The Synthesis Company

We enable research that was previously impossible—systematic reviews of 20,000+ papers in weeks with 98% accuracy. We collaborate with researchers at Stanford, Harvard, and Johns Hopkins to ask the big questions they've been forced to scale down. Pharma companies get complete evidence awareness in weeks — not years. AI labs get the same reviews as RL environments with expert-validated reasoning traces—scientific synthesis as the next frontier after math and coding benchmarks. We're former DSPy c

hud

match 69

HUD (YC W25) is developing agentic evals and RL environments for Computer Use Agents (CUAs) that browse the web for frontier AI labs. Our CUA Evals framework is the first comprehensive evaluation tool for CUAs. People don't actually know if AI agents are working reliably. To make AI agents work in the real world, we need detailed evals for a huge range of tasks. We're backed by Y Combinator, and work closely with frontier AI labs to provide agent evaluation and training infrastructure at scale.

Sciloop

match 60

Sciloop creates expert-level math and physics problems that frontier AI models can't solve, then sells the data to AI labs for training and evaluation. Our problems are created by IPhO and IMO medalists — the top 0.01% of STEM talent globally. On our benchmark, models like GPT 5.4 Pro and Gemini 3.1 Pro score 0-5% on our hardest problems. We work with AI labs to supply continuous, fresh training data that pushes the frontier of mathematical and scientific reasoning. Founded by Bilal and Osman, I
