What Zactr does
Zactr connects marketplace observations into a practical intelligence layer for Amazon commerce. It tracks ASINs, sellers, categories, bestsellers, offers, Buy Box ownership, promotions, discounts, demand keywords and competitive movement across supported marketplaces.
The product is built around decisions that affect revenue and margin: which products to defend, which products to test, which categories are becoming more attractive, where demand is emerging, where competitors are changing behaviour, and where pricing or fulfilment pressure is likely to matter.
Zactr currently supports Germany and is expanding coverage across France, Italy, Spain and India.
ASIN and seller intelligence
For a verified seller, Zactr captures the storefront ASIN list where available, enriches product evidence, tracks Buy Box position, compares observed offers, separates FBA and FBM pressure, highlights coupons and deal effects, and turns the evidence into a daily action queue.
ASIN tracking lets a team follow important products over time: owned products, lost Buy Box products, sourcing candidates, competitor products, high-review products, bestseller entrants and products with changing promotion pressure.
Seller tracking shows portfolio shape, observed ASINs, storefront coverage, contact evidence, Buy Box overlap, competitor pressure and seller-level movement. For operators and investors, this creates a richer view of a seller than a simple storefront list.
Category, demand and competitive intelligence
Category intelligence follows marketplace structure, product count movement, seller and brand participation, offer depth, Amazon presence, FBA share, coupon penetration, price stability and category opportunity scores. The goal is to identify where a category is becoming more attractive, more crowded, more volatile or more exposed to Amazon pressure.
Bestseller intelligence tracks entrants, exits, rank velocity, persistence and category-level movement. It helps separate temporary promotion spikes from more durable visibility changes.
Demand intelligence combines observed marketplace movement with keyword and search-demand context. Zactr is designed to surface new demand areas, emerging keywords, new category openings and product groups where sellers may want to validate listing, advertising, sourcing or pricing tests.
Competitive intelligence connects sellers, ASINs, offers, Buy Box holders, fulfilment method, deal pressure and category position so teams can see who is gaining visibility and why it may matter commercially.
Reports, dashboards and API
Zactr provides weekly market reports, private seller reports, a seller dashboard, ASIN watchlists, category and bestseller intelligence, Buy Box analysis, Product Finder workflows, exports and API access.
Starter API access is focused on one verified seller and that seller's own or tracked products. Pro API access opens the wider marketplace graph: products, sellers, categories, bestsellers, deals, demand objects, AI scores, Buy Box holders, category ownership and exports.
The AI predictive layer converts product, seller, offer, category, bestseller, deal and demand signals into prioritisation fields such as opportunity score, Buy Box risk, offer pressure, demand score, promotion pressure, confidence and recommended action.
Who uses it
Sellers use Zactr to improve revenue and margin by focusing attention on the ASINs and categories where action is most likely to matter.
Brands and agencies use Zactr to monitor competitive activity, Buy Box movement, category pressure, promotion intensity and portfolio risk.
Aggregators, acquirers and investors use Zactr as a deeper marketplace data layer for seller research, category mapping, competitive benchmarking, diligence, portfolio monitoring and further analysis.
