Our take
AI and machine learning are increasingly shaping the way organizations make decisions. However, one major challenge is that AI technology often operates as a "black box". Unlike traditional software, where developers can review code to understand its logic, AI systems can be opaque, making it difficult for companies to fully grasp how data is interpreted and outcomes are reached.
Fiddler AI aims to address this gap with an explainable AI platform that offers transparency into how models make predictions. By providing clear insights into decision-making processes and enabling adjustments when bias is detected, Fiddler enhances trust and accountability in AI systems.
This focus on building trust in AI comes at a crucial time, as the market is expected to grow over 30% annually. Fiddler AI has already partnered with major banking institutions and online brands like Etsy. And with an impressive $30 million Series C funding round behind it, Fiddler is well-positioned to compete with rivals like Reflektion and Conviva.
