Long-term investment firm putting family and individual capital into industrial businesses

Private investment firm with offices in New York and London backing healthcare technology and other companies

Aquiline, formally Aquiline Capital Partners, was founded in 2005 and describes itself as a private investment specialist in financial services and technology, with offices in New York and London. It looks for companies where financial services is at the core of the business and where technology can change the way the work is done. Its stated approach has three parts: deepen its knowledge of the financial services and technology landscape, understand the main operational problems facing the organizations in it, and then identify and invest in the companies that offer answers through promising technology, services, talent and values.
Its investors are grouped into practices, so that each team follows one market closely. The practices named on the site are:
Earlier descriptions of the firm named financial services and technology, healthcare and business services as its three broad areas, which fits the same list.
The site describes two investment lines. The first covers established businesses in a wide range of enterprise values, plus add-on acquisitions of any size, where it may take a majority or a minority position. The second targets younger businesses that already have recurring revenue and generally involves minority positions. Alongside the equity work it offers strategic capital that finances growth, including loans secured against recurring revenue, senior and junior debt, and preferred or structured equity.
An announcement the firm published in 2022 shows what its ownership looks like in practice. It had backed Aspirion, a provider of technology-enabled revenue cycle management for hospitals and physicians, which specializes in complex claims such as those tied to motor vehicle accidents, workers' compensation and military health programs, as well as revenue integrity for clinically complex claims. A healthcare-focused private equity firm agreed to buy a majority stake, and Aquiline said it would stay on as an investor with the management team. It credited the platform's growth to investment in people, technology and strategic acquisitions.
The firm says its culture is built around its mission, and that it prizes tenacity, creativity and forthrightness.
