Membrane

For fractional operators and agencies

We build a live model
of your client’s business. For free.

Every business has millions of data points. We turn them into one model of the business: what’s happening, and what’s coming.

One person who builds the model for each of your clients, checks every number against the client’s own records, and reviews each suggestion before it reaches you. Accountable for the result.

You’ve taken something very complex and not only provided a solution but also presented it in a way that’s very clear.

The deal

You get

  • The live model of the business for each of your clients.
  • Suggestions for improving the business, which you take credit for.
  • A 10% referral fee for any work that goes our way.

We get

The tasks the model suggests that you don’t want to do yourself. Each one is a job at a fixed price from our catalog, paid by your client per shipped deliverable.

How it works

  1. 01

    Connect your client’s systems

    Amazon Seller Central, Shopify, ads, accounting. You connect them if your login can authorize apps on their account. If not, the client approves one consent screen, which names the permissions.

  2. 02

    We build the model that matches your mental model

    The same products, channels, costs and cycles you already use when you think about the business, built from their data. First numbers within a week; the two-year history fills in behind them.

  3. 03

    You use the model and get suggestions

    Every number, forecast and what-if is yours to decide with and to show the client. The model also produces suggestions, each reviewed by a Membrane operator before it reaches you.

  4. 04

    You refer us the tasks you don’t want to do yourself

    Some suggestions are work: a transfer to arrange, listings to fix, a returns process to run. Each is a job with a fixed price on membrane.agency/jobs. Refer it, and we do it. You earn 10% of what the client pays.

FAQ

Do you contact my client?

Only if you introduce us. Suggestions go to you, not to the client.

Why is it free?

We earn on the jobs you refer. The model is how those jobs get found.

Who connects the accounts, and what does my client see?

You do, if your login can authorize apps on their Seller Central or Shopify. Otherwise the client approves one consent screen, which names the permissions. Membrane appears in their list of authorized apps. Either of you can revoke it any time.

Do you change anything in my client’s accounts?

No. The model only reads. A job you refer changes only what its deliverables say, and every action is logged with its reason.

How does the referral fee work?

You earn 10% of what the client pays for the jobs you referred, for as long as they run.
