Braintrust's series B: building the infrastructure for production AI

Braintrust has secured $80 million in Series B funding, led by ICONIQ, with participation from previous investors such as Andreessen Horowitz and Greylock, to enhance its role as an observability layer for production AI. Founded to address the challenges of AI observability experienced by its creator at companies like Impira and Figma, Braintrust focuses on solving real user needs. As AI becomes embedded in everyday workflows, traditional observability tools struggle to keep up with the complexity and scale of modern AI systems. Braintrust aims to treat AI observability as a core infrastructure component, providing clarity and accountability in rapidly changing AI environments. The company emphasizes a customer-centric approach, engaging directly with users to improve their products. ICONIQ's General Partner Matt Jacobson praises Braintrust's dedication to meeting customer needs, seeing it as a key trait of successful companies. With the new funding, Braintrust plans to expand its engineering and go-to-market teams and develop new products, maintaining its commitment to customer focus as it grows.
