InfoSum Tech Stack

Privacy-first data clean room for multi-party customer data collaboration

Software Development London, England 51–200 employees Privately Held

InfoSum runs a data clean room that lets companies match and analyze customer data across parties without moving it. Its Go, gRPC and Protocol Buffers core on Kubernetes, spanning AWS, GCP and Azure alongside Snowflake and Databricks, matches a push to run its native app across all five major clouds. Hiring is engineering-led but slow, and a Head of Infrastructure search plus repeated high-load bottleneck pains point to scaling strain.
