Who the program is for

  • Agencies

    Run AgencyOS for client teams, or build an operating system around a service you already deliver.

  • Consultancies

    Turn the operating model you design for a client into a system their people run every day.

  • Systems integrators

    Implement AgencyOS, LegalOS or a Custom OS inside the client’s stack and operate it over time.

  • Private equity

    Roll out AI operating systems across your portfolio companies, with the same controls, audit logs and approvals in every company.

Scope it, implement it, run it.

You own the client relationship and the implementation. Stackmint provides the operating systems, the platform and the governance underneath.

  1. 01

    Scope

    Map the client’s services, playbooks and approval points to an operating system, on real work.

  2. 02

    Implement

    Configure AgencyOS or LegalOS, or build a Custom OS on the Stackmint platform from the client’s playbooks.

  3. 03

    Run

    Operate the system for the client: update playbooks, add specialists and workflows, and keep approvals in the right hands.

Everything every OS runs on.

Every client you serve gets the same platform and the same controls, whichever operating system you implement.

  • Ready-made operating systems

    AgencyOS for marketing agencies and LegalOS for law firms, ready to configure for each client.

  • The platform for Custom OS

    The same building blocks behind every OS: specialists from playbooks and workflows with approval gates.

  • One governance layer

    Human approval, immutable audit logs, kill switches and budgets per run, for every client you serve.

  • A branded client portal

    Requests, quotes, approvals and invoices in one place, with delivery in the portal, Slack, API or as MCP tools.

  • Fully hosted

    Stackmint runs the infrastructure. You and your client focus on the work.

  • Client data isolation

    Each client has its own context. Documents are treated as content, never as instructions.

Build the operating system your client runs on.

When a client’s service is not marketing or legal work, build their OS from the same building blocks, around their playbooks and their clients.
