Introducing Sinch
Sinch, a global leader in customer communications (CPaaS) serving 175,000+ businesses, faced localization bottlenecks due to limited internal language staff and coverage gaps. By adopting a fractional language team embedded as in-house members, Sinch reduced localization costs by 25% and achieved 100% utilization rates, enabling scalable, efficient multilingual support aligned with business growth.
Background
Sinch had a mature localization program with a robust TMS and senior manager. The need for more flexible language coverage grew after a key specialist’s promotion, prompting a search for scalable support to augment rather than replace internal resources.
The Problem
Single-person-per-language staffing limited scalability and risked delays during absences. External agencies lacked integration, affecting quality and consistency, blocking rapid multilingual releases.
The Solution: Fractional Language Team
A flexible team, rather than a single individual, was fully integrated into Sinch's internal workflows and tech stack. This model provided on-demand scalability and continuity.
