The AI that shows its work.
Autonomous Amazon PPC for European sellers. Watch every bid the AI would make in Shadow Mode — free, no card, your real account, read-only. Then decide.
A new category
We call this Autonomous PPC Intelligence.
Not a dashboard. Not a rules engine. A workforce of 16 specialist agents that bid, monitor, and explain — every decision on the record.
Stop trusting Black Boxes
with your capital.
Legacy "AI" tools hide their logic behind generic status updates. Our Glass Box architecture exposes the exact mathematical proof for every single decision made on your account.

The algorithm decided."
The three pillars
Three things you should be able to demand from any AI managing your spend.
Transparency
Every decision, on the record.
Black-box AI is a trust problem with your capital. Every bid Mirox places carries a full mathematical trace — inputs, alternatives ruled out, the safety gates it cleared. Exportable as CSV.
Safety
Seven layers between the AI and your money.
Kill switch. ROAS circuit breaker. Spend circuit breaker. SP-API fault gate. Optimistic locking. Recovery floor. Marketplace gates. The Sentinel agent sits between every bid and your account.
Intelligence
Real models, not rules dressed up as AI.
Sixteen specialist agents — Strategist, Tactician, Sentinel, Semantic, and twelve more — run Bayesian inference, Thompson sampling, and asymmetric semantic embeddings. Smart from hour one.
Preview the AI. Then trust it.
No vendor in this category will let you see the actual decisions an autonomous system would make on your account before you pay. We will. Free, indefinitely, on your real data.
Connect
OAuth into Amazon Ads. Five minutes. No credentials stored on our side.
Watch
Mirox shadows your account, read-only. Every bid the AI would have placed, traced and explained, side-by-side with what your current setup did.
Decide
Compare the AI's decisions to yours, for as long as you like. Flip live with a switch — or stay in Shadow Mode forever. It's free either way.

How we compare
The rows where we sit alone.
Verified from public pricing pages and analyst reports. No competitor offers Shadow Mode at any price — and EU-native is genuinely empty space in this market.
Verified 2026-04-29 from vendor pricing pages, G2, Capterra, and industry analysts. We'll update at every major competitive shift — and credit the source.
EU-native
Built in Europe, for European sellers.
Not a US tool with a translation layer. Mirox runs on EU infrastructure, handles per-marketplace currencies and rate limits at the source, and ships with multilingual semantic from day one.
Marketplaces supported
7 / 7
Per-marketplace thresholds
ROAS targets, spend caps, and circuit breakers tuned per region — not one global setting bolted across seven markets.
Native currencies, native rate limits
EUR, GBP, USD, JPY handled at the source. SP-API rate limits enforced per marketplace, not blended.
Multilingual semantic
Asymmetric embeddings trained on DE, FR, IT, ES, EN, JA. Your German keywords don’t get matched against English intent.
Sellers running cross-marketplace copy without per-region tuning report a +28% ACoS hit on average. One €399 plan covers up to three marketplaces — with thresholds set per market, not blended.
The math
Find the waste before you pay a cent.
SaaS PPC research puts wasted spend at 30–40% of the average Amazon ad budget. Shadow Mode shows you yours — for free, on your real account. Here's the back-of-envelope math.
Your monthly Amazon ad spend
Likely waste / mo
30–40% of the typical Amazon ad budget, per SaaS PPC research.
Mirox Growth
Up to 50 ASINs across three marketplaces. Flat fee — no % of spend.
Break-even recovery
Recover 5.7% of your monthly waste and Growth pays for itself.

Industry waste range sourced from sellerqi.com and SaaS PPC research aggregated in our 2026 market study. Your number will differ — that's why Shadow Mode exists.
Recruiting ten Amazon sellers.
We're partnering with ten EU-based sellers spending €5K+/month for a 60-day founding-operator program. Two weeks of Shadow Mode, then Live from Day 15. Free for the program. 50% off year one, 25% off year two, locked for 24 months. Public Shadow Mode opens to everyone after the cohort wraps in Q3 2026.
Currently filling
Preview the AI. Then trust it.
Shadow Mode and the paid tiers all open to the public after the founding cohort wraps in Q3 2026. Until then, sellers spending €5K+/month can apply to the founding cohort.

Built, not assembled
A small team. A real platform.
Mirox is engineered by a Portugal-based team that ships its own infrastructure. No white-labeled vendor stack underneath. Every agent, every safety gate, every audit log — written here.
Every safety gate, every recovery path, every rate-limit edge case — tested before a bid leaves the system.
Kill switch, ROAS circuit breaker, spend cap, SP-API fault gate, optimistic locking, recovery floor, marketplace gates.
Strategist, Sentinel, Tactician, Semantic, Blackboard and 11 more — each with one job, all coordinated.
Direct integration with the official Amazon Ads API. No screen scraping, no third-party middleware.
Questions, answered
The five we hear most.
Three concrete differences. One — pricing: Pacvue starts at $500/mo with annual contracts, Perpetua at $695/mo, both gate visibility behind a sales call. Mirox publishes a €399 Growth tier and a free Shadow Mode tier with no card. Two — transparency: every Mirox decision exports as a trace showing the Bayesian inputs, the alternatives ruled out, and which of the seven safety gates were checked. The legacy tools surface a number, not a reason. Three — region: Mirox is built EU-native — DE/FR/IT/ES/UK/US/JP marketplaces, multilingual semantic, GDPR-compliant data residency. Most US tools bolt translation on top.
Two things stop that. Before any bid leaves the system, it passes through seven safety gates — kill switch, ROAS circuit breaker, daily spend cap, SP-API fault gate, optimistic locking, recovery floor, and per-marketplace thresholds. If a gate trips, the bid is suppressed and an audit entry explains why. Beyond that, Shadow Mode lets you watch the AI on your real account — free, indefinitely, before a single bid goes live. You see what the AI almost did, side-by-side with what your current setup actually did, and decide from data rather than promises.
Yes — that's the default. Mirox runs on EU infrastructure and ships with seven marketplaces enabled out of the box: Germany, France, Italy, Spain, United Kingdom, United States, Japan. ROAS targets, spend caps, and SP-API rate limits are tuned per marketplace, not blended. The semantic engine uses asymmetric multilingual embeddings, so German keywords get matched against German shopper intent — not translated through English first. Sellers running cross-marketplace copy without per-region tuning report a +28% ACoS hit. One €399 Growth plan covers up to three marketplaces.
Account access uses Amazon Ads OAuth — no credentials are stored on our side, and we can't place a bid until you flip Live Mode on. Campaign and sales data is stored on EU infrastructure under Mirox, LDA in Portugal. We don't sell, share, or train third-party models on tenant data. A signed DPA is available on request and required for the Growth and Scale tiers. Every API call to Amazon is logged with a trace ID you can pull on demand.
You export and you go. Every campaign change Mirox has made is exportable as a CSV with the original Amazon IDs intact, plus the decision trace that produced it. Disconnecting OAuth halts the system within seconds. There is no data hostage clause and no annual lock — the standard tiers are month-to-month. The founding cohort offer is a 24-month pricing lock, not a service lock; you can leave the lock and keep the platform on a regular tier.
