reports a different ROI.
None of them are yours.
We turn raw data into clear profitability information, so your biggest financial decisions make themselves.
We make your numbers agree.
Every source, reconciled into one number.
Every metric built to your definitions, then maintained by us.
ROI that means the same thing on every channel.
The real return per channel and cohort — after refunds and churn.
We flag the moment your CAC or margin moves.
We build connectors for whatever’s in your stack.
Every tool has its own definition of “return,” and a CRM that never agrees with any of them.
We reconcile them to the one number your business actually runs on.
Not a dashboard. A data team on the hook for your numbers.
We’re finance-first founders who’ve been accountable for these exact numbers. So we understand the business question before writing a line of code, and we monitor your data 24/7.
We’ve owned these numbers ourselves, we know which ones matter and what a wrong one costs.
Custom pipelines, metrics, and connectors, built from scratch around how your business actually works.
We watch your data around the clock and tell you what’s happening, not just when you go looking.
A data operation built around your business, not a template.
We scope it with you, build every layer by hand, and run it for you.
Every ad channel and your CRM — Google, Meta, Microsoft, TikTok, LinkedIn — plus your billing and revenue data, pulled into one place.
Your own warehouse on BigQuery or AWS, deduplicated and joined, with your full history backfilled from day one.
ROI, CAC, LTV, ARPU, churn, approval and refund rates — calculated to your definitions, not a generic formula imposed on you.
Role-based dashboards, custom reports, and intelligent alerts to Slack or Teams, monitored 24/7 — so the right number reaches the right person, in context.
Watch the noise resolve into one number you can trust.
Each channel reports returns its own way. Drag the handle — and watch them reconcile into the one number your business actually runs on.
Answers, not just dashboards.
A working library of proven reports — each one built to answer a decision, not just draw a chart.
What it truly costs to acquire on each channel — comparable across every app, plan, and period.
Whether you’ll hit the month — spend, users, and CAC against target, with daily nudges to stay on track.
How any slice of customers actually performs — build a cohort on any variables, instantly, no query queue.
Any metric broken to any level — app, plan, or channel — in one view, without an export.
Which cohorts carry the business — quality and quantity together, and each one’s share of profit or loss.
If you can define the question, we build the report — your metrics, your granularity, your cadence.
Talk to the team →Built for one situation
and built for it completely.
Plumb earns its place where ad spend and subscription revenue are both significant, and the connection between them is currently unclear or unmeasured.
Recurring billing — monthly, annual, or usage-based — where LTV is the number that matters.
Running two or more paid channels. The more channels, the harder attribution — and the more Plumb pays for itself.
Subscription revenue in a CRM or billing system — the half of ROI ad platforms never see.
Already on BigQuery, AWS, or Azure — or open to it. No on-premise requirement, no forced migration.
The people accountable for CAC, LTV, and budget — who need one number everyone can trust.
Deciding where the next dollar goes, and tired of basing it on numbers that don’t reconcile.
Sweet spot: spending across Google, Meta, and at least one more channel, with subscription revenue in your CRM. If that’s you, every part of Plumb was built for exactly that situation.
Not a demo. A conversation with the data team.
