An AI Growth engine for D2C subscription e-commerce brands.

Nothing moves without your approval. Signal over Noise connects Shopify, Klaviyo, your subscription platform and your ad accounts, rebuilds the CAC and LTV you can actually defend, then proposes the next move and runs it once you say yes.

WHAT IT DOES

Trust the numbers. Move the lever. Decide as a team.

Not a dashboard, and not a bag of agents.
01

Numbers you can defend

CAC and LTV rebuilt from raw Shopify, Klaviyo, subscription and ad data on one definition, cited to source.
02

One place to act

Approved moves execute where they land: ad sets and budgets, landing pages, PDP and checkout, lifecycle flows.
03

Decisions that survive the week

Every call becomes a shared thread the growth lead, the CFO and the analyst work inside — in the app, in Slack and in Teams.
See how it works
OPERATOR CONTROL

It proposes. You approve. It executes. You can undo.

Every action passes the same gate: what will change, in which system, what it should move, and a one-click reverse.
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.

We stopped arguing about whether the numbers were right — and started deciding what to do with them.

What changed at two brands.

Good Day Optics · Ski and mountain-bike goggles · Edmonton, Alberta

Good Day Optics closed October 25% above the top of its revenue target, three weeks ahead of the deadline.

“The flow improvement and actually generating revenue… then it’s a no-brainer. Who says no to using something that has already made you more money than what you were currently doing?”

Answers in seconds, not days.

One place to ask the business anything, unifying Notion, GitHub and Klaviyo with live company context. Answers link back to source, so claims are verifiable rather than remembered.

It moved information-gathering off people’s calendars and into a shared system — so the team spends its time deciding, not chasing.
Good Day Optics is named with its permission. The pet food engagement is under NDA and described by sector and geography only. Every figure shown is a measured result rather than a model.
