Refortifai is building reasoning systems for electronic design automation, the software stack that the semiconductor industry uses to design and verify modern chips. The team is constructing reinforcement learning environments that can solve and evaluate complex EDA tasks such as placement, routing, timing closure, and verification, then training agents inside those environments to produce designs that match or beat human engineers.
EDA has long been dominated by Synopsys, Cadence, and Siemens with rule-based heuristics and slow iterative loops. Refortifai is part of a new wave applying frontier AI to the problem, in the spirit of AlphaChip but oriented toward broader chip-design tasks and tighter integration with industrial workflows. By treating each design challenge as an RL environment with measurable rewards, the company aims to compress design cycles that today take months into hours and unlock chip architectures that current tools simply cannot search.
Founded in 2026 by Sayan Mitra (CEO), Rithik Jain (COO), and Atman Kar (CTO, formerly of Texas Instruments), Refortifai is backed by Y Combinator in the Spring 2026 P26 batch and headquartered in San Francisco. The customer profile skews toward fabless semiconductor companies, hyperscaler silicon teams, and defense electronics groups that own their own RTL and want a reasoning layer on top of existing EDA flows rather than a full tool replacement.
