Mirox Reviews & Product Details

Mirox is an Amazon PPC bid management platform for sellers, agencies and in-house advertising teams. Most bid tools change your bids and tell you what changed. Mirox tells you why. Every bid decision carries its reasoning with it: the conversion-rate estimate and how confident the model is in it, which alternatives were evaluated, which guardrails were checked, and which constraint ended up binding. You can open any single decision as a Decision Trace, review how a keyword's bids moved over time in the Bid History Timeline, and export the whole chain as a CSV for a client report or an internal audit. For agencies, that is the difference between telling a client ACoS moved and showing them exactly why. Try it without handing over your account. Simulation Mode runs on your live Amazon account in read-only for 30 days. Same account, same ASINs, same auctions, and it changes nothing. At the end you receive every bid Mirox would have set differently from your current setup, the reasoning behind each one, and the CSV. You keep that file whether or not you become a customer, and no card is required to start. Most trials ask you to connect an account and let the tool act on it. This one does not. Under the hood, sixteen specialist agents each own one part of the problem. Bayesian conversion-rate estimation treats zero conversions in eight clicks and zero conversions in three hundred clicks as different evidence rather than the same signal. Inventory-aware bidding throttles spend before stock runs out, protecting the conversion history that a stock-out would otherwise poison. A layered safety system runs above all of it: kill switch, ROAS circuit breaker, spend anomaly detection and per-marketplace gates. Day-parting, placement-specific bid tuning and semantic negative keyword discovery are included. Pricing is a flat monthly fee and never a percentage of ad spend. A tool that takes a cut of your spend earns more when you spend more, and we would rather not have that conversation with our own customers. Prices are published rather than demo-gated. Mirox supports twelve Amazon marketplaces across Europe and North America, is hosted in the EU, and handles per-marketplace thresholds, currencies and multilingual semantics across German, French, Italian, Spanish and UK markets. It was built in Portugal by Amazon sellers, for Amazon sellers.
