About Zavo

Zavo is a data company building proprietary, real-world data infrastructure for frontier AI. We partner with hospitals, businesses, operators and expert networks globally to access hard-to-reach data that cannot be found on the public internet. We source, structure, annotate and license this data for model training, post-training and evaluation, and use it to build specialised benchmarks and reinforcement learning environments grounded in real-world workflows, expert decisions and outcomes. Our focus spans healthcare and robotics, where high-quality proprietary data, realistic environments and reliable evaluations are critical to building increasingly capable AI systems.
