Service as Software
Traditional software hands you a tool and leaves the work with your team. Service as Software delivers the outcome: AI agents carry out the steps, and people approve the points where a decision matters.
Specialized agents, each with one role and restricted tools
Mandatory human approval at decision points
An auditable record of everything the system did
