Natively integrated with your billing & data stack
One platform. Five modules.
A unified growth stack active from day one. Native paywalls, product analytics, messaging, surveys, and authentication — all sharing one customer record, one event stream, and one bill.
The leanest tech stack for modern subscription apps. One clean SDK across web and mobile with zero glue code.

Sell subscriptions on iOS, Android, and the web. No-code builder, A/B tests, virtual currency.

What if your stack actually talked to itself?
Journeys is the workflow engine that connects every BillDog module. A paywall test fails → analytics segments the user → a triggered survey asks why → a personalized message follows up. All in one tool.
The workflow engine no other paywall, messaging, or analytics platform ships.
A focused tool for every job.
Each module stands on its own — competitive with the dedicated tools you'd otherwise stitch together.
Native paywalls on every platform you ship to.
Build subscription paywalls once and ship them on iOS, Android, React Native, Flutter, Expo, and Web — or on any platform via our Universal REST API and BillDog Headless. No-code visual builder for designers, full SDK control for engineers, A/B testing baked in, plus offerings, entitlements, and virtual currency in one stack.
- 6 client SDKs + Universal REST API
- No-code paywall builder
- A/B testing built in
- Offerings + entitlements + virtual currency
Complete product analytics wired directly into subscription revenue.
Map the entire user journey from first tap to renewal. Custom event funnels, cohort retention curves, feature adoption, session replay, and B2B group analytics — unified with real-time MRR and paywall conversion data. Replace standalone analytics tools without extra SDK overhead.
- Full user journey mapping & custom funnels
- Real-time cohort retention & LTV analysis
- Session replay & feature flags built in
- Direct warehouse exports (Snowflake, BigQuery, S3)
Push, in-app, email, SMS — triggered by any event.
Reach users on the channel that fits the moment. Push across iOS (APNs), Android (FCM) and web. In-app overlays. Email through your existing provider. SMS through your own Twilio account, so you pay the carrier directly (managed sending is coming soon). Multi-channel campaigns, A/B variants, segmentation, frequency caps, and quiet hours — all driven by the same events your analytics records.
- Push, in-app, email, SMS in one platform
- Multi-channel campaign orchestration
- Segmentation + A/B + frequency caps
- Triggered by analytics events directly
Ask at the moment it matters. Act on the answer.
Capture feedback right after paywall drop-offs, onboarding friction, or subscription cancellations. Branching logic follows up on each answer, and a completed survey can start a journey — a tailored win-back offer for a cancellation reason, a follow-up message for a low NPS.
- NPS, CSAT, PMF and cancellation templates
- Branching logic & audience targeting
- Responses flow directly into Analytics segments
- A completed survey can start a journey
Sign-in that already knows what they paid for.
Passwords, email and SMS codes, Google, Apple and passkeys, with TOTP and backup codes on top. Your backend verifies the session token offline against a per-environment key set — no call to us on the request path — and the user’s entitlements travel inside it, so gating a paid feature is a signature check rather than a round trip. Organizations, roles and enterprise SSO for the customers who ask for them.
- Passwords, codes, Google, Apple, passkeys, TOTP
- Entitlements carried in the token, verified offline
- Organizations, roles, invitations, verified domains
- Enterprise SAML and OIDC SSO with SCIM
Pricing that scales with you.
Enterprise features at indie prices. Pay only for what you use — SSO, SCIM, AI translation and MCP unlocked from CortX AI Core, no enterprise contract.
Revenue-share. Virtual Currency included.
