Overview

About Lebesgue

Lebesgue pulls data from Shopify, WooCommerce, Meta, Google, TikTok, Amazon, Klaviyo and GA4 into one view covering store profit, customer lifetime value, competitor tracking and cross-store benchmarks. Its assistant, Henri, answers marketing questions against that data and against competitor ad signals, returning ranked recommendations rather than dashboards alone. First-party attribution with server-side tracking is sold as a separate Le Pixel tier, and an enrichment add-on feeds conversions back to Meta. Analytics plans are flat-priced regardless of store size.

Editorial verdict

Pros & cons of Lebesgue

high confidence

Good value for a mid-size DTC store that wants benchmarks and plain-language recommendations without hiring an agency. Once ad spend is large enough that attribution accuracy drives real decisions, Triple Whale and Northbeam are the stronger buy.

Pros

Benchmarks against other stores are a genuine differentiator over pure dashboard tools
Integration list covers Shopify, WooCommerce, Amazon, Klaviyo and the three big ad networks
Free plan lets you connect and look before paying

Cons

The AI assistant is capped at 10 questions a month on both Free and the $79 tier
First-party attribution through Le Pixel is a separate $749-a-month tier, about five times the Ultimate AI price
No public developer API found for exporting into a warehouse

Best for

Shopify stores between roughly $250K and $2M yearly revenue with no in-house analyst
Founders who want competitor and industry benchmarks alongside their own numbers
Teams running Meta, Google and TikTok ads who need one blended view

Not for

Marketplaces or non-ecommerce businesses, since integrations are store-centric
Stores that need multi-touch attribution on a small budget, since Le Pixel is priced as a premium tier

Watch out: Unlimited access to the Henri assistant only starts on the $149 Ultimate AI tier; the $79 plan is capped at 10 questions a month, which is easy to miss when comparing plans.
