- KeepBrings paying customers at a cost you can live with.
- Cut or move budgetCosts more per paying customer than your other campaigns. The plan names the amount and the reason.
- Too few to tellFewer than 30 paying customers. We show the counts and give no verdict.
- No change this weekA valid plan. We do not invent work to look busy.
Ad platforms report clicks and sign-ups. Datarithms matches your ad spend to the customers who actually paid, and gives you a short weekly plan: what to keep, what to cut, and what is still too early to judge.
Early access: we prepare your weekly plan with you from your own exports while the direct connections are built.
The problem
A cheap sign-up is not a cheap customer.
Different counts
Each platform counts its own conversions in its own way. Added together, they claim more customers than you have.
Wrong target
Campaigns tuned for sign-ups can fill your trial list with people who never pay. The platform reports that as success.
No follow-up
You change a budget and move on. Nobody checks four weeks later whether the change brought more paying customers or fewer.
How it works
Three steps, then one short list each week.
You share your ad and payment data
Today: exports from Google, Meta, TikTok and LinkedIn ads, plus Stripe or HubSpot for who paid or became a qualified lead. Direct read-only connections are being built.
We match each paying customer to the ad they clicked
Last ad click within 90 days. Customers refunded within 14 days do not count. Customers we cannot match are shown as unmatched, never guessed.
You get a weekly plan and decide each change
A few proposed changes with the numbers behind them. Nothing changes in your ad accounts without your approval. Each change is checked again after 28 days.
Who it is for
Teams that pay for ads and get paid later.
Software and service companies
You advertise for sign-ups, trials or leads, and the money arrives days or weeks afterwards through Stripe or a sales pipeline. You want to know which spend ends in revenue.
Agencies
You run ads for clients and need a dated record of each change and what happened next, in paying customers, to show at the monthly review.
