Holon for agencies · Early access

Run AI agents for every client. Keep each one under its own rules.

Holon sits between your agents and the tools they use. Each client gets a key, a monthly budget and approval rules. Your team approves what matters. Each client gets a monthly report of what the agents did and what it cost. It runs on your own computer or server.

Your agents are working. Your clients are starting to ask questions.

How it works

  1. 1

    Add a client

    Name it and set its monthly AI budget. Holon gives it its own key and its own rules: what its agents may use, and what must wait for a person.

  2. 2

    Connect your agents

    Put the client's key into Claude Code, n8n or any tool that calls an API. Connect your own MCP servers (your CMS, your CRM) once: their tools become available to your clients' agents, and to nobody else.

  3. 3

    Approve what matters

    Publishing, sending an email, anything above a cost you choose: it waits. Your team gets an email or a Slack message and decides in Holon, with one key.

  4. 4

    Report and rebill

    At the end of the month, send each client its report by link, and export one line per client for your invoices, with your markup.

Built for how agencies work

Per clientKeys, budgets, rulesEvery call is attributed to the client whose key made it, and checked before it runs against that client's budget and rules.
ApprovalsA person decidesActions like cms.publish always wait for someone on your team, whatever they cost. Email and Slack announce them.
Client reportProof of the workWhat ran, what was blocked, who approved, what it cost, and how AI was used, in plain sentences. A link you can revoke.
RebillingOne line per clientAgent costs, model costs, your markup and what to bill, exported as a CSV. Amounts are exact, never rounded.
Model costsRead per clientAnthropic costs read from your organization's cost report, per workspace. Other providers entered by hand.
Your toolsPrivate MCP serversYour own tools behind the same keys, budgets and approvals, without publishing them.
TeamRolesAdmins, members and viewers. Removing someone or changing their role takes effect at once.
Your dataOn your machineHolon runs where you install it. It keeps who called what, when and for how much, not what the agents read or wrote. Security.

What your client receives

A page you send by link each month, printable as a PDF. Built from the record of every call, so it says only what happened.

  • The agents and tools used, their runs and their cost.
  • Every action that waited for a person: why, the decision, and who made it.
  • The month's AI cost: agents, and models by provider.
  • How AI was used, in sentences your client can put in front of their own boss.

Questions

Is Holon a SaaS?

No. Holon runs on your own computer or on your own server, and your clients' data stays there. Holon the company never receives it: there is no account on our side, and nothing is sent to us.

Which AI tools does it work with?

Anything that can call an API or an MCP server: Claude Code and Claude Desktop, n8n (with the Holon node), Make, Zapier, your own scripts. Your agents use the client's key, and every call they make counts for that client.

Does it replace n8n or Claude?

No. They keep doing the work. Holon sits in front of the tools and agents they call, applies each client's rules, and keeps the record your reports are built from.

What happens when a client's budget is reached?

The next call that could go over is blocked before it runs, and the reason is shown: "Blocked: this would go over Dupont Bakery's $200 monthly budget." You raise the budget in one field, or wait for next month.

Who approves actions?

Anyone on your team with the member or admin role. They get an email and, if you connect it, a Slack message, then decide in Holon. The client's report shows who approved what.

What does my client see?

A report page you send by link: what the agents did this month, what was blocked or approved and by whom, what it cost, and how AI was used. Never your markup. You can revoke every link at any time.

How do you know what the models cost?

For Anthropic, Holon reads your organization's cost report per workspace, every hour: give each client its own workspace. Costs from other providers are entered by hand, per client and month.

What does it cost?

Nothing during early access. After launch, a yearly license by number of clients, free up to 2 clients. See pricing.

What does it run on?

Windows, macOS and Linux (it needs Node.js). On a computer it opens in its own window; on a server your team uses it from the browser. Early access includes help to set it up.
