Using agents to build an agent company: Joao Moura
Takeaway
CrewAI is using its own multi-agent platform to run marketing, sales qualification and docs at scale, and is doubling down on code-executing, trainable crews.
Summary
- Joao Moura (CrewAI CEO) reports 10.5M+ agent executions in the last 30 days and ~100k crews/day running on CrewAI; 16k+ GitHub stars and 8k+ Discord members.
- Origin story: built CrewAI to auto-write his own LinkedIn posts; agents now power CrewAI's marketing (content creator + social analyst + writer + CCO crew yielded 10x views in 60 days), lead qualification (15+ customer calls in 2 weeks) and code documentation.
- Frames the architectural shift: classical software has typed I/O and deterministic behavior; agent apps are fuzzy black boxes that need caching, memory, guardrails and inter-crew communication layers.
- Announces new CrewAI features: 'allow_code_execution' flag giving agents an automated coder/CLI executor, and a 'train your crew' CLI that bakes user feedback into agent memory for consistent results.
- Cites Dharmesh Shah (HubSpot CTO) and Jack Altman among investors and lists production users to argue CrewAI is past prototype stage.

Original description
This talk is about a simple idea: Everyone should be able to use AI to make cool stuff. When I started making crewAI, a framework to build AI Agents, I didn't know just how much it would change the way I work. This isn't just a chat about building AI Agents; it's a story about how these tools helped us grow our business and how they can help you too. I'll share our adventure with crewAI, showing how we used AI to solve problems, save time, and come up with new ideas. It's a journey of discovery and making things better with AI, showing everyone that they can use AI in their work and projects. Recorded live in San Francisco at the AI Engineer World's Fair.
