Overview

Sapling is a category defining HR technology platform automating people operations for high growth enterprises. Headquartered in the United States and serving customers across North America, Europe and Asia Pacific, it supports people teams at organisations scaling from a few hundred to several thousand employees, turning fragmented HR workflows into seamless, integrated experiences that scale with ambition.

Business ChallengesWhat Stood Between Sapling and Enterprise Scale
  • Talent Velocity Gap. Roadmap commitments outpaced the speed at which senior engineering capacity could be hired and onboarded.
  • Architecture Debt. A monolithic core that had carried the early product could no longer absorb enterprise load or ship features in parallel.
  • Integration Backlog. Every enterprise deal depended on connectors to HR, payroll, and identity systems the platform did not yet support.
  • Compliance Pressure. Enterprise buyers and acquirers required security and data handling standards the platform had to meet before diligence.
SolutionOne Embedded Team, Four Workstreams

Devsinc embedded senior engineers directly into the Sapling team and ran four workstreams in parallel, closing the capacity gap while rebuilding the platform underneath it.

  • Seamless Team Integration. Engineers embedded into existing squads, working the same rituals, backlog, and standards rather than operating as a separate vendor.
  • Microservices Transformation. The monolith decomposed into independently deployable services, so teams could ship in parallel without contention.
  • Integration Factory. A repeatable connector framework that turned each new enterprise integration from a bespoke project into a predictable build.
  • Security Architecture and Continuous Delivery. Enterprise grade security controls and an automated pipeline, so every release met compliance requirements by default.
Measurable OutcomesWhat the Work Produced
  • Enterprise integrations: 32 Connectors delivered across HR, payroll, and identity systems, expanding addressable market by $50M or more.
  • Deployment time: 75% Reduction in deployment time through continuous delivery.
  • Feature deployment speed: 3x Faster feature deployment after the microservices transformation.
  • Technical diligence: Passed Platform cleared enterprise technical diligence without remediation, central to the acquisition that followed.

The rebuilt platform passed enterprise technical diligence without remediation, and the integration coverage it unlocked was central to the acquisition that followed.
