Audio By Carbonatix

NEW YORK--(BUSINESS WIRE)--Dec 1, 2025--

Jane Street, a global technology-driven trading and investment firm, today announced it led a seed investment round in Numerata with participation from CoreWeave Ventures. Numerata is a developer of AI-powered software development tools built to boost developer productivity and reduce expensive errors using custom model training techniques and a low-latency autocomplete backend.

"We are building computation as an extension of thought,” said Kevin Wang, Founder of Numerata. “Our approach recognizes that human developers will remain core to software development, and new productivity gains come from tools that augment human expertise rather than replace it. Having Jane Street as both our investor and a flagship customer and CoreWeave as a cloud partner and our investor validates our vision of making customized AI models as accessible as open-source software.”

"Jane Street's partnership with Numerata underlies our expanding commitment to back transformative technology companies as both a strategic partner and investor throughout their whole lifecycle, from seed stage to public markets,” said Jane Street. "Our approach combines a technical-first diligence with patient, flexible capital, backed by deep infrastructure expertise from building and operating global technology systems.”

“CoreWeave Ventures backs founders who are redefining what's possible in AI by connecting innovative capital with access to the CoreWeave AI Cloud,” said CoreWeave's Cofounder and Chief Development Officer Brannin McBee. “Numerata manifests the ambitious, technical vision we look for. They're already turning powerful ideas into real breakthroughs.”

Numerata's product, NinetyFive, addresses a critical priority in software development: enabling developers to access and leverage AI-driven innovations while ensuring privacy and maintaining full control over proprietary codebases. Compared to many cloud-based services, Numerata's AI/ML deployments offer secure custom model training capabilities, allowing enterprises to train models on their private codebases, and then deploy their trained, custom models for their developers to use. These models produce a tool customized to the software of the enterprise instead of what's publicly available.
