Reconciled to the cent
Attributed revenue plus direct/unknown always equals your net Stripe MRR for the period. No black-box confidence score — every figure ties back to a transaction you can open in Stripe.
About Signal Sparrow
Attribution that starts from Stripe revenue, not pixel guesses.
Signal Sparrow is a Stripe-first conversion-tracking and revenue-attribution platform, built for B2B SaaS teams who are tired of ad platforms and analytics tools disagreeing about which campaigns actually grow MRR. We start every number from your real Stripe revenue and work backward to the channel that earned it.
Why we built this
Every ad platform reports a different number. Only Stripe knows the truth.
Meta says a campaign drove 40 signups. Google says it drove 55. GA4 disagrees with both — and none of them can see whether a single one of those signups ever paid. For a subscription business, that gap is the whole problem: platforms optimize toward cheap trials, not toward customers who convert and stay.
Signal Sparrow exists to close that gap. It connects to Stripe read-only, captures the clicks that pixels and blockers miss with a first-party snippet, and resolves every conversion back to the campaign that earned it — so the number you report is the number in your bank account, not an estimate.

Four principles behind every feature we ship.
- 02
Privacy by default
Emails are matched by keyed hash before anything is forwarded to an ad platform. IP addresses are transformed into a one-way hash before storage. We never sell data.
- 03
Self-serve, always
Public, month-to-month pricing and no sales call to see a number or start a trial. Connect Stripe, add the snippet, and see reconciled attribution the same day.
- 04
Built for Stripe SaaS
Not a Shopify tool retrofitted for subscriptions. Signal Sparrow understands MRR, expansion, downgrades, and churn the way a subscription business actually experiences them.
The number we build around
One equation that has to hold.

Attributed plus direct/unknown always equals net MRR for the period — it is how every Signal Sparrow report reconciles, and what we check before we show you a number.

How we operate
Focused on one job: attribution you can trust.
Signal Sparrow is built around a single problem — reconciling ad spend to real Stripe revenue — instead of chasing every marketing-analytics use case. That focus means a simpler product, fewer things that can break, and support that responds directly instead of routing you through a ticket queue.

Nothing about how we handle data is hidden.
Because Signal Sparrow processes data on behalf of the B2B SaaS teams that use it, every policy is written for you to read before you connect Stripe — not after.
TLS in transit, encryption at rest, and hashed identifiers before anything leaves the platform.
Questions, answered.
Everything teams ask before switching their attribution to Stripe truth. Still curious? Talk to us.
Every report starts from your real Stripe subscription revenue, not from pixel estimates. Attribution, ROAS, CAC payback and cohorts are all computed from actual transactions, so the numbers reconcile to what is in your Stripe account instead of a platform-reported estimate.
Subscription revenue behaves differently from one-off ecommerce sales — MRR, expansion, downgrades and churn all need to be understood correctly for attribution to mean anything. Staying focused on Stripe-billed SaaS lets the product model that correctly instead of being a generic analytics tool retrofitted for subscriptions.

No. We do not sell personal data and do not share it for cross-context behavioral advertising. Identifiers are hashed before being forwarded to any ad platform you connect, and only on your instruction.
