Seattle-based WhyLabs has raised $10 million in a Series A funding round led by Defy Partners and Andrew Ng's AI Fund. The company provides an observability platform for monitoring data health and model health, which is now available for free self-serve usage. The investment will be used to meet growing demand, expand platform capabilities, scale operations, and continue building its world-class team. WhyLabs' AI Observatory enables teams to monitor, understand, and improve their AI applications, making it the first monitoring solution that AI builders can self-onboard and start using for free.
