Scalac Tech Stack

Scala and event-driven systems consultancy for fintech, healthtech, and startups

IT Services and IT Consulting San Francisco, California 51–200 employees Founded 2014 Privately Held

Scalac is a 51–200-person software consultancy founded in 2014, focused on Scala, Akka, and reactive systems architecture. The tech stack is heavily specialized—Scala, Akka, ZIO, Spark, and event-driven infrastructure (Kafka, RabbitMQ, CQRS)—with no adopting or replacing signals, suggesting deep domain focus rather than technology churn. Active projects span performance optimization, technical debt refactoring, and a live broadcast platform, while hiring remains mid- and senior-weighted across engineering, indicating a mature team scaling client delivery rather than rapid headcount expansion.
