Dentronic, a Silicon Valley-based medical AI robotics startup focused on dental care automation, has secured $1 million (approximately KRW 1.49 billion) in pre-seed funding through the Founder Fellowship program of South Park Commons (SPC), a prominent founder community and early-stage investor based in Silicon Valley.

South Park Commons runs its Founder Fellowship to back early-stage founding teams at the idea stage, offering capital alongside partner mentorship. The program has a strong track record, with past investments including Replit, Goodfire, Gamma, and Cognition AI. Dentronic’s first institutional backer, Crew Capital, focuses on campus-based entrepreneurs in both Korea and the United States.

Dentronic is developing robotic systems designed to automate the repetitive physical tasks that assist dentists during clinical procedures. The company was co-founded by Kyoungyeon Choi, who holds degrees in mechanical engineering and dentistry from Seoul National University; Soy Choi, a Harvard graduate currently pursuing a doctoral degree in robotics at Stanford; and Minjun Lee, who studied electrical and computer engineering at Seoul National University. The team is building technology grounded in real clinical challenges.

In 2025, the company developed Dexor, a chairside robotic arm designed to handle repetitive assistance tasks during dental procedures — such as suction and retraction — without requiring the presence of a dental assistant. The six-degrees-of-freedom robot features a passive-mode operating structure and a hardware design that minimizes backlash, allowing for precise and reliable motion. The initial production run of 50 units sold out entirely, and Dentronic is now preparing for mass production.

In the near term, Dentronic aims to scale Dexor rapidly through partnerships with large U.S. Dental Support Organizations (DSOs), targeting a market where the shortage of dental assistants has become an increasingly acute problem. Over the longer term, the company plans to expand its technology across broader medical workflows, including surgical environments, and to progressively introduce physical intelligence capabilities — enabling AI-powered robots to recognize and manipulate instruments in real clinical settings.

“Just as autonomous vehicles have grown more sophisticated by accumulating data in real-world environments, Dentronic will advance step by step by gathering data from actual clinical settings,” said Kyoungyeon Choi, CEO of Dentronic. “Our goal is to use physical AI to reduce the burden on clinicians and ensure more patients have access to consistent, high-quality care.”
