Ryan Ning is Co-Founder and CEO of Simulithic (YC F26), an AI-powered user simulation platform built for production monitoring and quality assurance.

Ryan studied at the University of Toronto, where he conducted undergraduate AI research, before completing software engineering internships at Uber and Shopify.

Ryan turned down a prestigious Amazon DynamoDB internship to join Y Combinator Fall 2026, betting on his vision of simulating real user behavior at scale.

At Simulithic, Ryan co-leads a two-person team building AI agents that replicate authentic user journeys across devices, browsers, and account states to surface failures that traditional testing misses.

Backed by Y Combinator with $500K in funding, Simulithic is redefining how engineering and product teams validate changes before real users are ever affected.
