The secure foundation where trust begins.
STACK Vault is the trust and identity platform that secures what matters most — identities, credentials, policies, and access — for the systems organizations rely on. Every product we build sits on this foundation.
Three convictions we don't compromise on
We hire, build, and sell against these. They're load-bearing for everything that sits on top of STACK Vault.
Trust is a system, not a feature
Identity, access, and credentials don't get bolted on after the fact. STACK Vault makes trust explicit at the foundation so everything above it can be calm, controlled, and intentional.
Clarity over noise
Security tools fail when teams can't see what they own. We illuminate complexity instead of hiding it — so operators understand exactly who can access what, and why.
Reversibility by default
Anything STACK Vault enforces must be undoable in seconds. Strong foundations don't lock you in — they give you the confidence to move.
How we got here
STACK Vault was founded by engineers who watched every modern breach trace back to the same place — broken trust at the foundation.

Founded by veterans of AWS Security, Google Brain, Lacework, and federal cyber programs — operators who saw identity-led incidents from inside the trenches.
Year OneSeries A in 2025
$24M led by category-defining investors. First 30 enterprise customers deploy STACK Vault as their identity and trust core.
Year TwoSeries B in 2026
