The Diagnostic proves it. The score runs it. The playbooks compound it.
Tacet is one engine sold as three products: the free Diagnostic on your own data, the Forward CLV subscription that delivers the scores to Klaviyo, and the Playbooks the model personalizes to your customer base.
One engine, three products.
The Diagnostic proves the engine on your data. Forward CLV runs it daily. Playbooks compound it. Each product earns the next; nothing is sold on a promise the previous one didn't already prove.

One read-only Shopify connection is the whole Diagnostic integration. The subscription adds a Klaviyo sign-in. No engineering time on your side, at any point.
This is the Diagnostic. Yours arrives on your data.
The Diagnostic returns a read like this: customer tiers, value concentration and named leak sources.
A forward CLV score for every customer
Not what a customer has spent, but what they will contribute over the next 12 months, in dollars, after product costs and expected returns. Scored the morning after their first order.
Where your value actually concentrates
Your book ranked by forward value, so you can see the thin top tier worth a multiple of the rest, and fund acquisition and retention toward it.
Where contribution leaks
The exact dollars lost to returns on high-AOV buyers, discount stacking on customers who'd pay full price, and win-back spend on customers who never come back.

Figures illustrative. Your diagnostic is computed on your customers, from your own order history.
The score, live in the stack you already run.
Forward CLV is a subscription that re-scores daily. Your ESP already knows how to send; it doesn't know who is worth it. Tacet supplies that one missing input.
- Every customer re-scored daily as new orders, returns, and discounts land
- Named properties written to every Klaviyo profile: Forward CLV and its rank, archetype, discount and return bands, and the chance each customer is still active, so your team can segment on them directly, like "Tacet · Top decile forward value"
- New customers scored the morning after their first order, not a year after the spend
- A weekly brief and a monthly report: score movement, new entrants, and one honest read on what changed
How it connects

Tacet · Forward CLV
every customer scored daily, after product costs and expected returns
Klaviyo
profile properties · lists · the segments you build
No new build on your side. In a controlled trial, the winning flow ran entirely inside the client’s existing account.
The month in numbers
The honest read
Value creation held steady. One watch item: new top-decile entrants slowed 8% month over month as acquisition mix drifted toward discount-led channels.
Segments in Klaviyo, refreshed from the properties
Scores refresh daily; this report lands monthly, with a shorter brief each week. Segments built on Tacet’s properties pick the changes up automatically.
Figures illustrative. Your customers are scored daily; the report is computed monthly.
The model nominates the playbook. The experiment renders the verdict.
Playbooks are not templates. Forward CLV identifies which pools of your customers can pay for an intervention, and every playbook ships with its own controlled experiment. The ones that read null get retired.
The play. Proposed by Tacet, built and approved in the portal by your admin, then sent as an email campaign from your own Klaviyo account
The experiment. Read dates and stopping rules set before launch, with a comparison group held back
The verdict. A written read at the end: scale it, or retire it
Built today
A play can be built on any of these once your latest scoring run ranks it for your store. Each one sends as an email campaign from your own Klaviyo account.
One-Timer Conversion
One-time buyers still likely to return
Most DTC customers buy exactly once. This play reaches only the one-timers with a realistic chance of a second order.
Get the free One-Timer Conversion manualSleeping Giant Reactivation
Lapsed customers with a long buying history
Reaches customers with strong purchase histories who have gone quiet but are still likely to be customers, and lets the rest sleep.
Promo Weaning
Customers who have only bought with a discount
Tests whether customers trained to wait for a code will buy without one.
High-Value Protection
The thin top tier
Defends the customers carrying most of your forward value before their churn shows up in a report.
Return Rate Reduction
Repeat buyers likely to send items back
Reaches the repeat buyers most likely to return what they order. A return avoided is margin kept.
The library grows as the model surfaces new pools. A customer held by one play is left out of every other, so plays never compete for the same people.
In development
Not yet something the portal can build, so it is not part of the subscription today.
Subscription Conversion
In developmentRepeat buyers with subscription-shaped cadence
Invites your steadiest repeaters to subscribe. Committed recurring revenue is the most durable asset a DTC book can hold.
