Delivering healthcare today means navigating layers of complexity, from administrative burden and regulatory requirements to fragmented infrastructure and operational strain, all while facing mounting pressure to improve outcomes and reduce costs. At the same time, the industry’s ongoing shift toward value-based care has made proactive patient engagement and preventative services more essential than ever.
At Summit Partners, we believe the future of healthcare belongs to businesses that simplify complexity for their customers, including patients, providers and systems. Companies with solutions designed to integrate seamlessly into clinical workflows, reduce administrative friction and prioritize patient care are positioned to redefine what success looks like in healthcare.
The VaxCare Story
VaxCare’s platform is designed to do just that, and the company’s story offers a broader playbook for scaling tech-enabled businesses in healthcare. Casey DeLoach co-founded VaxCare in 2007 with a vision to help physicians modernize their vaccine programs. The company initially focused on supporting small and mid-sized clinics, offering workflow tools to ease the manual, often overlooked processes involved in vaccine delivery like inventory management, eligibility tracking and reimbursement.
At the time of Summit’s 2020 investment, VaxCare had built a strong foundation with a tech-enabled solution that helped practices streamline vaccine administration and improve care consistency. In partnership with Casey and his team, we supported VaxCare as it evolved into an end-to-end platform aimed at addressing the clinical, operational and patient engagement needs of a broad range of healthcare practices, from small independent practices to larger physician groups to national health systems. We worked closely with the team to help expand the platform’s functionality, deepen ecosystem integrations, reposition the company’s go-to-market strategy and build out the senior leadership team to support this next phase of growth.
Today, VaxCare simplifies the vaccination process from procurement and patient engagement to documentation and reimbursement. The platform now supports over 21,000 providers and serves more than 11 million patients across 40+ states.1
The Trends Redefining Healthcare Delivery
We believe VaxCare’s growth is not only a product of strong execution but also reflects broader shifts in how care is delivered, reimbursed and experienced across the U.S. healthcare system. Here, we highlight four trends that helped to fuel VaxCare’s growth and that we believe present meaningful opportunities for other growth-stage companies working to simplify and improve healthcare delivery.
1. Simplifying complexity is becoming a strategic advantage.
As care delivery becomes more distributed and regulated, the administrative burden is rising fast. For many providers, complexity is now a core cost driver. In immunizations alone, practices often manage forecasting, procurement, documentation and billing across disconnected systems, all of which can create costly gaps in patient care. VaxCare’s integrated platform helps eliminate many of these manual touchpoints, allowing providers to focus on delivering care instead of managing logistics.
2. Digitizing provider workflows is a necessity, not a luxury.
Provider burnout and staffing shortages, well-documented in recent years, have made efficiency a clinical imperative. To help address these challenges, the healthcare industry is increasingly embracing automation, particularly in high-friction, repeatable tasks that pull staff away from direct patient care. By digitizing and streamlining key processes like inventory tracking, eligibility verification and documentation, VaxCare’s platform is designed to reduce administrative burden, improve consistency, minimize errors and help ensure patients receive the right care at the right time. In many clinics, VaxCare’s solutions save more than 30 minutes of nurse time per day, enabling teams to spend more time on what matters most—patient care.2
3. Proactive patient engagement is becoming a clinical imperative.
Preventative care is a cornerstone of value-based models, yet many providers lack the tools to close care gaps and effectively engage with patients at scale. VaxCare’s platform is designed to support proactive patient engagement through automated reminders, real-time eligibility verification and adherence tracking. By integrating these capabilities into clinical workflows, VaxCare promotes timely access to recommended care, helping providers to foster stronger patient relationships and drive improved outcomes.
4. Consumer expectations are redefining the care experience.
Today’s patients expect seamless, consumer-grade healthcare experiences, and providers are feeling the pressure to deliver. VaxCare’s patient engagement tools are built into its clinical workflow and designed to enable timely outreach, easy scheduling and improved follow-through, without adding to staff workload. This alignment of convenience and clinical need helps improve adherence and strengthen the provider-patient relationship.

The Takeaway for Healthcare Leaders
The most enduring healthcare companies aren’t just improving efficiency; they’re elevating the quality and accessibility of care. They enable providers to work smarter, engage patients more effectively and deliver better outcomes across their communities.
We believe VaxCare’s journey is a case study in what’s possible when technology, execution and market timing align. For healthcare CEOs navigating today’s shifting landscape, it offers a compelling example of how to scale impact in a complex system.
