Nikola Borisov
Nikola Borisov is the co-founder and CEO of Deep Infra, a Palo Alto cloud company that runs open-source AI models as a low-cost, low-latency inference service. A former competitive programmer who scaled messaging backends to hundreds of millions of users at imo.im and helped build HalloApp's founding backend, he bet early that inference, not training, would become the real bottleneck of the AI era. Deep Infra now processes close to five trillion tokens a week and raised a $107M Series B in May 2026 backed by NVIDIA, 500 Global, Felicis and others.
Simon Mo
Simon Mo is the CEO and co-founder of Inferact, the startup commercializing vLLM, the open-source inference engine he helped create and now leads as lead maintainer. A PhD student at UC Berkeley's Sky Computing Lab advised by Ion Stoica and Joseph Gonzalez, Mo has spent roughly eight years building high-throughput, memory-efficient model-serving systems, from Ray Serve at Anyscale to vLLM, which now powers inference for companies including Amazon. In January 2026 he and his vLLM co-maintainers raised a $150M seed round at an $800M valuation, co-led by Andreessen Horowitz and Lightspeed.
Ying Sheng
Ying Sheng is the co-founder and CEO of RadixArk, an AI infrastructure company that spun out of SGLang, the open-source inference engine she helped create in 2023. SGLang now runs across hundreds of thousands of GPUs and serves trillions of tokens a day for Google, Microsoft, NVIDIA, xAI and others. A Stanford computer science PhD and former xAI technical staff who co-led the inference team behind Grok, she launched RadixArk in May 2026 with $100 million in seed funding led by Accel at a $400 million valuation, on a mission to make frontier-level AI infrastructure open and accessible to everyone.
Alex Yeh
Alex Yeh is the Founder and CEO of GMI Cloud, a GPU-native AI cloud infrastructure company he built from Bitcoin mining data centers into a global AI infrastructure leader in just 30 days. GMI Cloud — one of only 6 NVIDIA Reference Platform Partners worldwide — raised $82M in Series A funding in 2024 and is behind a $12 billion sovereign AI infrastructure initiative in Japan. Yeh's mission: make building AI applications as simple as building a website on Shopify.
Mitesh Agrawal
Mitesh Agrawal is the CEO of Positron AI, a Reno-based AI inference hardware startup that has raised $305M and achieved unicorn status in under 34 months. A co-founder and long-time COO of Lambda Labs - where he helped grow revenues from $500K to ~$500M - Agrawal brought his front-row view of GPU limitations to Positron, a company building purpose-built silicon (the Atlas system, and next-gen Asimov chip) that delivers 3x the performance of Nvidia GPUs at one-third the power. Backed by Arm, Qatar Investment Authority, Jump Trading, and others, Positron is building America's first at-scale AI inference silicon company.
