Lebesgue
Lebesgue is an AI CMO for Shopify DTC brands — ask Henri a question, get attribution, LTV and competitor answers.
If you run a Shopify store and your Monday is spent reconciling Meta, Google, TikTok and Shopify in a spreadsheet, Lebesgue's $79/mo Analytics Ultimate tier buys you LTV, cohort analysis and competitor tracking (up to 7 rivals) for less than most attribution tools charge to start — and the free tier genuinely tracks profit and runs automated ad audits at $0. The ceiling arrives quickly: unlimited Henri, AI visibility tracking and ad copy/image generation sit behind the $149/mo Ultimate AI plan, and real first-party attribution is a separate Le Pixel line item. Triple Whale bundles more out of the box; Northbeam goes deeper on modeling. Lebesgue wins on entry price and the ask-a-question

Skip Lebesgue if you sell on WooCommerce, BigCommerce or Amazon rather than Shopify, or if you need to build and own custom attribution models from raw event-level data.
Henri is capped at 10 business questions per month on the $79/mo Analytics Ultimate tier — the moment you actually use the co-pilot daily, you're moving to the $149/mo Ultimate AI plan.
The free tier and $79/mo Analytics Ultimate sit well under what Northbeam or Triple Whale-class attribution stacks cost to start, which makes Lebesgue a low-risk first analytics subscription for a $250K–$2M Shopify brand. Past that, cost depends on Le Pixel: at $749/mo (or $1,499/mo in the other block on the same pricing page) attribution becomes a serious line item, and Enrichment on top pushes further. Buy Analytics first, add Le Pixel only when tracking accuracy is the bottleneck.

About Lebesgue
Lebesgue is an eCommerce analytics platform for Shopify DTC brands, with Henri — an LLM built on top of Lebesgue's own analytics engine — as the front door. You ask a plain-English question like "why did Meta ROAS drop last week?" or "what's actually driving profit right now?" and get a root-cause explanation plus suggested next steps, drawn from attribution, LTV, product performance, creative analytics, email behavior and competitor intelligence rather than one ad channel. Ten named AI agents carry the recurring work: Balancer for cross-channel budget split, Guardian for anomaly detection, Spotlight for high-potential products, Sentinel for competitor ad monitoring, Echo for rivals' email and discount tactics, Pulse for market trends, Prophet for GAM marketing-mix models, Sentry for stockout risk, Auditor for daily Meta/Google/TikTok account audits and Strategist for creative feedback. Le Pixel is the separate first-party attribution product, with AI cross-device visitor matching, unlimited data retention and server-side tracking, plus Meta Conversions API once you add Enrichment. The free tier is real — order history, profit tracking, ad analytics and automated audits at $0 — and Analytics pricing is fixed regardless of store size. The $79/mo Ultimate plan adds LTV, cohort analysis, competitor tracking (up to 7) and 10 Henri questions a month; the $149/mo Ultimate AI plan unlocks unlimited Henri, AI visibility tracking for GEO and AEO, blog generation, ad copy suggestions and AI image creation. Benchmarks run against a pool the company cites as 20,000+ brands. It is Shopify-first, so multi-platform sellers are mostly out of scope.
Behind the Verdict
Lebesgue's pitch is narrower and more honest than most analytics vendors': it is a Shopify analytics engine with a conversational front end, not a modelling lab. The architecture matters when you evaluate it. Henri is explicitly "an LLM built on top of Lebesgue's analytics engine" — the answers draw on Lebesgue's own LTV models, attribution, product performance modelling and competitor benchmarks, which is why it can explain a ROAS drop rather than just restate it. That is a meaningfully different product from a chatbot pointed at a dashboard. Strengths. The free tier is unusually complete: full order history, COGS and profit tracking, advertising analytics across Meta, Google, TikTok, Pinterest, Microsoft and Klaviyo, and automated Meta/Google/TikTok audits, all at $0/mo. Analytics pricing is fixed regardless of store size, which matters if you are growing fast and don't want a bill indexed to GMV. The named agents map to real recurring jobs — Auditor runs daily account checks, Sentry watches inventory so you don't keep scaling spend into a stocked-out SKU, Sentinel and Echo track competitor ads and email tactics. The vendor also publishes geo-holdout work measuring how much revenue Meta Ads actually drove using first-party attribution rather than platform-reported conversions, which is the right instinct for a company selling measurement. Weaknesses. Henri is throttled hard on the $79/mo tier at 10 business questions per month; unlimited analysis, Deep Mode and AI content generation require the $149/mo Ultimate AI plan, so the tier most buyers pick is a trial of the co-pilot rather than the co-pilot itself. Le Pixel is not bundled: the pricing page shows Attribution at $749/mo in one block and $1,499/mo in another, and Enrichment at $149/mo versus $1,649/mo — you must confirm which figure applies to your store before committing, and Enrichment requires Advanced or Ultimate Analytics on top. Competitor tracking caps at 3 rivals on the free tier and 7 higher up. The storefront integration is Shopify-centred, so WooCommerce, BigCommerce and Amazon sellers are out of scope, and agencies wanting white-label client reporting won't find it here. Where it fits. DTC brands roughly $250K to $10M+ that want attribution, LTV and competitor data in one place without hiring an analyst, and growth leads who would rather ask a question than build a pivot table. Where it doesn't: teams that want to query raw event data and build their own attribution models, or brands whose measurement needs justify Northbeam-level modelling depth.

Real-world workflow fit
Concrete scenarios for the personas Lebesgue actually fits — and what changes day-one when you adopt it.
Meta ROAS looks fine in Ads Manager but bank deposits don't match. You connect Shopify and the ad channels on the free tier, see profit by channel, then ask Henri what's actually driving profit — pulling attribution, LTV and product performance into one answer.
Outcome: You find one channel quietly buying first-time customers at a loss and reallocate before the next month's spend, without buying a dashboard you'd have to learn.
Every Monday you reconcile Meta, Google, TikTok, Pinterest, Microsoft and Klaviyo against Shopify. On Analytics Ultimate you get automated Meta, Google and TikTok audits, LTV and cohort analysis, and tracking of up to 7 competitors' Meta ads and email discount patterns.
Outcome: Monday reconciliation collapses into a review of flagged anomalies from Auditor and Guardian, and you spend the freed time on the two or three creative and budget calls Henri surfaces.
Post-cookie browser attribution no longer reconciles with platform-reported conversions. You add Le Pixel Attribution and Enrichment for first-party pixel tracking, server-side tracking and Meta Conversions API, with AI cross-device visitor matching and channel/campaign/ad-level insights.
Outcome: You get a first-party view of which campaigns actually drive revenue, and can validate it against the vendor's geo-holdout approach to incrementality rather than trusting platform-reported conversions.
Use Cases
- Ask Henri why Meta ROAS dropped last week and get a root-cause explanation instead of a dashboard to dig through.
- Identify your highest-LTV customer cohorts and target lookalikes from LTV and cohort analysis.
- Track up to 7 competitors' Meta ads, creative trends and email discount patterns from one screen.
- Run first-party attribution through Le Pixel to measure true channel contribution without relying on browser cookies.
- Watch inventory with Sentry so you do not keep scaling ad spend into an out-of-stock SKU.
- Get daily automated audits for Meta, Google and TikTok accounts to catch errors and anomalies early.
- Compare CAC, LTV, ROAS and MER against ecommerce benchmarks from a pool the vendor cites as 20,000+ brands.
- Generate ad copy suggestions, AI images and blog posts from the Ultimate AI tier.
Models Under the Hood
as of 2026-10-18
Limitations
- The scrape documents Shopify as the central storefront integration, so multi-platform sellers are likely out of scope.
- Le Pixel attribution and Enrichment are sold as add-ons on top of Analytics Advanced or Ultimate, not bundled, and the pricing page presents two different price blocks ($749/mo Attribution and $149/mo Enrichment in one layout; $1,499/mo and $1,649/mo in another), so confirm the applicable figure before you commit.
- Henri AI access is capped at 10 business questions per month on the $79/mo Analytics Ultimate tier; unlimited analysis, Deep Mode, AI visibility tracking and AI content generation require the $149/mo Ultimate AI tier.
- Competitor tracking is limited to 3 competitors on the free tier and 7 on paid tiers.
- The docs and developer pages were not reached in this run, so integration depth and API behaviour beyond the listed ad and email platforms are unverified.

Where the pricing makes sense
The company stage and team size where Lebesgue's pricing actually pencils out — and where peers do it cheaper.
The free tier and $79/mo Analytics Ultimate sit well under what Northbeam or Triple Whale-class attribution stacks cost to start, which makes Lebesgue a low-risk first analytics subscription for a $250K–$2M Shopify brand. Past that, cost depends on Le Pixel: at $749/mo (or $1,499/mo in the other block on the same pricing page) attribution becomes a serious line item, and Enrichment on top pushes further. Buy Analytics first, add Le Pixel only when tracking accuracy is the bottleneck.
Setup time & first value
How long it actually takes to get something useful out of Lebesgue — broken out by persona, not the marketing-page minute.
Connecting Shopify and your ad channels on the free tier is a same-day job — most of the time goes into waiting on historical data to backfill, not configuration. Expect useful profit and channel numbers within the first day and meaningfully predictive LTV once you have a few months of order history. Le Pixel with server-side tracking and CAPI is a separate implementation that will need a
Switching to or from Lebesgue
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a spreadsheet stack: connect Shopify and the ad channels on the free tier first, confirm profit and COGS figures reconcile, then move to Analytics Ultimate for LTV and competitor tracking.
- →From Triple Whale: keep it running for a month alongside Lebesgue, compare channel-level profit and MER on the same window before cancelling.
- →From Northbeam: export historical channel-level numbers so you can sanity-check Lebesgue's attribution output against your prior baseline before switching budgets.
- →From Google Analytics: use Lebesgue's Shopify order history as the revenue source of truth and treat GA as a traffic diagnostic rather than the revenue ledger.
- ↗To Triple Whale: export order, COGS and channel spend data before you cancel, since Triple Whale rebuilds attribution from its own pixel history.
- ↗To Northbeam: expect to re-implement tracking, as Northbeam's modelling runs on its own event pipeline rather than imported attribution output.

Featured Head-to-Head Comparisons
Lebesgue vs Chili Piper
Chili Piper and Lebesgue serve completely different markets: Chili Piper is for B2B enterprise teams that need to instantly book meetings from inbound web traffic, while Lebesgue is built exclusively for Shopify merchants needing AI-driven attribution and marketing intelligence. If you're a B2B company with Salesforce, Chili Piper is the obvious choice; if you run a Shopify store, Lebesgue's free tier and specialized AI agents make it a no-brainer.
Lebesgue vs Screenplayiq
These are not competitors — the pairing is a categorization error. ScreenplayIQ is a per-analysis screenplay evaluation tool for screenwriters and producers; Lebesgue is a Shopify-native marketing intelligence platform for DTC brands scaling past $250K. Nobody holds both on a shortlist. Screenwriters comparing it should weigh it against AI script-coverage services; Shopify founders comparing it should weigh it against attribution and marketing-analytics tools.
