Tennr, a New York-based healthtech startup, has raised US$101 million in a series C funding round, increasing its valuation to US$605 million.

The round was led by venture capital firm IVP, with contributions from Google Ventures and existing investors Andreessen Horowitz and Lightspeed.

The funding will facilitate Tennr’s growth in developing new tools and addressing additional medical specialties. While specific financial details were not disclosed, the company reported tripling its revenue since its series B round in 2024.

Founded in 2021 by Diego Baugh, Trey Holterman, and Tyler Johnson, Tennr aims to address inefficiencies in the US patient referral system.

The company has created a proprietary model that automates processes such as eligibility checks and payer rule verification.

CEO Trey Holterman said that Tennr’s model is designed to manage medical documents and complex tasks like interpreting doctors’ notes. The platform adheres to regulations such as HIPAA through the use of data de-identification.

🧠 Food for thought

1️⃣ The massive referral failure rate represents a critical healthcare system breakdown

The healthcare referral crisis that Tennr aims to solve is far more widespread than most patients realize, creating significant gaps in care delivery.

Research shows that 55-65% of patient referrals are completely lost in the system, leading to missed diagnoses and disrupted treatment plans for millions of Americans each year1.

This breakdown occurs despite referrals being extremely common, with over one-third of Americans referred for specialty care annually. However, the majority never complete the process due to administrative hurdles2.

The problem is compounded by approximately 20 million clinically inappropriate referrals annually, which not only waste resources but further congest an already overwhelmed system3.

These statistics explain why Tennr’s approach resonates with providers and investors alike. The company is addressing a fundamental breakdown point in healthcare delivery that affects tens of millions of patients annually.

2️⃣ Healthcare’s referral network structure creates inherent inefficiencies

The U.S. patient referral system operates as a “small-world” network with specific structural patterns that make centralized solutions particularly valuable.
