NeoSigma

NeoSigma is a product-driven research lab building the intelligence layer that helps close the feedback loop between your customers, products, and AI systems. The company is developing infrastructure that enables AI agents to learn from experience in production, compounding into proprietary intelligence across users, teams, and organizations.

The bottleneck in building AI systems is no longer writing code - it is everything that comes after: building reliable intelligent systems that can sustain and improve themselves over time. NeoSigma is addressing this challenge by creating the infrastructure layer for agents to learn from experience, helping teams capture failures, convert them into structured evaluation signals, and use them to drive continuous improvements in agent reliability.

Backed by world-class investors and leaders from Google DeepMind, OpenAI, World Labs, Mercor, and Decagon, NeoSigma is a small but intensely technical team of researchers and engineers who have trained frontier-scale models and built widely used AI products and agents at MIT, Parallel Web, Essential AI, Apple, and Amazon. The company is headquartered in San Francisco, CA, and is SOC 2 Type 2 and HIPAA compliant.
