Tullie Murrell
Tullie Murrell is the CEO and co-founder of Shaped, a New York startup building a real-time retrieval engine for search, feeds, and agents. Before Shaped, Murrell spent about five years at Facebook AI Research, where he created PyTorchVideo, the leading open-source library for video understanding, and was an early core contributor to PyTorch Lightning, a training framework now used by millions of developers. The video models he led powered Facebook newsfeed ranking and Instagram Reels. In 2021 he left big-tech research to package that same personalization machinery into a self-serve product for companies without armies of ML engineers. Shaped went through Y Combinator's W22 batch and raised an $8M Series A led by Madrona Ventures in July 2024.
Lubomir Bourdev
Lubomir Bourdev is a computer-vision scientist turned serial founder. He was the first person hired at Facebook for computer vision and a founding member of Facebook AI Research, where he built the object-recognition engine that runs on every photo and video across Facebook and Instagram. He co-founded WaveOne, a deep-learning video-compression company acquired by Apple in 2023, and earlier shipped the face detector inside Adobe Photoshop Elements. Today he is co-founder and CEO of Primepoint, a San Mateo startup building AI that reads and understands construction drawings, which closed a $10M seed round in April 2026. He holds a PhD from UC Berkeley, more than 175 patents, and over 100,000 research citations.
Aaron Wang
Aaron Wang is the co-founder and CEO of Alex (formerly Apriora), a San Francisco AI company whose autonomous recruiter, also named Alex, runs thousands of phone and video interviews a day for Fortune 100s, Big Four accounting firms, and staffing agencies. A Brown triple major who went from a quant trading desk and Facebook AI Research to a Y Combinator startup, Wang bet that a 10-minute conversation reveals more than any LinkedIn profile, then bought the alex.com domain for more than $500K to prove it. The company raised a $17M Series A led by Peak XV Partners in September 2025.
