Retention engine that just works
Connect Shopify/Woo + your ESP (Klaviyo, Mailchimp, SendGrid). We deploy and optimize Cart Abandonment, Browse Abandonment, and Winback. Measured by incremental lift, not vanity attribution.
Set it up once. We handle the rest.
How It Works
Get up and running in three simple steps. We handle the complexity.
Connect store + ESP
Link your Shopify or WooCommerce store and your existing ESP (Klaviyo, Mailchimp, or SendGrid).
Set offer guardrails
Define max discount, free shipping rules, free product eligibility, and category exclusions.
Autopilot
We test timing, subject lines, copy, and offer policy to continuously increase incremental revenue + LTV.
The Revenue Science Approach
We combine rigorous data science with AI personalization to prove what actually drives revenue.
Data Analysis
Scientific Customer Understanding
We analyze your customer data using RFM segmentation and behavioral cohort analysis to identify hidden revenue opportunities.
AI Personalization
Brand-Aware Content Generation
Our AI learns your brand voice to generate personalized emails that sound exactly like you, at scale.
"Hey [Name], noticed you left something behind..."
Causal Measurement
Rigorous Impact Quantification
We use randomized control trials to prove exactly how much revenue we generate, separating signal from noise.
What We Manage
Three proven flows. Fully managed. Continuously optimized.
Cart Abandonment
Recovers add-to-cart and abandoned checkout sessions
Timing, subject line, offer
Incremental lift via holdout groups
Browse Abandonment
Re-engages product page viewers who didn't add to cart
Timing, subject line, offer
Incremental lift via holdout groups
Winback
Reactivates lapsed customers who haven't purchased recently
Timing, subject line, offer
Incremental lift via holdout groups
Prove the Lift. Eliminate the Guesswork.
Most platforms take credit for revenue that would have happened anyway. We don't. We run continuous holdout groups to measure the true incremental lift of our campaigns.
Bring Your Own Mail Provider (ESP)
No migration required.
Offer Guardrails
You stay in control. Set the boundaries, and we'll optimize within them.

We Win When You Win
Our incentives are completely aligned with yours. We only make money when you make more money.
How Performance Pricing Works
Pay Fixed Monthly Fee
Your base subscription is billed monthly to cover core platform costs and infrastructure.
We Measure Incremental Revenue
Using randomized control trials, we measure revenue from treatment vs. control groups to calculate your true incremental lift.
Pay Performance Fee Quarterly
Every quarter, we calculate the incremental revenue and charge the performance fee percentage only on that proven lift.
You Only Pay for Proven Results
The performance fee is charged only on revenue you would not have made without our platform. No incremental revenue = no performance fee.
You set the retainer to performance fee ratio
Monthly Retainer
$1,750
/month
Performance Fee
15%
of incremental revenue
You only pay performance fees when lift is verified.
