Switch from Lebesgue to Causality Engine
Lebesgue uses competitive benchmarking + marketing audit. Causality Engine uses causal inference on your GA4 export. There is nothing to migrate: the first read takes 1 to 2 minutes, and you can run both side by side.
€99 once, excl. VAT. Keep Lebesgue running while you compare.
What Lebesgue's terms say, before you leave.
Short answer: there is nothing to migrate. Keep Lebesgue running, upload your GA4 export, and compare the two for a month. Cancel only if the comparison says so, on the terms below.

Lebesgue and Causality Engine, fact by fact
Competitor pricing is each vendor's publicly listed pricing as read on the date shown, and it changes without notice: verify on the vendor's own site before relying on it. Vendors without a public price are marked as such. Comparisons set Causality Engine's one-time €99 analysis against subscription models.
How to switch, in five steps.
No cancellation required yet
Keep Lebesgue running (its terms: monthly or annual). Causality Engine reads your GA4 CSV export, so nothing conflicts and no data moves between the two.
Upload your GA4 CSV (no integration required)
Export 12 months or more of GA4 data and upload it. Longer reads better. No OAuth, no pixel, no code, no DNS changes. Shopify native is on the roadmap.
Run your first analysis
What each channel caused, next to last-click, with a data-health score on each, 1 to 2 minutes after the upload. Compare it with what Lebesgue was telling you.
Evaluate side by side
Run both for a month and compare them channel by channel. Where they disagree is where a budget decision is at stake.
Cancel Lebesgue when ready
Only if the side-by-side says you should. Nothing in Causality Engine depends on Lebesgue being gone.
What to weigh before you leave Lebesgue
Lebesgue uses competitive benchmarking + marketing audit and is best for Shopify brands wanting competitive insights and ad auditing. Where it differs from a causal read:
- Benchmarking/audit tool, not true attribution
- Reports credit and behaviour, not a counterfactual estimate of what a channel caused
- No causal inference methodology
- Competitive data is directional not precise

Yes. Causality Engine installs nothing on your site. It reads the GA4 export you already have, so it runs on top of any tool here without touching its setup. The one condition: GA4 runs on your store too.
