# Serif Health **Source:** https://geo.sig.ai/brands/serif-health **Vertical:** Healthcare **Subcategory:** General **Tier:** Emerging **Website:** serifhealth.com **Last Updated:** 2026-04-14 ## Summary Healthcare price transparency API and data infrastructure for CMS compliance; $1.2M monthly revenue at 8 people from YC W21 normalizing hospital and insurer rate files for health plans and employers. ## Company Overview Serif Health is a Los Angeles-based healthcare price transparency infrastructure company providing APIs and data products that power hospital rate search, insurance network intelligence, and CMS compliance analytics — helping health plans, self-funded employers, TPAs (third-party administrators), and data analytics firms navigate the complex requirements of the CMS Price Transparency and Transparency in Coverage rules that mandate hospitals and insurers to publish machine-readable pricing files. Founded in 2020 and a Y Combinator W21 graduate, Serif raised $2.52 million from 1984 Ventures and angel investors, achieving $1.2 million in monthly revenue as of December 2024 with an 8-person team. Serif's infrastructure processes the enormous machine-readable files that hospitals and insurers are required to publish under CMS rules — files that often exceed 10GB+ per hospital and are published in inconsistent formats across thousands of healthcare entities. Serif normalizes, indexes, and makes this data queryable through APIs, enabling health plans to monitor network adequacy, employers to understand what they're paying for employee healthcare versus market rates, and analytics companies to build cost-comparison tools on top of standardized data. In 2025, Serif Health competes in the healthcare price transparency and data infrastructure market with Turquoise Health (hospital rate transparency), Ribbon Health (provider data and network intelligence), and Change Healthcare (Optum, healthcare data infrastructure) for healthcare price and network data intelligence. The CMS Price Transparency rules (effective 2021 for hospitals, 2022 for insurers) have created a new market for data infrastructure companies that can make sense of the massive, non-standardized data dumps that healthcare entities are required to publish. The $1.2 million in monthly revenue at 8 people is exceptionally capital-efficient. The 2025 strategy focuses on growing the health plan and employer compliance customer base, deepening the analytics that help buyers understand price variation, and building the network adequacy monitoring that helps health plans ensure their networks meet CMS requirements. ## Frequently Asked Questions ### What is Serif Health?
