Revenue you can audit.
Drackle connects read-only to your Stripe and auth, ranks every free user by likelihood to pay, and converts them — in-product, by email, or with a note your founder sends. Every campaign holds back a control group, so the lift it reports is measured, not claimed.

They're buried in your free tier — and they stay invisible three ways.
The free tier fills with thousands of users — and converts in the low single digits.
Upgrade intent sits in Stripe and auth events no human ever reads.
Emails and banners ship, revenue moves — and nobody can say what caused what.
Drackle was built against all three — an agent that reads the signal and acts, a holdout that proves what it caused.
Three pipelines. One afternoon.
Nothing here requires an SDK, a warehouse, or an engineering sprint.
Connect Stripe and your auth. That's the integration.
Read-only OAuth to Stripe and to Clerk, Supabase Auth, or Firebase Auth gives Drackle a complete map of every free and paying user — plans, invoices, seats, sign-ins. If you run PostHog, Amplitude, or Mixpanel, usage events enrich the picture. They're optional.
Every user, ranked by revenue likelihood.
Each user and account is scored on likelihood to convert from free to paid, or to move up a plan — from signals like credit exhaustion, seat growth, plan-limit hits, invoice behavior, and trial timing. Every prediction is recorded in the ledger, so you can check them against what happened.
Nudges in-product. Email under your brand. Founders for the big ones.
High-intent users see well-timed upgrade prompts and paywall moments inside the product. Warm lifecycle email goes out from your own domain. For the highest-value accounts, Drackle drafts the note and pings your founder in Slack to send it personally. Cold outbound does not exist here.
Plugs into the stack you already run.
Stripe and one auth source are enough to start. Everything else just makes the scoring sharper.

Every campaign runs against a holdout.
A random slice of eligible users is set aside and never touched. What they convert at is the baseline; what the treated group converts at is the result. Drackle reports the difference in dollars — and bills on nothing else.
Priced on proof.
A monthly platform fee, plus a share of the lift the holdout proves. No seats, no annual lock-in.
You only pay the performance fee on revenue we prove we created — measured against a holdout group we hold back automatically.
For self-serve, Stripe + auth only.

hello@drackle.com →the cap exists so cost is never a surprise — on Starter and Growth, your total is never more than $2,000 in a month.
Deliberately narrow.
Drackle is built for a specific company at a specific stage. If the left column reads like yours, setup is an afternoon and the first ledger arrives within a billing cycle.
