SaaS & Mobile Apps
From validated idea to product in your users' hands. We build revenue-generating custom SaaS platforms and native-quality iOS and Android apps — authentication, billing, multi-tenancy, and offline-first architecture — engineered to scale without painful rewrites.
Everything you need
Full-Stack Next.js & TypeScript
Your entire SaaS platform in one cohesive, type-safe codebase — Next.js App Router serving both the front-end and API, TypeScript across every layer, and PostgreSQL via Supabase or Neon for a scalable, auditable data foundation that grows with your user base.
Auth & Role-Based Access Control
JWT-based authentication with social login, magic links, secure session management, and granular role-based access control — plus Face ID and Touch ID biometrics on mobile — wired up with proper security practices before the first screen ships to a user.
Stripe Billing & Subscriptions
Subscription tiers, free trials, usage-based metering, mid-cycle proration, in-app purchases, and a fully self-serve billing portal — every billing edge case handled correctly from day one so you never lose revenue to confusing checkout or upgrade flows.
Native iOS & Android Apps
Production-grade apps built in React Native or Flutter from one shared codebase targeting both platforms — truly native UI components, platform-specific conventions, and consistent 60fps rendering throughout, never web-view workarounds that feel second-class to users.
Push, Offline & Native Device APIs
FCM and APNs push with deep linking, offline-first sync with conflict resolution, plus camera, GPS, Bluetooth, NFC, and HealthKit integration — so your app feels instant and reliable even on a poor connection and taps capabilities the mobile web cannot reach.
CI/CD, Monitoring & Analytics
Vercel CI/CD with per-branch preview environments, Sentry error tracking with source maps, Expo OTA updates for instant mobile fixes, and PostHog or Mixpanel funnels — so your team ships with confidence and improves product metrics without guessing.
Our process
Validate & Architect
We run a focused product sprint to scope your MVP ruthlessly, map core flows, choose the platform stack — Next.js for the SaaS layer, React Native or Flutter for mobile — define the data model, and validate that the product solves a real, prioritised problem before a pixel is designed.
Design & Prototype
A complete design pass covers onboarding, the product dashboard, every key flow, and critical empty and error states — mobile-first with iOS HIG and Material Design 3 conventions, delivered as an interactive Figma prototype usability-tested on real devices and mapped to a tokenised component library.
Build & Harden
We build the full product in one codebase — auth, role-based access, Stripe billing, native device APIs, offline sync, and push — shipping daily Vercel previews and TestFlight and Play Console builds so you test on real infrastructure and real hardware as features land, not at the end.
Launch & Grow
Before go-live we run a security review, wire up Sentry, instrument analytics, and performance-tune critical paths — then manage App Store and Play Store submission end to end, optimise listings for organic discovery, and monitor uptime, crash rates, and retention through the first weeks live.
How we build it
Common questions
Most MVPs launch in 6–10 weeks from the start of the product sprint, whether it's a SaaS platform, a native app, or both. We scope ruthlessly up front to protect that window — the goal is a real, billable product in users' hands, not a perfect one. Anything beyond the MVP is sequenced into a post-launch roadmap so momentum continues after go-live.
Yes — billing is standard on every product we deliver. For SaaS we configure subscription tiers, free trials, usage-based metering, proration, failed payment handling, and a self-serve customer portal via Stripe. For mobile we wire up App Store and Play Store in-app purchases. Every flow is tested in Stripe's test mode before launch, so there are no surprises with real revenue.
Both are mature, production-proven frameworks that produce genuine native apps. React Native is stronger when your team has JavaScript or React knowledge or you're sharing logic with a Next.js platform — the curve is lower and the ecosystem broader. Flutter wins when you need pixel-perfect custom UI or complex animations. We assess your requirements on the discovery call and give a concrete recommendation with the rationale.
Our standard stack is Next.js and TypeScript for the full-stack SaaS application, PostgreSQL via Supabase or Neon, Stripe for billing, and Vercel for CI/CD — with React Native or Flutter and Expo for native iOS and Android. We add Sentry for error monitoring and PostHog or Mixpanel for product analytics. We'll recommend deviations if your specific requirements call for them.
We offer flexible monthly retainers covering bug fixes triggered by new iOS, Android, and platform releases, feature work prioritised from your roadmap, ongoing App Store Optimisation, and Expo OTA updates that push mobile fixes without waiting for App Store review. For SaaS we maintain CI/CD, monitoring, and billing. Some clients need minimal maintenance, others an ongoing development cadence.
