## Summary

YC S21 membership-based dental practice applying One Medical model to dentistry; $125K seed to $1M revenue in SF competing with Tend and Aspen for health-conscious patients avoiding traditional dental insurance.

## Company Overview

Rinse is a San Francisco-based dental care company operating modern, membership-based dental practices with a technology-enabled patient experience — applying the One Medical model (direct primary care with annual membership) to dentistry, providing preventive dental care with simplified scheduling, transparent pricing, and a comfortable office environment for health-conscious consumers who have avoided traditional dental practices. Founded in 2021 and backed by Y Combinator (S21), Goodwater Capital, and Liquid 2 Ventures with $125,000 in pre-seed funding, Rinse reached $1 million in revenue by December 2024.

Rinse's membership model provides annual coverage for cleanings, exams, and X-rays at a flat monthly or annual fee — eliminating the insurance complexity that makes dental care confusing and often prevents preventive visits. The technology layer (online scheduling, digital intake forms, automated appointment reminders) creates the smooth, modern booking experience that health-conscious younger patients expect. The practice design (bright, minimal spaces with music and entertainment during procedures) reduces the anxiety that keeps many patients from visiting dentists annually.

In 2025, Rinse competes in the modern dental practice and direct-to-patient dental care market with Tend (NYC-based modern dental experience, $125M+ raised), Chapter Aesthetic Studio (dental and aesthetics), and Aspen Dental (large DSO) for health-conscious dental consumer market share. The direct primary care/membership dentistry model has proven viable in medicine (One Medical, Iora Health) and is being tested in dental with Tend and Rinse. The market opportunity is the 100M+ Americans who are uninsured or underinsured for dental and avoid routine care due to cost unpredictability. Goodwater Capital's investment provides consumer tech and health tech expertise. The 2025 strategy focuses on opening additional San Francisco area locations, building the subscription membership infrastructure, and growing through word-of-mouth in the health-tech-savvy Bay Area demographic.
