Choosing the right benefits partner in a complex vendor ecosystem 

With the health benefit trend bending upwards, employers face heightened pressure to manage costs while still responding to employee and plan member needs. In a recent Mercer survey, a top-three priority for employer health plan sponsors is measuring the performance of their health programs to ensure they are providing value.

That’s getting harder to do. The health vendor ecosystem has expanded rapidly, driven in large part by venture capital investment in digital health and ongoing mergers and acquisitions. After pandemic-era investment peaked at $29.1B in 2021, funding declined to $15.3B in 2022 and $10.7B in 2023, then stabilized at $10.1B in 2024. In 2025, investment rebounded to $14.2B. This cycle has accelerated new product launches, capability expansion and consolidation.

Many vendors that entered the market as single-condition point solutions now offer broader capabilities such as care navigation, provider network partnerships, medication management, referral pathways and clinical oversight. As a result, employers often see multiple partners offering similar services across prevention, treatment and recovery. This overlap increases the risk of duplicative costs, inconsistent member experiences and unclear accountability for outcomes.

In this environment, employers need selection and performance approaches that reflect how solutions work together, not only how each solution performs on its own.  A structured ecosystem review helps employers find opportunities amid the complexity, by making it clear which partner owns which part of the member journey, what each program is expected to deliver and where budget is being spent twice for similar services.

Why standalone ROI reviews can miss the real issues

As solutions intersect, employers may struggle to measure and evaluate performance, attribute outcomes and defend ROI. A vendor’s reported savings may reflect the influence of other partners that touch the same member population or clinical pathway. Overlap can also introduce operational issues that reduce impact even when each vendor meets its own contract terms. Evaluating the ecosystem as a system helps employers distinguish between true incremental value and activity that is redundant, shifting ROI discussions from competing vendor claims to evidence-based investment decisions.

Common issues in complex ecosystems include competing engagement funnels for the same population, multiple navigation layers that create friction and confusion, referral leakage when handoffs are unclear, inconsistent data capture across vendors and challenges attributing outcomes when several programs influence the same result. Addressing these issues has practical outcomes: fewer duplicated outreach and administrative processes, clearer ownership for handoffs and a smoother experience for members who are trying to access care without being bounced between programs.

Let’s take the example of an employer that offered a condition management vendor; nurse-line support through the health plan; and a wraparound care navigation platform. These solutions were engaging the same population and providing overlapping triage and referral support, often without consistent coordination, and attributing similar services and outcomes to the same members. Rather than evaluating each vendor independently, the employer conducted an ecosystem review to clarify roles across the care pathway. They assigned navigation and triage to a single partner while redefining the condition management vendor’s scope to focus on clinical intervention and outcomes. This reduced duplicative outreach, improved coordination and created a more streamlined pathway into care for members. It also enabled the employer to more accurately attribute outcomes.

Delivery models are also changing. Employers increasingly see digital health capabilities embedded within carrier offerings and PBM platforms, creating multiple points of entry for members. Embedded access can improve reach but it can complicate governance, referral management and performance measurement, particularly when data and workflows sit inside another partner’s system. An ecosystem approach helps employers preserve visibility and control by clarifying who is responsible for member communications, clinical protocols, referrals and reporting across embedded and stand-alone solutions.

A structured approach to selecting vendors in a crowded ecosystem

Vendor selection is no longer only a portfolio exercise. It is an ecosystem design exercise. Employers can strengthen decisions by clarifying the intended role of each partner and testing how partners will work together in practice. The benefit is not just a cleaner vendor list, it is a benefits program that is easier to run, easier to explain to members and easier to measure, which improves confidence in ROI decisions and supports stronger long-term value realization.

Key actions include:

• Clarify the role each solution plays across the care pathway, including engagement, navigation, care coordination and clinical delivery
• Identify where multiple partners engage the same population at similar moments in the member journey
• Map how referrals and handoffs occur between vendors, carriers and PBMs and confirm who owns the handoff process
• Confirm integration requirements and data flows, including how eligibility, utilization and outcomes data will be shared and reconciled
• Evaluate how outcomes will be measured when more than one solution influences the same clinical pathway and document an attribution approach

Employers should also pressure-test whether a vendor’s expanded capabilities create overlap with existing partners. Capability expansion can improve the product, but it can also dilute accountability if roles are not clearly defined. Making roles explicit enables employers to hold the right partner accountable for specific deliverables, reduce duplication across vendors and avoid paying for the same navigation or coaching function multiple times.

Building on the employer example above, identifying overlapping services across a condition management vendor, nurse line and navigation platform created opportunities for cost reduction. The employer was paying separate per-member fees for each solution, even though they provided similar coaching and outreach capabilities. By consolidating navigation and outreach within a single partner and eliminating duplicative services (such as overlapping nurse line support), the employer reduced redundant program fees while improving clarity in the member experience. While cost reductions will vary based on the extent of overlap eliminated, in this instance, savings amounted to about 15% of prior spending on the three programs.

Measuring performance to ensure the program is working as designed

Given the pace of change, employers benefit from ongoing ecosystem review rather than one-time selection decisions. A practical measurement model includes both outcomes reporting and operational checks to confirm the program is working as designed.

When evaluating the vendor ecosystem, employers should:

• Review program cost, impact and opportunities to improve value extraction on a regular basis
• Assess data visibility across programs, particularly when services are embedded within plan-aligned partnerships
• Define performance metrics that reflect incremental value, not duplicated activity already addressed by other partners
• Audit user experience pathways and program operations through case reviews and documentation to validate that member interactions align with the intended model
• Reassess vendor alignment periodically as mergers, acquisitions and feature changes shift responsibilities and integration needs

In a crowded vendor ecosystem, employers improve results when they define clear roles, manage overlap and measure performance across the full member journey. The outcome is a more coordinated vendor model with clearer accountability, less duplication, a more consistent member experience, stronger decision support for ROI and greater value realization from digital health and point solution investments.
