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.

This is the diagnostic. Yours arrives on your data.
The free analysis returns a read like this: customer tiers, value concentration, named leak sources, and the model's own back-test on your history.
A forward CLV score for every customer
Not what a customer has spent, but what they will contribute, in dollars, net of returns and discounts. Scored the day they place 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.
The back-test, published
How well the model predicted a slice of your own history it never saw: aggregate revenue accuracy and value-ranking accuracy, before anything directs a dollar.

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 value and archetype, so your team can segment on them directly, like "Tacet · Top decile forward value"
- New high-value customers flagged the day they enter, not a year after the spend
- A monthly brief: score movement, new entrants, and one honest read on what changed
How it connects
Shopify
orders · returns · discounts · read-only
Tacet · Forward CLV
every customer scored daily, net of returns
Klaviyo
segments · profile properties · paid audiences
No new build on your side. In a recent 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 brief lands monthly. Your flows and paid audiences pick the changes up automatically.
Figures illustrative. Your customers are scored daily; the brief 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 flow. Built in your own Klaviyo account, sent only after your admin approves it
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
Second Purchase
High-value one-time buyers
Roughly four in five DTC customers buy exactly once, and a second purchase multiplies expected value five to nine times depending on category. This playbook spends only on the one-timers worth converting.
Get the free manualSubscription Conversion
Repeat buyers with subscription-shaped cadence
Converts your steadiest repeaters into committed recurring revenue, the most durable asset a DTC book can hold.
Sleeping Giants
Dormant high-value customers
Wakes the lapsed customers whose forward value justifies the spend, and lets the rest sleep.
High-Value Protection
The thin top tier
Defends the customers carrying most of your forward value before their churn shows up in a report.
Discount Weaning
Promo-dependent repeaters
Recovers margin from customers trained to wait for a code, without losing them.
The library grows as the model surfaces new pools. Each playbook targets a non-overlapping set of customers, so the value stacks rather than competes.
