Selina Li is Co-Founder and CEO of Bubble Lab, a Y Combinator W26 company that deploys Pearl, an AI-powered ops super-employee directly into Slack. She previously co-founded gymii.ai, a social-first AI nutrition tracking app that combines cutting-edge AI with community features.

Selina graduated from the University of Pennsylvania in 2023 and earned her MEng in Computer Science from Cornell Tech in 2025. She spent 16 years as a competitive golfer, representing Hong Kong in international tournaments and organizing a charity golf fundraiser that raised $100,000 for underprivileged children.

Selina was previously a Quant Researcher at JPMorgan and brings a unique blend of technical expertise and athletic discipline to entrepreneurship. She was named an AJGA Scholastic Junior All-American and competed at the highest levels of amateur golf.

Bubble Lab is part of Y Combinator's Winter 2026 batch and is already trusted by thousands of operators across BizOps and RevOps teams. The platform connects to tools like Notion, Jira, HubSpot, Stripe, and Google Workspace to automate operational workflows.

Bubble Lab enables operations teams to eliminate manual work and scale operations without scaling headcount, while her previous venture gymii.ai addressed the 80% abandonment rate in nutrition tracking through AI-powered meal analysis and social accountability features.
