Signal Sparrow
Product — Revenue attribution

SaaS marketing attribution, tied to Stripe revenue.

Meta, Google and GA4 each claim a different number of conversions — and none of them can see your MRR. Signal Sparrow starts with Stripe as the source of truth and traces every dollar of recurring revenue back to the campaign, ad and keyword that earned it.

What is SaaS marketing attribution?

Connect paid acquisition to recurring revenue — not trials.

SaaS marketing attribution is the practice of connecting paid acquisition to the recurring revenue those efforts actually produce, rather than to one-off events like a free-trial signup.

For subscription businesses, that distinction is the whole game. A trial start is not revenue. An upgrade, a renewal and a churn all change what a campaign is truly worth. Signal Sparrow follows the customer from the first ad click through trial, conversion, expansion and retention — across devices and weeks of delay — and expresses the result in MRR, CAC and payback months.

Why pixels under-report SaaS revenue

Your dashboards disagree for a reason — and it is not a tagging bug.

Pixel-based attribution was built for one-click e-commerce, not for trial-led subscriptions. Signal Sparrow closes all three gaps with first-party, server-side tracking and Stripe as the system of record.

Pixel optimizes forThe cheapest signup
Problem 01

Trials are not revenue

Browser pixels optimize toward the cheapest signup, not the most valuable customer. So your ad platforms scale the campaigns that produce $0 trials and starve the ones that produce paying subscribers.

Problem 02

The conversion happens later, in Stripe

A visitor clicks a Meta ad on mobile, starts a 14-day trial, then converts to paid on desktop a week later. The pixel saw a $0 event; the $149/mo subscription is invisible to it.

Problem 03

iOS, ITP and ad blockers hide visitors

Apple's App Tracking Transparency, Safari/Firefox ITP and ad blockers silently drop an estimated 10–30% of conversions before a client-side pixel ever fires.

How it works

    A lightweight, cookieless snippet records fbclid, gclid, UTMs, landing page and referrer server-side, from your own domain.

    Make Stripe your source of truth

    Connect Stripe in one click, read-only. Subscriptions, expansion and churn normalize into SaaS-native events with MRR computed correctly.

    Forward revenue-backed conversions server-side to Meta, Google, TikTok, and LinkedIn so algorithms optimize toward MRR.

Attribution models

First-click, last-click and multi-touch — side by side.

There is no single "correct" model, so Signal Sparrow computes several and shows them honestly labeled — never blended into a score you cannot audit.

Reconciled to Stripe

If it doesn't tie out to Stripe, we tell you.

Signal Sparrow proves itself against Stripe on every screen. Attributed revenue plus direct/unknown must equal your Stripe net MRR for the period, to the cent. When something drifts — a tracking gap, a delayed webhook — you get a data-health warning instead of a confident-looking number that's quietly wrong.

Attribution should not be read-only. Signal Sparrow forwards revenue-backed conversions server-side to every major platform, so their algorithms optimize toward MRR instead of cheap trials.

Questions, answered.

Everything teams ask before switching their attribution to Stripe truth. Still curious? Talk to us.

It's connecting ad spend to the recurring revenue it produces — MRR, expansion and retention — rather than to free-trial signups or pixel events. Signal Sparrow uses Stripe as ground truth to attribute revenue to the exact campaign that earned it.

GA4 and ad pixels report their own conversions with their own windows, so the numbers never agree — and none of them see Stripe MRR. Signal Sparrow attributes paid spend to real subscription revenue and reconciles every view to Stripe to the cent.

Yes. First-click, last-click and multi-touch models (linear, time-decay, u-shaped) are computed and shown side by side, and you can re-attribute your history instantly when you change the model or lookback window.

An identity graph links anonymous visitors to your identify() calls and to Stripe customers, so a mobile click and a later desktop conversion resolve to one customer — even weeks apart — and credit flows to the originating campaign.

Yes. Every channel and campaign shows attributed MRR, CAC, CAC payback in months, revenue-based ROAS and cohort retention — all tied to Stripe.

About 30 minutes. Add the first-party snippet and connect Stripe and your ad accounts over OAuth — no API keys, no data team, no sales call.
