Span Brain LLC is a small, distributed company from Georgia, building both open AI infrastructure and calm, human-centred software.
We watched the software market split in two unhealthy directions at once — AI tooling captured behind a thousand closed silos, and human-facing apps optimised to extract attention rather than respect it. We started Span Brain to refuse both: open, auditable infrastructure on one side; calm, private, human software on the other.
We ship in public, version openly, and keep our servers and SDKs as source even when clients stay closed. Decisions are documented; AI actions are logged; data lives on nodes the operator owns. Nothing important runs in a black box, including how we run ourselves.
A senior crew across infrastructure, security, AI research, and the quieter craft of emotional design — distributed across several time zones, holding the line on quality and calm. We hire slowly and on purpose.
Three rules that shape every product decision.
Servers and SDKs ship as source. No black boxes, no opaque licenses, no surprise telemetry.
Decisions are logged, actions are reversible, and what software does to your data stays inspectable.
Self-host or cloud — your data, your nodes, your keys, your call. We just supply the tools.
