Amber Yang is an Enterprise Partner at Lightspeed Venture Partners backing highly technical founders building next-generation AI software and infrastructure. Before VC, she founded Seer Tracking - an AI startup that used neural networks to predict space debris orbits with 98% accuracy - winning the $50K Intel Foundation Young Scientist Award and landing on Forbes 30 Under 30 in Science at age 18. A Stanford CS/Physics grad with a philosophy detour at Oxford, she brings a rare trifecta of deep technical chops, founder experience, and investor instinct to the table.
ZeroEntropy is the AI infrastructure company fixing the broken retrieval layer of modern AI applications. Founded in 2024 by Ghita Houir Alami (CEO) and Nicholas Pipitone (CTO), the San Francisco–based startup builds rerankers, embedding models, and end-to-end search infrastructure that outperforms Google, OpenAI, Cohere, and Voyage on public benchmarks. Backed by Y Combinator (W25) and a $4.2M seed round led by Initialized Capital, ZeroEntropy's products — zerank-2, zembed-1, zsearch, and ze-onprem — are used by enterprises including Assembled (serving Stripe, Canva, Robinhood, and Notion). The company's proprietary zELO training methodology, derived from chess Elo ratings and the Thurstone statistical model, produces models with calibrated relevance judgments that binary labels cannot replicate.
