What is Sistava?
Sistava is an AI workforce platform where you hire AI employees and work with them through conversation. Tell an employee what you need in plain language, and Sistava handles the setup behind the scenes, including the tools, context, and team coordination needed for the work. You do not need to learn AI configuration or build workflows first. You can start with the work you want done, stay involved in the decisions that matter, and see how your team is moving forward.
