Lengow: cost, fit and limits
Lengow is a product feed and marketplace software company, registered as a SAS with an office in Luxembourg, that manages product feeds for marketplaces and advertising channels and sells competitive price intelligence on competitors and resellers.
What to know first
Lengow publishes no prices. Its pricing page leads to a demo request and shows no plan breakdown. The product pages describe feed management and distribution, competitive price intelligence that tracks competitor and reseller prices, reseller network intelligence, Local Inventory Ads support and an AI Shopping readiness page. The legal notice gives a Luxembourg registered office, and no trial is mentioned.

Who Lengow is best for
Retailers that track competitor prices
Competitive price intelligence follows competitor and reseller prices, so a merchant can see where its listings sit before it changes any prices inside the feed.
Brands policing resellers
Reseller network intelligence is listed, which suits manufacturers who want to see who sells their products and at what price across marketplaces and shop sites.
Stores with physical locations
Local Inventory Ads support is listed, which fits retailers that want store stock to appear in Google shopping results next to their online catalog.
Lengow plans and pricing

What Lengow does
- Feed management and distribution
- Catalogs are shaped for marketplaces and advertising channels, which is the core of the product and the part that most buyers come to compare with other feed tools.
- Competitive price intelligence
- Competitor and reseller prices are tracked, which supports pricing decisions that sit outside the feed itself and need a separate contract in the vendor's description.
- Reseller network intelligence
- Brands get visibility into resellers, a feature aimed at manufacturers more than at single-shop merchants who only sell their own stock through their own channels.
- Local Inventory Ads
- Support for local inventory listings connects store stock to Google surfaces for shops with physical locations, which online-only feed tools often leave out of their feature lists.
- AI Shopping readiness
- A dedicated page covers preparing catalogs for agentic commerce. The AI app pages were not opened, so their scope and data handling are unchecked in this review.
How Lengow handles your data
The customer and supplier privacy policy exists and its link was recorded, but it was not read in full. The pages opened did not state a hosting region, a retention period, whether customer data trains AI models, or any certification. The legal notice identifies the company as a SAS with a registered office in Luxembourg. For these points the vendor's policy was not checked, so ask the sales team directly.
Where Lengow falls short in practice
- No prices on the pricing page. A buyer must book a demo to learn any cost, which slows comparison with vendors that print their tiers and offer a trial, and delays any budget approval inside the buying company.
- Price intelligence is a separate solution. Competitor tracking is not part of feed management, so a merchant who wants both has to buy both and should ask whether they share data.
- AI apps unchecked. The AI app pages were not opened, so what they do and how they handle data is unknown, and a buyer should ask for a demo of each one.

Alternatives to Lengow
Lengow: common questions
How much does Lengow cost?
Lengow lists no prices. The pricing page offers a demo and gives no plan breakdown. Expect a quote based on your catalog and channels. Prepare a channel list and SKU count so the demo covers your real use and you can compare offers from other quote-only vendors.
Where is Lengow based?
The legal notice gives a registered office in Luxembourg and describes the company as a SAS. The candidate list assumed France, which the notice did not confirm. If country of establishment matters for your procurement review, read the legal notice yourself.
Does Lengow offer price monitoring?
Yes. Competitive price intelligence tracks competitor and reseller prices, and it is described as a separate solution from feed management. You may need two contracts or a bundled quote. Ask whether competitor price data can flow back into your feed rules automatically or only through manual exports.
Does Lengow support AI shopping channels?
The homepage names AI Shopping readiness and AI apps, and a page covers readiness for agentic commerce. The AI app pages were not opened, so we cannot say which channels or models are involved. Ask for a list of supported AI surfaces and test one.
Can I try Lengow without talking to sales?
The pricing page offers a demo and shows no self-serve plan or trial. That makes Lengow slower to evaluate than tools with a free trial. Request the demo with your real catalog sample, not the vendor's, so you see how your data behaves.
