Emmanuel Paraskakis will help you build what agents want
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 OpenAPI 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 Product Managers and Engineers fast-track their careers.
