Braintrust

Braintrust envisions a future where building AI products is seamless, iterative, and reliable by embedding intelligent evaluation directly into the development process. We believe the next generation of software will be fundamentally AI-powered, and delivering quality AI experiences demands unprecedented precision and agility.

We are pioneering an integrated AI observability platform that transforms how engineers and product teams measure, improve, and ship AI solutions at scale. By automating evaluation workflows, optimizing prompts in real-time, and offering secure, enterprise-ready tools, Braintrust creates the infrastructure that accelerates innovation and ensures trustworthy AI products.

Driven by a commitment to developers and backed by cutting-edge software engineering practices, we are building the foundation for the future of AI engineering—where evaluation is not an afterthought but a continuous, embedded core of AI product creation.

An Essential Platform for Modern AI Development

We've watched dozens of AI development platforms emerge, but Braintrust stands out as something special. What caught our attention isn't just their impressive client roster (think Notion, Stripe, and Vercel) – it's how they've fundamentally rethought the AI development workflow.

Why Engineers Love It

The platform's genius lies in its focus on continuous evaluation. Instead of the traditional "build-then-test" approach, Braintrust automatically evaluates every change to your AI model or product. It's like having a quality control team working 24/7, catching issues before they become problems.

We're particularly impressed by their native JavaScript/TypeScript support. While most AI platforms cater exclusively to Python data scientists, Braintrust speaks the language of modern web developers. This isn't just convenient – it's transformative for teams building AI-powered applications.

Enterprise-Ready from Day One

Security and compliance often feel like afterthoughts in AI tools, but not here. With SOC 2 Type II certification and flexible deployment options (including self-hosting), Braintrust is built for serious enterprise use. The granular permissions system is especially well-thought-out for large teams.

Room for Growth

While Braintrust excels at what it does, we'd love to see more educational resources for teams just starting their AI journey. The platform is powerful but can feel overwhelming at first – though their free access for open-source projects helps offset this learning curve.

Overall, we see Braintrust as an essential platform for any team serious about building production-grade AI applications. It's not just about building AI anymore – it's about building it right, and Braintrust provides the infrastructure to make that happen.
