About the Project:

The Project is a fast-growing UK-based startup building a next-generation acceleration engine for Apache Spark, used in large-scale data infrastructure worldwide.

At petabyte scale, even small inefficiencies in data processing translate into massive infrastructure costs. The Project is solving this by developing a novel engine that dramatically accelerates Spark workloads without requiring changes from data teams.
