AI observability and trust platform
fiddler.ai (opens in a new tab)Fiddler was founded to build trust into AI, helping organisations deploy trustworthy and transparent systems. Generative AI and agents unlocked generalised capability while simultaneously widening the risk surface and making it much harder to confirm that an application is working correctly — the failure modes are subtle and the outputs plausible. AI engineers, data science and business teams use Fiddler to monitor those systems, and the company partners with AI-first organisations to build durable frameworks for responsible AI practice, which in turn builds trust with their own users.
