Lengow is a solid European reference for marketplace syndication and market intelligence (NetRivals, NetMonitor). Where Lengow excels on that digital-shelf scope, Dataïads focuses on catalog media performance: semantic and multimodal feed enrichment, Catalog Ads and Video Ads creatives, post-click and A/B proof. Two different scopes, then: one centered on marketplace distribution and competitive monitoring, the other on end-to-end performance, from pre-click to post-click, across media channels.
Your priority is digital shelf coverage: selling on dozens of marketplaces across 45 countries, syncing orders and stock, monitoring competitor prices and controlling resellers. On those fronts, Lengow is a solid European reference — and that is not Dataïads' ground.
You manage a large, important or complex catalog (500+ SKUs) and need a product data activation platform to maximize performance marketing ROAS, AI visibility (AEO / GEO) and agentic commerce, full-funnel from pre-click to post-click. Built for marketing teams, marketing directors and ecommerce digital leaders who own performance.
Already adopted by retailers and brands that treat catalog performance marketing as a primary growth lever. Google-certified Generative AI for Marketing 2026 referent: our teams run it managed, your agency runs it, or you go self-service. See our clients
You are already a Lengow client with real media budget. Keep it for marketplaces and market intelligence, connect Feed Enrich upstream or downstream for data quality and add post-click. Dataïads installs as a secondary feed, your source stays intact, and impact is measured in A/B tests before any commitment.

Lengow's AI Studio maps products to the right taxonomy, localizes content in 12 languages, and makes images compliant with each channel's specs — three solid building blocks aimed at platform acceptance. Dataïads works a different layer: getting chosen by the buyer and by the algorithm. Our multimodal AI creates data absent from the feed. Dataïads centralizes and enriches catalog data through multi-source connectors: scraper, BigQuery, CSV, Google Ads, Meta, Google Merchant Center. Channel-calibrated titles, generated attributes, product benefits, Q&A pairs for AEO, enriched visuals. A compliant listing enters the race; an enriched listing wins it.

Lengow covers the upstream solidly: the feed goes out to 1,400 ad channels and 90 marketplaces. Beyond the click, the media journey continues — and that is where margin is won. Dataïads extends the chain: enriched feed, Meta catalog ads, Google Shopping, then post-click Smart Landing Page, Stories Landing Page for Meta immersion, and Smart GEO Page for intent queries handled by AI assistants. Six journey touchpoints, handled with the same operational standard, with no IT dependency and no impact on your CMS.

Post-click landing pages for Shopping and Meta traffic: the clicked product, a relevant catalog and AI recommendations from the first scroll. No CMS, no IT, A/B tested.
Outside Lengow's scope
The same SKU in native catalog formats (feed, Stories, carousel), ready for media activation.
Shopping visuals and attributes optimized for the SERP: strong packshot, title, price, free shipping.
On Meta, the experience is full-screen and vertical. The Stories Landing Page keeps that immersion through purchase, generated from your feed, no IT.
Outside Lengow's scope
A listing page driven by the enriched feed: filters, grid and merchandising to capture category intent.
Outside Lengow's scope
Full marketplace PDP: gallery, buy box, bullets and cross-sell. Catalog ready to convert off-site.
GEO pages cited by AI. One prompt, one page built for intent: clean URL, structured content, JSON-LD, generated from your product feed, no IT.
Outside Lengow's scopeFrom the feed to the Smart GEO Page, Dataïads activates every media surface. Lengow focuses its scope on marketplace distribution and market intelligence.
AI Image Compliance crops, resizes and cleans your visuals so they pass each channel's checks — a real need, and Dataïads does it too. Where Lengow stops at image compliance, Smart Creative builds the creative: thousands of Catalog Ads and Video Ads from your feed, in PNG and MP4, with AI-generated lifestyle scenes and brand fidelity in pixel-perfect QA. Two different jobs: fitting a visual to channel specs, or producing the asset variety Meta and Google reward.
Lengow orchestrates the feed and distribution. No catalog creative engine, no post-click activation, no asset studio connected to the feed. Dataïads closes the gap: rigorous semantic enrichment (titles, attributes), and on top multimodal image, synchronized with Feed Enrich. That data powers activations across the customer journey and conversion funnel, from the same catalog.
Multimodal catalog enrichment (text + visuals) in the feed.
Automation of Catalog Ads & Video Ads enriched with feed data.
Shopping Ads landing pages, Stories LP, Smart GEO Page.
Multimodal assets for every ecommerce content need. Multi-model / multimodal studio branched on the feed.
Examples produced by Smart Creative from an enriched feed.

Lengow is strong on marketplace syndication and market intelligence in Europe. Where Lengow covers that digital-shelf scope, Dataïads works catalog media performance, from feed to post-click. Two scopes: distribution & monitoring on one side, full-funnel performance on the other.
Dataïads is compliant with the European AI Act. Read our guide to Article 50
Both transform a feed with conditional rules, enrich data with AI, ingest external sources into a unified catalog, make visuals compliant channel by channel, handle multilingual content and sync Google and Meta in real time. Both publish quantified client results. On paper, boxes check on both sides. The gap sits elsewhere: what the AI is trying to achieve, how far the chain goes after the click, and how created value is proven.
Lengow built a suite to cover the digital shelf: sell everywhere, at the right price, with a protected brand. Four products, four different problems — and on that ground, Lengow is strong. Dataïads built a performance platform around AI, focused on one problem: making your product data sell, from the feed to AI shopping agents. One goes wide; the other digs into media performance. To understand why your feed now decides your visibility in AI, read our analysis on ChatGPT and Merchant Center. ChatGPT and Merchant Center.
Lengow's AI Studio brings together three applications: category mapping, content localization, image compliance. The thread is clear and legitimate: reduce rejections and speed up go-live. Feed Enrich pursues a different goal: generating selling power. Titles calibrated for each channel's algorithms, attributes and benefits created from your site via dataiadsBot, Q&A pairs designed for AEO, visuals enriched in real time with your prices and stock. A compliant listing enters the race; an enriched listing wins it. For how it works, see the Feed Enrich page and the reference article. Feed Enrich page · Feed Enrich reference article .
Reformatting an image to a channel's specs and generating an ad are two different jobs. Lengow does the first, very well. Smart Creative does the second with a studio as intuitive as Canva, connected to the feed: multi-format Catalog Ads and Video Ads, at catalog scale, automated production, dynamic title, price and promo overlays, brand guidelines respected. Meta and Google reward asset variety; that variety is built from the feed.
Lengow's scope stops at the click — consistent with its digital-shelf axis. Yet conversion, and already visibility in AI assistants, is also won after the click. Smart Landing Page, Stories Landing Page and Smart GEO Page extend the enriched catalog into the post-click experience, without touching your CMS or SEO.

No. If you sell on marketplaces or use NetRivals and NetMonitor, keep Lengow — those are solid capabilities we do not have. If your media focuses on Google and Meta, Dataïads publishes directly via the Merchant API and Meta API: in that case, an extra distribution tool is not needed for that scope.
Their results are real and impressive; we do not dispute that. The difference is attribution method: we measure in 50/50 A/B clusters, half the catalog enriched, half as control, on your real KPIs. That isolates precisely what enrichment delivered, independent of seasonality or budget changes.
No. NetRivals and NetMonitor address price monitoring and brand protection needs outside our scope. We work on product data performance and conversion, from the feed through to AI agents.
Compliant does not mean performant. That is exactly what the free audit reveals: our Feed Score analyzes 40 data points and quantifies the upside on your current budget. If your feed is truly optimal, you leave with proof. Otherwise, with a plan.
30 days for a standard rollout, 15 days on fast-track. Your source feed stays intact: we operate as a supplemental feed, with no IT dependency.
That is our field. An enriched, structured feed is the condition to be understood and recommended by AI agents, and Smart GEO Page generates the intent pages those assistants cite. Dataïads holds the first Google GenAI for Marketing certification and publishes the Agentic Commerce Index.
