Early Stage Partners

What Early Stage Partners does

Early Stage Partners is a private venture capital firm founded in 2001 and headquartered in Cleveland, Ohio, with a secondary office in Cincinnati. The firm invests in early-stage healthcare and technology companies, primarily across the Midwest, serving founders building innovative products in medical devices, digital health, software, and adjacent technology markets. With an employee base of 11-50, it operates at the scale of a focused regional VC, sourcing and underwriting deals while providing active support to portfolio management teams.

The firm's portfolio includes HistoSonics, OnShift, Blue Spark Technologies, ShiftKey, and Arisdyne. Notable milestones include OnShift's $18M Series D in April 2016, a strategic investment in OnShift by Clearlake Capital in October 2018, a strategic investment in OnShift by ShiftKey in June 2022, a $102M funding round for HistoSonics in August 2024, and the $2.25B acquisition of HistoSonics in August 2025. Portfolio company Blue Spark Technologies has engaged Carnegie Mellon University on machine-learning/AI algorithm development, signaling exposure to AI-enabled healthcare/tech themes.

The firm's business model follows the standard venture capital construct: it raises limited-partner-funded vehicles, earns management fees during the investment period, and realizes carried interest from successful exits. Revenue is concentrated in fund management fees (typically 1.5-2% of committed capital) plus a share of profits from liquidity events such as the 2025 HistoSonics exit. Public AUM and fund-size disclosure is limited, which constrains precision around revenue scale.
