THE JOB
Why is my CAC different in Shopify and Meta?
Shopify says one CAC, Meta claims another, the agency deck shows a third. Every weekly meeting starts by arguing about whose number is right instead of deciding what to do next, and the decision moves to Thursday.Nobody is wrong. Each number was produced by someone doing their job well in their own tool. What is missing is one definition, built from the raw rows, that all three can check.
ONE NUMBER
What changes when there is one governed number?
Cohort LTV forecast within 3.6% of actual at week four, in one engagement.
When the number is rebuilt from your own raw data on one governed definition, the argument ends before the meeting starts. Spend decisions that used to wait on three, six and twelve months of actuals run on a four-week forecast.

HOW IT HELPS
How does Signal over Noise help a D2C founder?
One number you can defend
CAC and LTV rebuilt from raw Shopify, Klaviyo, subscription and ad data on one definition, cited to source.
Moves, not dashboards
Each proposal arrives with its evidence and expected effect. You approve, change or reject.
Execution without handover
Approved moves run in the ad account, storefront or lifecycle tool they belong to.
Decisions that survive the week
Shared decision threads in the app, Slack and Teams keep the why beside the what.
PROPOSE · APPROVE · EXECUTE · REVERSE
What happens when it proposes a move?
The loop is built around control. Spending and publishing are separate permissions, so the founder can hold one and delegate the other, and a wrong call costs one click to reverse inside 14 days. The Pulse card below is the kind of move that usually takes a week of analysis, shipped in one approval.
01
Propose
Each move arrives with its evidence and its expected effect, cited to source.
02
Approve
You approve, change or reject. Permissions are role-scoped: spending and publishing are separate rights.
03
Execute
The approved move runs in the system it belongs to. No copy-paste, no handover.
04
Reverse
One click puts it back, and the log keeps who approved it, when, and on what evidence.

FAQ
What do founders ask before they sign up?
Signal over Noise is an AI growth engine for D2C subscription e-commerce brands. Approval-gated, reversible, logged. It connects the operating stack, rebuilds CAC and cohort LTV from raw data on one governed definition cited to source, proposes the next growth move with its evidence, and executes it only after approval. From $500/month, no application, no lock-in.
Dashboards report numbers; Signal over Noise governs one definition and acts on approval. It rebuilds blended CAC and cohort LTV from raw spend, order and subscription data rather than reading another tool’s output, then proposes and executes moves. Triple Whale is a supported integration, not a replacement target: the two coexist.
Yes. Every spend change passes an approval gate under role-scoped permissions, where spending and publishing are separate rights. Any approved move reverses in one click for 14 days, and the log records who approved it, when, and on what evidence.
Blended CAC is total acquisition spend divided by the new customers acquired in the period, rebuilt from raw spend and order data on one governed definition rather than taken from any single ad platform’s attribution.
Core connection takes 30 minutes for the standard subscription stack, and the first approved moves run inside two weeks.
