The Post-Purchase Revenue Engine for Shopify DTC Brands

AI-powered SMS and voice orchestration that recovers checkout revenue leaks and lifts AOV and LTV β€” measured against a real control group, not vanity metrics.

Built for high-AOV Shopify brands that already invest in retention and want to capture what their existing flows leave behind.

The Hidden Problem: Revenue Is Leaking After Checkout

One-time buyers who never come back

Most DTC brands convert a customer once and hope email brings them back. Without a system built for the moments right after checkout, that customer's second order β€” and their subscription β€” never happens.

Broadcast marketing your best customers ignore

Generic newsletter blasts and templated flows get the same low single-digit response rate whether the recipient just spent $20 or $200. High-intent buyers deserve a channel built for their moment, not a queue.

The highest-intent moment on your funnel goes unused

The seconds right after a customer completes checkout are the highest-trust, highest-intent moment you will ever have with them β€” and for most brands, it's a static 'thank you' page that does nothing.

You can't tell what's actually working

Most retention tools report gross numbers and let you assume the credit. Without a real control group, you can't tell revenue your system created from revenue that would have happened anyway.

The Solution: A Multi-Channel Revenue Engine

SMS Cascade

A timed, branded SMS sequence reaches every customer first β€” at a fraction of the cost of a phone call β€” with a one-tap offer link hosted on our infrastructure.

AI Voice Concierge

When a customer signals real intent β€” a question, a stall, a tap-to-call β€” a real-time AI voice agent closes the conversation warmly and on-brand. Never a cold call, always an escalation the customer asked for.

Incrementality Engine

Every campaign runs against a live holdout control group, so the number we report is revenue the system actually caused β€” not revenue your existing flows would have captured anyway.

Compliance Built In

Consent capture, quiet hours, opt-out handling, and full call transcripts are enforced at the infrastructure level β€” so your brand equity is protected while the engine runs.

Every channel feeds one attribution system β€” so you see exactly what worked.

Real Numbers From a Live Deployment

These results come from an active, high-volume direct-to-consumer deployment running the same engine described above β€” on a low-price, low-loyalty impulse product, close to the hardest possible conditions for a retention system.

48.6%

Human click-through rate on outbound SMS

43.4%

Live answer rate on AI voice follow-ups

12–18%

Upsell acceptance on the order-confirmation concierge

664

Inbound callbacks handled by the same AI agent in one month

A brand with a higher order value and a loyal, repeat customer base is where this same engine's economics get materially stronger.

Frequently Asked Questions

Does this replace our Klaviyo or email marketing setup?

+

No. The Revenue Engine runs alongside your existing stack. It targets the specific moments β€” right after checkout, and the customers your broadcast flows don't reach one-to-one β€” that your current tools aren't built to catch.

How do you measure results without inflating the numbers?

+

Every campaign holds back a small, randomized control group that receives no contact. We report the difference in conversion between the group we engaged and the group we didn't β€” that gap is the revenue the system created, not revenue that would have happened anyway.

Will an AI voice agent hurt our brand experience?

+

The voice agent only engages when a customer asks for it β€” by replying to a text or tapping a call-me button β€” and it's configured to speak only from your approved product copy. It's built as a concierge escalation, not a cold outbound channel.

What does it take from our team to get started?

+

A short discovery call and a CSV export or a checkout-page integration β€” no engineering work required from your team to run the pilot.

How is pricing structured?

+

Founding partner pilots run for 90 days with the standard setup fee waived, a flat $3,500/month retainer, and infrastructure costs billed at cost β€” no markup during the pilot.
