  • Velaura AI

    Participated · Series A · Aug 2026

    Velaura AI develops energy-efficient digital design technology for AI compute, built on patented techniques applied at leading semiconductor process nodes. Its flagship product, Titan Core, is a proprietary chip IP and design platform that the company says delivers a 2x to 4x improvement in performance per watt on the mathematical operations used by AI accelerators without sacrificing performance. The underlying technology has been deployed across more than 30 million ASICs, and Velaura licenses it under an upfront fee plus a royalty tied to the power savings its customers achieve. The company says it is engaged with hyperscalers and chip partners at 3nm and 2nm nodes to integrate the technology into next-generation AI accelerators, and is extending the architecture into physical AI systems including robots, drones, and autonomous machines. Founded in 2022 as Auradine, a bitcoin mining ASIC designer behind the Teraflux miner series, the company rebranded to Velaura AI in March 2026 alongside a pivot to AI silicon, and is headquartered at 3200 Coronado Drive in Santa Clara, California. Financially, Velaura AI announced a $110M Series A in August 2026 at a valuation above $1 billion, led by Seligman Ventures; the articles do not state a cumulative total raised across its earlier rounds under the Auradine name.
