Lebesgue vs B12

Lebesgue pulls Shopify or WooCommerce revenue, Meta and Google ad spend, and email performance into one e-commerce analytics workspace with Henri AI on top. It rolls attribution through Le Pixel, lifetime value modeling, competitor tracking, and named AI agents into a single dashboard instead of scattered spreadsheets. The Henri assistant lets you ask business questions in plain English and get answers grounded in your store data instead of generic chatbot guesses. Brands use it when platform dashboards stop explaining why revenue or ROAS shifted.

Unlike standalone attribution tools such as Triple Whale or Polar Analytics, Lebesgue bundles first-party pixel tracking (Le Pixel), marketing mix modeling, and named AI agents like Balancer and Sentinel in the same subscription. Its competitor intelligence pulls live ad creative and email campaigns from rival brands, which most analytics suites treat as an afterthought. The trade-off is scope: Le Pixel attribution tiers sit on top of the $79 or $149 analytics plans rather than selling as a single-purpose pixel product.

Shopify and WooCommerce operators who spend across paid social and search use Lebesgue to audit ad accounts, benchmark against 20,000+ stores, and decide where the next dollar goes. Growth teams lean on LTV and product intelligence modules when retention matters as much as acquisition. Merchants who want a conversational layer on top of verified metrics reach for Henri on the Ultimate AI plan with unlimited monthly questions.

B12 turns a short text prompt into a live website, online store, or lightweight web app in about two minutes. Its AI builder drafts mobile-responsive pages, then you refine layout, copy, and features through chat or a visual editor without touching code.

Squarespace and Wix ship template libraries you customize manually. B12 bundles site generation with commerce backends, client intake forms, invoicing, contracts, email marketing, and an expert marketplace when you want humans involved. That makes it closer to an all-in-one stack for service businesses than a pure site builder.

Freelancers, coaches, and small firms use it to launch on a free b12sites.com subdomain or move to a custom domain on paid plans. B12 says more than 4 million sites have been created on the platform, with Website at $49 per month (200 AI credits) and Website + Client Engagement at $78 per month (300 credits), both offered at $1 per month for the first three months for new users.
