- Matthew Kerrigan** is an American entrepreneur and co-founder of **Toothy AI**, a health technology company that uses artificial intelligence to automate insurance verification and billing processes for dental clinics. Toothy AI was part of the **Y Combinator Winter 2025** batch and is based in San Francisco, California.[1]
Career
Prior to founding Toothy AI, Kerrigan served as Co-Founder and Chief Technology Officer of **Salezilla**, a venture-funded AI company focused on automating business-to-business sales workflows. At Salezilla, he worked alongside Johnny Chen, who would later become his co-founder at Toothy AI.
Kerrigan co-founded Toothy AI alongside **Johnny Chen**. The company was founded in late 2023 and focuses on the dental revenue cycle management (RCM) space. The company's core product consists of AI agents that handle insurance-related tasks for dental practices, including verifying patient insurance policies, submitting claims, posting payments, and following up on accounts receivable. According to Toothy AI, the average dental clinic spends over 160 hours per month on such insurance tasks.[2]
Toothy AI's platform integrates directly with dental practice management software (PMS), allowing it to automatically verify insurance eligibility for upcoming appointments—up to two weeks in advance—and write the results back into the clinic's existing system. The company also employs voice AI technology to make calls to insurance companies on behalf of dental practices. Toothy AI reports that its clients have achieved collection ratios above 97% and save between 80 and 240 hours per month on insurance-related administrative work.[2]
The company combines its AI automation with human dental revenue cycle experts to handle the full workflow from insurance verification through payment collection. It also provides dashboards and reporting tools that give dental practices real-time visibility into their verifications, billing, collections, and aging claims.
As of early 2025, Toothy AI had approximately seven employees and was classified as an active company within Y Combinator's portfolio, operating in the artificial intelligence, health tech, healthcare, dental, and conversational AI sectors.[1] Kerrigan is based in the Greater Chicago Area.
