Building Fonda's infrastructure on Azure let us scale globally without worrying about the foundation. When you're running AI workloads across thousands of founder sessions, reliable cloud infrastructure isn't optional -- it's everything. Thanks for keeping the lights on.

The orchestration layer that ties Fonda's AI together. LangChain made it possible to build structured, multi-step workflows that remember context across the entire 14-step founder journey -- not just one session. Hard to build a co-founder with memory without it.

Fonda's co-founder isn't powered by a single model -- it's powered by the best ones. Claude is a core part of what makes Fonda's advice feel like a real thinking partner and not a generic chatbot. The reasoning quality shows up in every validation verdict and every honest 'your idea is weak' call.
