Will Bryk is the co-founder and CEO of Exa, a neural search engine built for the AI era. A Harvard CS and physics graduate who interned at SpaceX and engineered AI products at Cresta, Bryk left to answer a question that gnawed at him: what if Google was already obsolete? Exa reimagines search using transformer-based link prediction - what Bryk calls 'neural PageRank on steroids' - to help AI agents find exactly the right information rather than keyword-stuffed SEO noise. The company raised $85M in a Benchmark-led Series B at a $700M valuation in September 2025, with Nvidia and Lightspeed also backing the bet that AI systems will soon generate more search queries than humans.
Aravind Srinivas is the co-founder and CEO of Perplexity AI, the citation-backed AI answer engine that reached a $21B+ valuation in under three years. Born in Chennai in 1994, he earned a dual degree from IIT Madras before completing a PhD at UC Berkeley, then worked as a researcher at OpenAI, DeepMind, and Google Brain before founding Perplexity in 2022. India's youngest billionaire at 31, he has positioned Perplexity as a direct challenger to Google Search by insisting that every AI-generated answer carry verifiable citations - a principle he lifted straight from academic paper standards.
Gabriel Weinberg is the founder and CEO of DuckDuckGo, the privacy-focused search engine he built from his basement in Valley Forge, Pennsylvania starting in 2008 - while simultaneously being a stay-at-home dad. A former MIT physicist who sold his first social network for $10 million just before Facebook made it obsolete, Weinberg turned DuckDuckGo into a billion-dollar company processing over 100 million searches daily, without tracking a single user. He is also the co-author of 'Super Thinking' and 'Traction', two widely-read books on mental models and startup growth.
