The underlying bug, A/B testing optimizes what works; it doesn't surface a checkout that crashes or a pixel that lies
Mimetic vs Sherpa
You can't A/B test your way past a broken checkout
Sherpa studies your visitors and runs A/B tests to find a winning variant over about 30 days. But if your checkout crashes on iOS, your pixel is misfiring, or a consent banner covers the Buy button, no variant wins. Mimetic finds the bug now, and ships the fix.

The gap
What Sherpa misses.
An AI agent that studies visitor behavior, designs on-brand variants, and runs A/B tests to lift your primary conversion metric, typically over a 30-day window.
Tracking verification, if your analytics are wrong, every test result is unreliable. Mimetic checks this first
Cross-browser and cross-device defects, the iOS-only checkout error that silently kills conversions
Speed and technical SEO, slow pages and crawl issues that suppress traffic before any test runs
A real code fix, Sherpa ships client-side variants via a snippet; Mimetic opens a reviewable GitHub PR
Shopify platform depth, app conflicts, theme issues, checkout extensibility

FAQ
Frequently asked questions.
How does Mimetic compare to Sherpa?
Sherpa is an AI agent that designs and runs A/B tests to lift your conversion rate over about 30 days. Mimetic is a diagnostic: it scans your store across browsers and devices, finds the technical and conversion bugs that are losing you customers right now, and ships fixes as reviewable PRs. Testing finds a better variant; Mimetic finds what's broken.
Can I use both Sherpa and Mimetic?
Yes, and in that order. Run Mimetic first to fix the leaks and verify your conversion tracking is accurate, otherwise any A/B test you run on top of broken tracking will give you unreliable results. Once the foundation is sound, A/B testing tools like Sherpa can optimize on top of it.
Why does the 30-day testing window matter?
A/B tests need traffic and time to reach statistical significance, often around 30 days per test. If a checkout bug or broken pixel is costing you sales today, you don't want to wait a month to start fixing it. Mimetic surfaces those issues in minutes so you can recover revenue immediately.
