Who built Moonwalker
What Max does
Moonwalker is advertising and profit analytics software for Amazon sellers and brands. Max is the agent that operates it on your account.
Max works out the profit of every ASIN and every parent listing: sales, less Amazon's referral and fulfilment fees, refunds, VAT where it applies, ad spend and your cost of goods. The result is a break-even for each product, and every bid is held against it. You enter your cost of goods. Every other figure comes from your own Amazon account.
For brand-registered sellers, Max reads Amazon's Search Query Performance data: the searches shoppers use, the impressions, clicks, cart adds and purchases each one brings, and your product's share of them. Max compares your conversion on each search with the average for that search, and shows you which searches your product wins.
Sessions, units, orders and conversion rate per child ASIN per day, so a change in sales is traced to traffic or to conversion.
A bid for each keyword and placement, set from that keyword's own conversion and the product's break-even, and moved in small daily steps.
When a product runs low or out of stock, Max proposes lowering or pausing its ads, and turning them back on when stock returns.
Searches that spend without selling are proposed as negative keywords. Searches that sell are proposed as keywords of their own.
Once a week, for each account: sales, profit, ad spend, what Max changed and why.
Method
Max does not improvise. Max follows a written method, and the method is checked before it is allowed to act.
The method comes from the founders of Moonads, who have built 8 Amazon brands of their own and manage advertising for other brands every day. Their rules for bids, placements, negatives, launches and stock are written down as explicit calculations.
Each rule is checked against real account history, then run in a dry run, where its changes are listed but not applied, before it may change anything.
Code does the arithmetic, so the numbers are exact. AI models read listings and search terms, plan the work and explain each change in plain words. The Moonads team watches the system and keeps improving the method.

In development
Max is being built to connect through the Model Context Protocol (MCP), the open standard that AI assistants use to work with outside tools. You will be able to ask Max about your account, read the log and approve changes from the assistant you already use.
This is not available yet. We will say so here when it is.
Who is behind Max
Moonwalker is built and operated by Moonads, a trading name of Inkululeko S.L., Calle Pléyades 17, 28222 Majadahonda, Madrid, Spain. It was created by two Amazon specialists who have managed advertising for brands on Amazon for more than three years and built 8 brands of their own. Moonads manages Amazon advertising for brands in North America and Europe, and Moonwalker is the system its own team works with every day.
In that time the accounts Moonads manages have sold more than $100 million on Amazon, and the founders' own brands have sold more than $40 million. Moonads manages about $4 million of Amazon advertising a year. Moonwalker suits sellers and brands, FBA or FBM, that spend from about $1,000 a month on Sponsored Products. Search query analytics needs Amazon Brand Registry.
