Autonomous A/B Testing

Improve yourImprovements that feel likewith magic*

Autonomous landing page optimization that writes copy, splits traffic, runs Bayesian statistics, and auto-promotes winners.

* Feels like magic. Behaves like magic. But it's 100% controllable, statistically confident, and fully transparent — actually just really smart tech.

Most A/B testing tools make you:
wait weeks, read p-values, approve every change.

We make improvements happen

autonomously.

Composite scoring (Conversion + Revenue + Engagement) replaces cheap vanity metrics. Bayesian statistics replace p-values. LLMs replace copywriters. You get an email when your MRR actually improves. That's it.

Behind the curtain

Engineered to be invisible.

Your visitors never notice. Your site never slows down. Everything happens at the edge, in real-time, with zero compromise.

0.3ms

Edge-first routing

Variants are assigned at the CDN edge via middleware — before your page even starts rendering. Zero layout shift. Zero flicker.

Full-Funnel Bayesian Engine

We score variants on Conversion (60%), Revenue (30%), and Engagement (10%), then run 10,000-sample Monte Carlo simulations. Avoids cheap clicks, optimizes for actual dollars.

Privacy-safe tracking

No cookies. No PII. Just a stable hash from timezone + screen size. Returning visitors get the same variant, always. GDPR by design.

auto-kill

Safety net built in

If a variant underperforms after 50 impressions with <15% confidence, it's killed automatically. Your champion always stays live.

Hot-swap, no deploy

Copy variants are injected at the edge — no code push, no CI/CD, no waiting. Promotions take effect in under 50ms worldwide.

30d window

Cross-session memory

Visitors who return days later see the same variant. Conversions are attributed within a 30-day window. No double-counting. Ever.

The Engine

Nightly autonomous cycle

01

Analyze

Bayesian confidence calculated for every variant using Monte Carlo Beta distribution sampling (10,000 samples).

02

Promote & Kill

≥95% confidence with 100+ impressions → auto-promote to champion. <15% confidence after 50 impressions → auto-kill.

03

Generate

LLM creates new challenger (subtle refinement) and explorer (bold experiment) variants from your brand guide.

04

Notify

Admin digest email with every action taken. You stay informed without being a bottleneck.
