by Coatue. Participating investors included Gokul Rajaram and Michele Catasta, alongside existing backers. Its search tools helped law firms and legal departments retrieve information from internal documents, including records in document-management systems and Microsoft 365.

Alongside the financing, DeepJudge announced availability of Knowledge Assistant, a generative-AI interface connected to its enterprise search. It used retrieval-augmented generation to ground responses in an organisation's own records. The company named Homburger and Lenz & Staehelin among users discussing its search technology.
