A focused partner for healthcare
business owners

Harborline Health Partners is a healthcare-focused private equity firm pursuing acquisitions of founder-led and family-owned healthcare businesses across the United States.

We bring a flexible and patient approach to every transaction — prioritizing alignment with founders, thoughtful deal structures, and a genuine commitment to building enduring businesses rather than extracting short-term value.

Our focus is narrow by design. We have spent our careers investing in healthcare businesses across the lower middle market. We are not generalists dabbling in healthcare — this is all we do.

"We seek out businesses built on a foundation of quality care and trusted relationships — and partner with their founders to build something more enduring."

Harborline was founded by a healthcare investor with nearly a decade of experience at two institutional private equity firms — Galen Partners and Affinity Partners — collectively managing over $6B in assets under management. That experience is the firm's core competitive advantage.

A focused strategy built on
sector expertise.

We pursue acquisitions of founder-led healthcare businesses where our deep sector knowledge, institutional experience, and flexible approach to capital create a differentiated advantage for both buyers and sellers.

Our investment universe spans the full healthcare landscape — from services and technology to medical devices and life sciences — wherever we find durable businesses with strong fundamentals and the potential to grow with the right partner.

We are not defined by a single sub-sector, payer mix, or business model. We are defined by our expertise in healthcare and our conviction that the lower middle market remains significantly underserved by dedicated, sector-focused capital.

"Healthcare is not one market — it is many. Our edge is the breadth of experience to recognize value across the spectrum, and the focus to act decisively when we find it."

We target businesses with $10M+ in revenue and $2M+ in EBITDA, and are flexible on deal structure — prioritizing alignment with founders over rigid process. We evaluate opportunities nationally, with an initial pipeline concentrated in the Southeast.

What we look for

We are straightforward about what we seek. If your business fits this profile — or is close to it — we want to hear from you.

Ownership Profile

Founder-owned or family-owned businesses. We are particularly well-suited to serve as the first institutional capital partner — bringing structure and resources without disrupting what makes the business great.

Revenue & EBITDA

Revenue of $10M or more and EBITDA of $2M or more. We are flexible on these thresholds when the business has clear growth momentum or a compelling platform opportunity.

Business Quality

Established operations with a track record of quality care, strong referral relationships, and a recurring or contracted revenue base. We prioritize reputation and clinical integrity.

Sector Focus

Healthcare businesses across services, technology, and life sciences — including home care, behavioral health, physician services, medical technology, pharma services, and healthcare IT.

Geography

We are sector-focused rather than geography-constrained. While our initial pipeline is concentrated in the Southeast, we evaluate attractive opportunities nationally.

Transaction Flexibility

We are flexible on timeline, structure, and deal size. We can move quickly with minimal friction — no investment committees, no lengthy approval chains — and tailor structures to meet seller needs.

Where we invest

We invest across the full healthcare landscape — from services and technology to medical devices and life sciences — wherever founder-led businesses are building durable value.

Healthcare IT

Software and data businesses that power healthcare operations and decision-making — including electronic health records (EHR), revenue cycle management (RCM), clinical decision support, care coordination platforms, population health analytics, and healthcare cybersecurity.

Healthcare Services

Businesses delivering patient care and support services across the continuum — including home care, behavioral health, hospice and palliative care, physician practice management, ambulatory and outpatient services, senior care, value-based care, and occupational health.

Medical Technology

Medical devices, diagnostics, and equipment businesses — including point-of-care diagnostics, surgical instruments and tools, monitoring devices, imaging technology, and durable medical equipment (DME) manufacturers and distributors.

Pharma Services

Contract and specialty pharmaceutical services businesses — including specialty pharmacy, compounding pharmacy, contract research organizations (CROs), regulatory consulting, clinical trial support, and pharmaceutical distribution and logistics.

Tech-Enabled Provider Services

Technology-driven businesses that enhance the delivery of care — including telehealth platforms, remote patient monitoring, AI-assisted clinical tools, digital therapeutics, and virtual care models that extend provider capacity and improve patient outcomes.

Tech-Enabled Payor Services

Technology businesses serving health insurers and managed care organizations — including prior authorization automation, claims processing, member engagement platforms, utilization management tools, value-based care analytics, and healthcare payment integrity solutions.

How we partner
with owners

We are not financial engineers. We are operators and investors who understand how healthcare businesses actually work — the staffing dynamics, the regulatory requirements, the payer mix sensitivities, and the human relationships that underpin care delivery.

When we acquire a business, we work alongside management to build something more durable — not extract value and exit. We are patient, long-term-oriented, and willing to invest in the talent and infrastructure required to scale responsibly.

  • Equity co-investment structures alongside institutional partners for platform acquisitions where scale economics justify additional capital
  • Flexible deal structures including earnouts, rollover equity, and seller notes — designed to align incentives and ease ownership transitions
  • Retained management teams whenever possible; we invest in people, not just assets

Indicative Transaction Parameters

Target Enterprise Value $5M – $30M+
Revenue Range $10M+
EBITDA Range $2M+
Equity Co-Investment EV $4M – $30M+
Deal Structures Cash, Rollover, Earnout

These are illustrative parameters. We evaluate opportunities on their individual merits and will consider businesses outside these ranges when the fit is compelling.
