We back medical device companies that seek to transform the standard of care.
An investment platform active across the lifecycle of medical device innovation, from early clinical stage through commercialization. We invest alongside leading venture capital and institutional investors. Active at the board. Selective by design, operator-aligned, clinician-vetted.
Telperion was the elder of Tolkien's Two Trees of Valinor, a silver tree whose light revealed merit, and whose fruit could lie dormant for years before awakening.
We invest the same way: patient capital, clinical scrutiny, boardroom judgment. The naming of our vehicles, like the platform, is deliberate.
Telperion Partners is an investment platform that has been backing medical device companies since 2017.
Our model is intentionally narrow. We invest in private medical device companies across the lifecycle from early clinical stage through commercialization, typically alongside top-tier institutional leads through purpose-built investment vehicles, each aligned to a single company.
We typically commit our own capital alongside investors on each deal.What we offer that conventional funds do not: clinical depth at the diligence stage, active engagement at the board level, observer or director seats at nearly every portfolio company, and the patience to underwrite outcomes measured in years, not quarters.
The platform draws on robust medical and clinical depth, business acumen, financial judgment, and legal rigor in equal measure. Each principal contributes a different lens, and every deal we sponsor reflects all four.

He serves as managing member of Telperion Manager LLC and Athelas Manager LLC, the entities through which the platform's investments are organized and, alongside the other principals, holds board observer rights at nearly every portfolio company.

Aaron has been a principal on every Telperion Partners investment since 2021, including the firm's three Capstan Medical rounds, two Rivermark rounds, and investments in Bright Uro, Mendaera, Verve Medical, HistoSonics, and Spirair, with shared responsibility for sourcing, diligence, investor relationships, and ongoing portfolio oversight.

His legal background, approximately a decade at Bingham McCutchen LLP followed by a role as SVP and General Counsel of a New York real estate development firm, informs his approach to deal structuring across the portfolio.
Matt has been a principal on every Telperion Partners investment, beginning with Auris Health in 2017. He brings clinical depth to diligence that capital alone cannot replicate. Most of the platform's investments are in technologies Matt could plausibly use, train others on, or evaluate from direct surgical experience.
He serves as managing member of Telperion Manager LLC and Athelas Manager LLC, and as a board director of Rivermark Medical. Alongside the other principals, Matt holds board observer rights at nearly every portfolio company.
Matt is a board-certified urologist and a Fellow of the American Board of Urology and the American College of Surgeons, with active surgical privileges across eight hospitals in Florida and California.

He serves as a key opinion leader for Intuitive Surgical, Medtronic, Boston Scientific, Teleflex / Neotract, UroMedica, and others. He is the lead U.S. trainer for the ProACT system.
Dean is an academic urologist whose research and clinical interests sit directly inside the platform's most active thesis areas: voiding dysfunction, BPH, sacral neuromodulation, and men's health. He has been a principal on Telperion Partners investments since the first Rivermark round in 2023 and contributes deep clinical evaluation across the urology portfolio.
He serves as managing member of Athelas Manager LLC and, alongside the other principals, holds board observer rights at nearly every portfolio company.
