Durable Capital Partners

Overview

Durable Capital Partners is a US growth-equity and public-markets investment firm, publicly reported as based in the Chevy Chase/Bethesda, Maryland area, founded by Henry Ellenbogen, who serves as its Managing Partner and Chief Investment Officer. The firm invests across both private late-stage growth rounds and public equities, a "crossover" strategy common among the largest US growth funds, and files 13F disclosures of its public-market holdings with the SEC. Within the DACH region, Durable Capital Partners is documented as a co-lead investor in two of Germany's most prominent software scale-ups: Celonis and Parloa.

Why this matters

Durable Capital Partners is one of a handful of US crossover growth funds that DACH commentary regularly cites as evidence that late-stage capital for the region's largest software companies increasingly originates outside Europe. Its participation in the funding rounds of both Celonis, Germany's only reported decacorn, and Parloa, one of the country's fastest-scaling AI companies, makes it a useful single reference point for that broader capital-flow pattern rather than a one-off data point.

Company

Durable Capital Partners runs a crossover investment strategy spanning private growth-equity rounds and public-market positions, led by founder Henry Ellenbogen, previously a senior portfolio manager at T. Rowe Price before founding Durable Capital. Public profiles describe the firm's public-equities book as tracked through periodic SEC 13F filings, standard practice for US investment advisers managing public securities above the disclosure threshold; this record does not restate specific holdings or portfolio values from those filings, which change quarterly.

Role in the ecosystem

In the DACH region, Durable Capital Partners recurs specifically at the growth and late-stage layer: Startuprad.io's own coverage documents it, alongside T. Rowe Price, co-leading the decacorn-round financing that valued Munich-based process-mining company Celonis above USD 10 billion, and separately names it as a backer of Berlin-based conversational-AI company Parloa. Parloa's own funding disclosures show Durable Capital Partners as a joint lead of Parloa's 2025 Series C alongside Altimeter Capital and General Catalyst, with continued participation in its 2026 Series D alongside General Catalyst, Altimeter Capital and EQT Ventures.

Selected relationships

Founder, Managing Partner and Chief Investment Officer: Henry Ellenbogen. Co-investor relationship: T. Rowe Price, co-lead of the Celonis decacorn funding round. DACH portfolio companies documented in Startuprad.io coverage: Celonis (Munich, process mining; Durable Capital Partners and T. Rowe Price co-led its decacorn round) and Parloa (Berlin, conversational/agentic AI; Durable Capital Partners was a joint lead of the 2025 Series C alongside Altimeter Capital and General Catalyst, and continued participating through the 2026 Series D).

Startuprad.io relevance

Startuprad.io's own coverage references Durable Capital Partners twice: in a profile of Celonis as part of a series on Germany's unicorns, where it and T. Rowe Price are named as co-leads of Celonis's decacorn funding round, and in a roundup of top AI startups in the DACH region in 2025, which names Durable Capital Partners and General Catalyst as backers of Parloa.

Public source context

Sources reviewed for this record include Crunchbase's and Bloomberg's profiles of Henry Ellenbogen, PitchBook's and Dealroom's investor profiles of Durable Capital Partners, publicly reported coverage of the Celonis decacorn round and Parloa's Series C and D announcements, and the two Startuprad.io coverage items listed below. Fund size and assets-under-management figures for Durable Capital Partners vary across third-party data providers and are not restated here as a single verified figure; readers seeking current AUM should consult the firm's own SEC filings.
