Abhay Agarwal
Abhay Agarwal is the founder and CEO of Poly, the intelligent cloud file browser built to replace Finder and File Explorer for the AI era. A former Microsoft Research AI fellow and Stanford d.school lecturer, he came up through engineering at UC Berkeley and design at Stanford, then founded the human-centered AI consultancy Polytopal before pivoting it into a Y Combinator-backed startup. In November 2025, Poly emerged from stealth with $8M in seed funding led by Felicis, powered by its own Polyembed-v1 embedding model. Agarwal describes the product as 'an LLM with infinite context from your life,' and frames his life's work around a theory he calls Post-Cognitive Design.
Eric Zelikman
Eric Zelikman is the co-founder and CEO of humans&, a human-centric frontier AI lab in Redwood City building foundation models designed for communication and collaboration rather than automation. A former early researcher at xAI, he helped shape Grok's pretraining data and scaled reinforcement learning for reasoning across Grok 3 and Grok 4. Before that, as a Stanford PhD candidate, he authored STaR and Quiet-STaR, foundational papers that taught language models to reason in natural language using their own rationales. In January 2026, humans& emerged from stealth with a $480M seed round at a roughly $4.48B valuation, backed by Nvidia, Jeff Bezos, GV, SV Angel and Emerson Collective.
Jad Tarifi
Jad Tarifi is the co-founder, CEO and Chief AI Scientist of Integral AI, a Tokyo- and Silicon Valley-based startup building energy-efficient, interactive world models aimed at scalable artificial general intelligence and embodied robotics. Before founding the company in 2021, he spent nearly a decade at Google, where he founded and led the company's first generative AI team and worked on neocortex-inspired learning from limited data. Born and raised in Lebanon, he holds a PhD in computer science and AI from the University of Florida and an MS in quantum computing. In December 2025 he drew global attention - and skepticism - by claiming Integral AI had built the world's first AGI-capable model, TOWA. He is also the author of the four-volume 'Freedom Series' on AI and human potential.
Aran Khanna
Aran Khanna is the co-founder and CEO of Archera, a Bellevue-based startup that helps companies cut cloud bills by guaranteeing deep discounts without locking them into long-term commitments, backed by insurance and reinsurance capacity. A Harvard computer science and math graduate, he first made headlines in 2015 when his Chrome extension Marauder's Map exposed a location-tracking flaw in Facebook Messenger and cost him a Facebook internship. He went on to research privacy at Harvard, build neural-network tools as an AI engineer at AWS, and co-found Archera in 2019 with his brother Nikhil.
Deepak Pathak
Deepak Pathak is the co-founder and CEO of Skild AI, the Pittsburgh robotics company building a single general-purpose 'brain' that can run any robot from a quadruped to a humanoid. A Raj Reddy Associate Professor at Carnegie Mellon, he earned a gold medal at IIT Kanpur and a PhD at UC Berkeley before betting that physical intelligence, not language, is the real path to AGI. In January 2026 Skild raised $1.4 billion at a valuation north of $14 billion, backed by SoftBank, Nvidia, and Jeff Bezos.
Eduardo Reis
Dr. Eduardo Pontes Reis, MD is Vice President of Strategy in the Office of the CEO at Hippocratic AI, a Palo Alto-based generative AI healthcare company with $439M in total funding. A neuroradiologist and AI researcher, he bridges clinical medicine and artificial intelligence through leadership roles at Stanford's Center for Artificial Intelligence in Medicine and Imaging (AIMI) and Hospital Israelita Albert Einstein in Brazil, where he initiated the Health Story medical timeline platform and led AI development for diseases including tuberculosis, COVID-19, melanoma, and head CT analysis. He co-authored the BRAX Brazilian Chest X-ray Dataset published in Nature Scientific Data, built open-source tools for integrating AI plugins into LLMs (plugnplai, 228+ GitHub stars), and served as Founding Radiologist at Cognita Imaging — a Stanford AIMI spinoff acquired by Radiology Partners for $80M — before joining Hippocratic AI in early 2026.
