Senseonics Holdings
Senseonics Holdings commercializes the only FDA-approved 180-day implantable CGM, led by CEO Tim Goodnow from its Germantown, Maryland base.
Senseonics Holdings
Goodnow, who previously led R&D at TheraSense before its acquisition by Abbott, founded Senseonics in 1996 to pursue a fundamentally different sensor architecture. Where Abbott and Dexcom built their franchises on short-duration needle sensors replaced every 10 to 14 days, Senseonics engineered a fluorescence-based sensor inserted subcutaneously in a five-minute in-office procedure and left in place for up to 180 days. In 2022 the firm received FDA approval for that six-month version of its Eversense E3 system, making it the longest-duration continuous glucose monitor available in the United States. The firm's sole operational focus is the Eversense platform, a Class III medical device that transmits glucose readings every five minutes to a mobile app without requiring daily fingerstick calibrations. Senseonics runs its own direct sales force in the United States targeting endocrinologists and diabetes specialists, while Ascensia Diabetes Care — the former Bayer diabetes unit now owned by Panasonic Healthcare — handles distribution outside the US under an exclusive agreement signed in 2020. The company has publicly reported covering more than 6,000 unique US prescribers by late 2024. Manufacturing takes place at a single facility in Germantown, Maryland, which the firm expanded in 2023 to support increasing sensor demand. As a publicly traded company listed on the NYSE American under the ticker SENS, Senseonics does not publish an AUM figure — it is a commercial-stage operating business, not an investment vehicle. Revenue in 2024 totaled approximately $22.4 million, up from $16.3 million the prior year. The firm carried roughly $43 million in cash and equivalents at year-end 2024 following a direct offering that raised $21 million in January 2025. Leadership remains stable: Goodnow has served as CEO since February 2016, and Dr. Francine Kaufman, a prominent pediatric endocrinologist formerly of Children's Hospital Los Angeles, joined as Chief Medical Officer in 2019. The structural distinction is medical, not financial: Senseonics competes in an insulin-dependent diabetes market historically dominated by Abbott's FreeStyle Libre and Dexcom's G6/G7, both of which require frequent sensor changes. The 180-day implant creates a differentiated cadence — patients interact with the device twice per year rather than twice per month, shifting the clinical conversation toward long-term adherence and in-office insertion economics. That positioning is not a portfolio-allocation choice; it reflects a single-product public company concentrating its entire balance sheet on proving that an implantable sensor can carve durable share from two entrenched incumbents.

Frequently asked questions
How does Senseonics' Eversense sensor differ structurally from Abbott's FreeStyle Libre and Dexcom's G7?
Eversense is a fluorescence-based sensor implanted subcutaneously by a physician in a five-minute procedure, then removed and replaced every 180 days. Abbott and Dexcom sensors sit partially in the skin using a needle-based architecture and are self-applied every 10 to 15 days. The implant approach trades insertion convenience for duration — the patient interacts with the sensor hardware twice per year rather than twice per month, and the transmitter worn over the implant is a removable, rechargeable component rather than a disposable unit attached to each new sensor.
Who runs investment decisions at Senseonics?
Senseonics is a publicly traded operating company on the NYSE American, not an investment firm or family office. Capital allocation decisions — including equity offerings, manufacturing expansion, and R&D spend — are made by CEO Tim Goodnow and the board of directors, and disclosed through SEC filings. There is no investment committee in the allocator sense; the firm's cash is deployed against the commercialization of its single Eversense product line and debt service on its convertible notes.
Does the Ascensia partnership cover US distribution or only international markets?
Ascensia Diabetes Care holds exclusive global distribution rights for Eversense outside the United States under the 2020 agreement, covering key European markets including Germany, Italy, and Spain as well as selected Middle Eastern geographies. Senseonics retains its own direct sales force for the US market and receives a royalty on Ascensia's ex-US sales tied to sensor insertion volumes.
What is Senseonics' cash position and how does it fund ongoing operations?
As of year-end 2024, Senseonics reported roughly $43 million in cash and equivalents, augmented by a $21 million direct offering closed in January 2025 (per the firm, January 2025). The company has historically funded operations through a combination of equity offerings, convertible debt — including a 2023 exchange transaction that reduced outstanding 2025 notes — and product revenue. The firm does not publish an AUM and is not a pooled investment vehicle.
Is Senseonics addressing the non-insulin-dependent Type 2 diabetes population, or is the device focused on insulin users?
The Eversense E3 system is FDA-cleared for adults with all types of diabetes. In practice, physician adoption has concentrated among insulin-requiring patients — both Type 1 and intensive insulin-using Type 2 — where continuous glucose data drives immediate therapeutic decisions. The firm has publicly stated it intends to broaden reach into basal-insulin and non-insulin Type 2 populations as insertion volumes grow, but near-term prescriber penetration is weighted toward insulin-dependent cohorts.
What is the known relationship between Senseonics and the former TheraSense team?
CEO Tim Goodnow was vice president of research and development at TheraSense, a glucose-sensing company acquired by Abbott in 2004 for $1.2 billion. Goodnow founded Senseonics in 1996 before TheraSense was sold. The technical lineage matters: TheraSense commercialized a wired-enzyme sensor technology that became foundational to Abbott's FreeStyle line, while Senseonics chose fluorescence chemistry — a parallel technical bet by the same executive generation on the same disease state, with an opposing architecture.
