dMetrics
dMetrics is an AI company that builds Minsky, a natural-language-processing platform letting non-technical subject-matter experts create their own AI models to read, track, and analyze huge volumes of messy text - without writing code. Founded by two MIT machine-learning PhDs, the company started by decoding healthcare conversations across social media and now serves financial, pharmaceutical, and public-sector customers, including a five-year, $99.5M U.S. Department of Defense production contract for open-source threat analysis.
ZeroEntropy
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.
