Lebesgue, branded as Lebesgue: AI CMO, is a marketing analytics platform for eCommerce brands. The company describes it as an all-in-one tool that combines first-party attribution, customer lifetime value analysis, benchmarks and AI-driven insights, so store owners can make growth decisions from one place.
It is built mainly around Shopify stores but also supports platforms such as WooCommerce. The site says more than 10,000 eCommerce brands use it, though another homepage section cites 5,000, so the exact figure is unclear. It also lists an app rating of 4.9 across 150+ reviews.
Lebesgue connects to a store and its marketing accounts, including Shopify, Meta, Google, TikTok and email, along with product performance data. According to the site, this data passes through a proprietary analytics engine covering LTV models, attribution, product performance modeling, creative insights and competitor benchmarks.
On top of that engine sits Henri, an LLM-based assistant. Users ask questions such as why Meta ROAS dropped last week, and Henri returns explanations, root-cause analysis and step-by-step action plans. The site says the underlying predictive models are trained on thousands of eCommerce brands.
The platform includes an all-in-one dashboard, LTV and cohort analysis, product intelligence, stock inventory tracking and ecommerce benchmarks drawn from more than 20,000 brands. Competitor tracking covers ads, creative trends and email strategies, and a Creative Strategist gives feedback on ad creatives.
Le Pixel is a first-party tracking pixel with several attribution models, including game theory based options. Named AI agents handle budget split (Balancer), anomaly detection (Guardian), daily account audits (Auditor) and stockout monitoring (Sentry). Marketing Mix Modeling and AI visibility tracking for ChatGPT and AI search round out the list.
