I'm Emmanuel, 3x VP Product, now a founder at Level 250.

If you built or used APIs in the past 15 years, chances are you've used one of my products. I've led some of the most influential API tools: Apiary (550,000+ APIs), Swagger (750,000+ APIs) and Oracle's first Cloud-Native API Gateway. Before that, I built large B2B API programs at Verisk, Moody's, and Precisely.

Today, I advise Fortune 500 CEOs and AI-forward startup founders on API Strategy, Developer Experience, MCP products, and AI agent readiness.

I'm also a member of the OpenAPI Initiative and a featured speaker at apidays and other global technology conferences.

My passion is helping others build products, which is why I also teach on Maven: to share my lessons learned and help organizations build what agents want.
