Builder After Hours with MongoDB, Mastra, and Tavily

​Close out the week at Builder After Hours: an evening for developers, technical founders, and AI builders to eat, drink, learn, and build.

​We're kicking things off with a technical panel on Context Engineering for Long-horizon AI Agents, featuring engineers from MongoDB, Voyage AI, Tavily, and Mastra. They'll dig into the real challenges of building agents that stay reliable across long, multi-step workflows, from retrieval and memory to production-ready infrastructure.

​After the panel, stick around for co-working, happy hour, and direct access to technical experts who can help you move your next project forward before heading into the weekend.

​Agenda

​🍴 5:00–5:45 PM: Grab a bite, meet other builders, and settle in for the evening

​🎤 5:45–6:30 PM: Hear from experts at MongoDB, Voyage AI, Tavily, and Mastra on what it takes to build modern AI applications

​💻 6:30–8:30 PM: Keep building in a private cafe, get feedback from technical experts, and connect with other developers before you break for the weekend

Tavily is the real‑time search engine for AI agents and RAG workflows; fast and secure APIs for web search and content extraction.

Mastra is the open-source TypeScript framework and enterprise platform for building production-ready AI agents, giving developers the tools to ship reliable agentic applications with built-in memory, evals, and observability.
