A research-weighted team
The engineering group includes PhDs alongside senior developers. The work skews toward the parts of ad tech that are genuinely difficult — data structures, decisioning, and the systems underneath them.
About AdKernel
Founded in 2009 out of a custom development practice, AdKernel is privately held, independent, and 55+ people strong. It stays engineer-driven: the roadmap answers to the people running on the platform, not to an owner elsewhere.

Most of what the team builds exists because something had to hold up at request volumes where ordinary approaches stop working. That constraint shapes the platform more than any product decision does.
Infrastructure built for our own platform gets released publicly rather than kept private, where it stands or falls on its own merits in front of other engineers.

ActiveJ is the high-performance Java framework underneath the platform, written after mainstream frameworks could not hold the throughput the business needed. It is open source and independently benchmarked for high-volume data processing and big-data workloads.
It is also the clearest evidence of how the team works: the hard parts get built properly and then published, rather than described in a slide. See the technology or visit activej.io.
Co-founder & CEO
Eugene and his co-founder met in a nuclear physics program in Ukraine, which is a large part of why the company is built the way it is. His first venture, Trustename, was a full-featured online ad-serving platform, and it became the foundation for much of what AdKernel builds today.
