An ultrafast open-source inference startup has closed a $100M Series A co-led by Blackbird VC and Abstract, with participation from QED Investors, 645 Ventures, Carbide Ventures and others; existing backers doubled down. The team argues demand for ultrafast inference will be many times larger than slow inference but has never reached the market at scale, and plans to bring its first racks live in Q1 2027.
