Roslin Tech Stack

Call center and dispatch platform for transportation operators

Ground Passenger Transportation New York 201–500 employees Founded 2018 Privately Held

Roslin operates a call center and dispatch service for transportation providers, with a dual tech footprint: iOS/Android mobile apps (Swift, Kotlin, REST, gRPC) powering real-time trip experiences and fleet tracking, and a backend stack (Go, PostgreSQL, Kafka, Google Cloud Spanner) handling dispatch coordination and operational messaging. The project list—real-time trip surfaces, location telemetry, live activity integration—signals a shift from pure call-center services toward direct passenger and operator app experiences. Pain points around real-time trip reliability and high-performance system optimization suggest they are scaling beyond voice support into software-driven operations.
