Infinity.inc, an early-stage AI infrastructure research company, has closed a $15 million seed round at a $100 million post-money valuation. Touring Capital led the participation, joined by Principal Venture Partners, executives from major chip companies, researchers from OpenAI and Anthropic, and a group of angel investors. The company’s core product is Ignition, an autonomous AI agent that writes, tests, and optimizes the low-level compute kernels that determine how efficiently a chip runs AI models.
