Crowdsourcing Startups funded by Y Combinator (YC) 2026

The best AI models aren’t just trained and evaluated with human data; they’re built with superhuman data. The strongest datasets emerge through collective intelligence, where humans and machines work together to outperform either one alone. At Centaur, we create superior quality data by turning annotation into an arena where experts and AI compete.

We provides tools, data and systems to facilitate real-time insights, decluttering outbreak detection and enhancing risk mitigation. Our surveillance is used by industry, public heath and consumers globally.
