Case Study: Sierra Wireless achieves 90%+ supplier response and streamlined RoHS & REACH compliance with Assent

Sierra Wireless Growing Better Expanding Business Offerings and Supplier Engagement

Sierra Wireless, an IoT pioneer with ~1,400 employees and $713M in annual revenue, faced growing customer demand for environmental and social compliance data (RoHS, REACH) that their existing tools couldn't centrally manage. To address frequent, complex requests and reduce manual follow‑ups, Sierra Wireless adopted Assent’s solution, implementing the Assent Sustainability Manager to create a centralized compliance data repository and streamline supplier communications.

Assent provided a supply chain sustainability management platform that automated data collection, validation, and reporting while supporting ongoing supplier outreach. The program engaged 400+ suppliers and lifted supplier response rates from ~50% to more than 90% for RoHS and over 86% for REACH, materially reducing manual effort, improving transparency, and enabling Sierra Wireless to expand compliance programs (including a conflict minerals rollout) — demonstrating measurable business impact from the Assent partnership.
