What Kain Capital buys
Kain Capital is a New York private equity firm focused on healthcare, with an emphasis on using technology to change how care is delivered. It backs stable, founder-led companies with $20 million to $150 million or more of revenue and $5 million to $40 million of EBITDA. It ideally takes control, holding 60% to 85% of a company, and in some cases takes a protected minority stake of 20% to 49%. It wants founders who stay involved, and it will also back early-stage companies that can use its platform.
Its five focus areas are value-based primary care, hospice and palliative care, occupational medicine and workers' compensation, specialized behavioral health, and healthcare technology. In 2026 it added White Wilson Medical Center, a Florida multi-specialty group, and RadX, a 26-center radiology network. The range runs well above the lower middle market, so a company near the $5 million floor sits at the small end of what Kain considers. A smaller practice is more likely to meet Kain as an add-on to a platform such as Agile or Luminos.

Greymont’s take
How Kain Capital fits a seller
Kain suits a healthcare founder who wants to stay active and needs technology, data and recruiting help as much as money. The firm looks for owners who remain involved, it adds senior managers, and its Kain Analytics team builds data and automation tools for portfolio companies. Its ideal 60% to 85% stake still leaves the founder with a real share of the company.
Kain says most of its investors are long-term capital and that it is not tied to a set return horizon, so an owner should ask directly how long it expects to hold the business. In 2024 the firm said it does not use debt in its investments, which may appeal to a practice wary of leverage. Ask whether that still holds. Owners should also ask how much of the plan depends on moving to value-based contracts.
Questions owners ask
What size healthcare company does Kain Capital look for?
Its criteria call for stable revenue of $20 million to $150 million or more and EBITDA of $5 million to $40 million. It also says it will invest in early-stage companies that can use its platform.
Does a founder keep a stake after Kain invests?
Usually. Kain ideally holds 60% to 85% of a company, in some cases takes a protected minority of 20% to 49%, and looks for entrepreneurs who want to stay actively involved.
Which parts of healthcare does Kain focus on?
Five areas: value-based primary care, hospice and palliative care, occupational medicine and workers' compensation, specialized behavioral health services, and healthcare technology. In June 2026 it also completed an investment in RadX, a radiology network.
Does Kain Capital use debt in its deals?
In an April 2024 release it said it does not use debt in its investments, so that capital can go toward growth and quality of care. Owners should confirm that still applies to current deals.
