When EU sellers reach for Niche Founder
- Discover products dominating amazon.de but underserved on amazon.fr — typical 50-200x BSR gaps surface in cache
- Validate a category before sourcing: Founder Score 70+ flags a strong opportunity, sub-50 flags weak
- Get a launch thesis in plain English: which marketplace to enter first, what risks to expect, what to do this week
- Cross-check a Helium 10 finding against EU-specific data (VAT, EUR pricing, marketplace-by-marketplace BSR)
How it works
- Pick a Keepa root category (Sports & Outdoors, Kitchen & Home, Health & Personal Care — 12 catalog categories supported)
- Pick a primary marketplace (DE, FR, IT, ES, or UK). The engine fans out to the other 4 EU markets to find gaps
- AgentXray pulls bestsellers + cross-marketplace data from Keepa (5,000-token budget per analysis), then runs the candidate set through scoring + AI thesis generation
- You receive 5 candidates with Founder Scores 0-100, full marketplace data tables, and a written thesis per candidate. Save promising ones to Watchlist

Inside Niche Founder


Frequently asked questions
- How is Niche Founder different from Helium 10 Black Box or Jungle Scout Niche Hunter?
- Both rivals score niches inside one marketplace at a time. Niche Founder is built for cross-marketplace gaps — products that dominate amazon.de but are underserved on amazon.fr/it/es/co.uk. The engine returns the gap multiple (e.g. 184x BSR difference) and an AI thesis explaining which marketplace to enter first. Both rivals also bill in USD; AgentXray bills in EUR.
- How accurate is the Founder Score?
- Founder Score 0-100 combines five sub-scores (gap, demand, competition, price, supplier) using Keepa-sourced BSR and price history. Scores 70+ have been validated against post-launch performance for our beta cohort; scores below 50 typically have a structural barrier (saturation, thin margin, or supplier difficulty). The score is a relative ranking inside your scan, not an absolute forecast.
- Which categories and marketplaces are covered?
- 12 Keepa root categories: Sports & Outdoors, Kitchen & Home, Health & Personal Care, Beauty, Home Improvement, Pet Supplies, Toys & Games, Office Products, Garden, Baby, Automotive, and Industrial. Primary marketplace can be DE, FR, IT, ES, or UK; the engine cross-references against the other 4 EU markets automatically.
- How long does an analysis take and can I run multiple in a row?
- A fresh analysis takes 30-90 seconds depending on Keepa load (5,000-token budget per analysis). Cached results return in under 2 seconds. Each tier has a daily cap: Starter 1/day, Pro 5/day, Founder 10/day. Free tier returns HTTP 403.
- Is the data live or cached?
- AgentXray caches results for 7 days per (category, primary marketplace) pair. With 12 categories × 5 markets = 60 unique keys, day-1 fills the cache and subsequent days hit ~95% from cache. Watchlist semantics are unchanged: each user keeps their own snapshot history regardless of cache state.
