Career
Toothy AI
Chen co-founded Toothy AI, a company focused on building artificial intelligence tools designed specifically for dental clinics. The company's core product addresses two persistent pain points in dental practice operations: insurance verification and billing. In dental offices across the United States, administrative staff typically spend significant time manually contacting insurance companies to verify patient coverage details before appointments, and subsequently managing the complex billing and claims submission process after procedures are completed. Toothy AI applies artificial intelligence and automation to streamline these workflows.
Toothy AI was accepted into Y Combinator's Winter 2025 (W25) batch, providing the company with seed funding, mentorship, and access to Y Combinator's extensive alumni network. Y Combinator, based in San Francisco, has previously backed companies such as Airbnb, Stripe, and DoorDash, and acceptance into its program is considered a significant milestone for early-stage startups.
The dental industry in the United States represents a substantial market for administrative technology solutions. Dental practices frequently deal with a wide variety of insurance plans, each with different coverage terms, fee schedules, and pre-authorization requirements. The complexity of navigating these systems has historically created bottlenecks that affect both practice revenue and patient experience. By automating insurance verification, Toothy AI aims to reduce the time staff spend on phone calls and online portal checks, while its billing features seek to minimize claim denials and accelerate reimbursement cycles.
Toothy AI operates within the broader trend of vertical AI companies — startups that build specialized artificial intelligence products for particular industries rather than general-purpose tools. In healthcare specifically, administrative costs have been a longstanding concern, and the application of AI to tasks such as prior authorization, claims processing, and eligibility checking has attracted increasing attention from both entrepreneurs and investors.
