The people building Stacklume.
Engineers, researchers, and operators who built the controls they now ship. Backgrounds from AWS, Google Brain, In-Q-Tel, and the US federal cyber community — all focused on one problem: making trust explicit at the foundation of modern systems.
Where it starts
Stacklume began with one conviction: trust should be a system, not an accident.
Randall Scott Avenell
Founder & CEORandall founded Stacklume to make trust explicit at the foundation of modern systems. He has spent his career building secure platforms across cloud, identity, and compliance — and started Stacklume to give teams a single source of truth for who can access what, and why.
As CEO, he leads product direction, go-to-market strategy, and the engineering culture behind the platform. He holds the conviction that identity is the last security primitive most organizations still get wrong — and that the window to fix it is closing fast.
The bench
Operators who'd rather be in the diff than on the panel. Each one has built the system they now ship.
Built model-platform infrastructure at Google Brain, then led ML safety engineering at a frontier lab. Brings a systems-first approach to AI trust — the kind that survives production at scale, not just a research paper.
Federal cyber background across classified and unclassified environments. Led AI red-teaming programs for a major US agency before joining Stacklume. Knows what adversaries actually do — not just what they say in conference talks.
Built and scaled enterprise security go-to-market teams across two prior unicorns, taking both from sub-$10M ARR to category leadership. Deep relationships across the CISO community in financial services and healthcare.
Adversarial ML researcher with 38 peer-reviewed papers across NeurIPS, ICML, and USENIX. Former MIT CSAIL. Leads the research agenda that turns academic adversarial findings into production-hardened platform defenses.
The operator's operator. Has scaled three security companies from Series A to public exits, owning cross-functional execution at each stage. Runs the internal operating system that lets Stacklume ship fast without drift.
