How Plum Achieved 75% Faster Enterprise Onboarding 

Plum is a modern insurance platform built for startups and SMEs, helping companies offer competitive health benefits to their employees—without legacy processes or paperwork. But as Plum moved upmarket, its operational model needed to evolve. With more enterprise clients came more complex onboarding needs—especially around syncing employee and dependent data from diverse HR systems. Manual workarounds were no longer enough.

That’s when Plum turned to Tartan.

Scaling with Speed—and Accuracy

For Plum, ensuring a smooth onboarding experience for HR teams is non-negotiable. Every new customer brings its own HR software—some use Darwinbox or Zoho People, others Workday or SAP. The challenge? Each integration used to require weeks of engineering effort, not to mention back-and-forth coordination with HR teams for Excel dumps or manual audits. Even small data mismatches led to incorrect policy issuance, missed endorsements, or support tickets that cost time and trust.

As the client base grew, so did the load on Plum’s operations and engineering teams. The model wasn’t scalable. “We realized we were spending too much effort building integrations client by client,” noted a senior operations lead. “We needed a way to make HR data syncing fast, accurate, and hands-off.”

One Unified API. Instant Coverage.

Plum integrated Tartan’s HyperSync—a unified API layer that connects securely to over 50 HRMS and payroll systems. In just 48 hours, they launched a real-time sync flow that pulled verified employee and dependent data straight from the client’s HR system.

This meant no more custom builds. No more onboarding delays. And critically—no more data errors. Tartan acted as the middleware that handled the complexity, abstracting dozens of integrations behind one stable interface.

Tartan also ensured that every data transfer was secure and compliant, with encryption and consent built-in. That gave Plum’s enterprise customers peace of mind—knowing sensitive employee information was being handled with care.

A Platform Built to Scale with Clients

The impact was immediate. What previously took six weeks—scheduling dev cycles, building a connector, debugging edge cases—now took less than two days. New clients could be onboarded with minimal lift. HR teams didn’t need to send CSV files or chase down dependent information. Mid-policy endorsements that used to be error-prone became automated and reliable.

Since integrating Tartan, Plum has been able to onboard enterprise clients 75% faster and achieve 100% accuracy in mid-term policy updates. That’s not just better operations—it’s a better customer experience.

“Tartan helped us automate what used to be a painful, manual process. We now onboard enterprise clients in days—not weeks.”

By using Tartan’s Unified API, Plum turned a scaling bottleneck into a growth advantage—freeing up engineering bandwidth, reducing onboarding friction, and delivering a more professional experience to enterprise clients. For a company where trust and timing matter, that change has been transformative.
