/ Our Approach

Scaling SaaS & B2B Tech brands with App Development since 2017.

A SaaS app - mobile or web - lives or dies on activation rate. The sign-up is cheap; the first-session 'aha moment' is what decides whether a user becomes a paying customer. Building a SaaS app means optimising that first 5 minutes (onboarding, first feature use, first value moment), then layering depth for power users. We build mobile in React Native (shared iOS/Android) with native modules where biometric or platform-specific features demand it, and web apps in Next.js or Remix with modern state management (Zustand, Jotai, or React Query depending on data shape). Before that we instrument the funnel, because a team that cannot see where the first session breaks will redesign the wrong screen with complete confidence. The commonest finding is that activation fails on an empty state, not the signup flow everybody was debating.

SaaS app architecture in 2026 leans heavily on serverless (Vercel, Cloudflare Workers), edge databases (Turso, Neon), and per-tenant data separation that scales without ops overhead. The activation funnel is the critical path: sign-up → verification → onboarding survey → first feature use → first value moment → invite-team/share → paid conversion. Each step has measurable drop-off, and a well-instrumented onboarding can recover 10-30% of users that a default flow would lose. Billing is an underappreciated complexity surface: dunning logic (failed card recovery), subscription changes (upgrade/downgrade with proration), trial-to-paid transitions, and usage-based pricing if applicable. Razorpay for India-only SaaS, Stripe or Paddle for global. Mobile SaaS apps have a specific challenge - Apple's 30% cut on in-app subscriptions makes IAP economically painful for many SaaS products; we handle both IAP and external-billing patterns with proper App Store Review Guidelines compliance. Web apps skew toward Next.js + serverless + tRPC or REST APIs, with feature flags (PostHog, Unleash) wired in for safer rollouts.

Common Questions

Everything you need to know about App Development for SaaS & B2B Tech brands

React Native or native for SaaS mobile?

React Native for 80% of SaaS where UI is form-heavy and data-driven. Native (Swift/Kotlin) where you need deep platform integration - advanced biometrics, document scanning, platform-specific APIs. Most Indian SaaS products we build are React Native.

Razorpay, Stripe or Paddle?

Razorpay for India-only SaaS with INR pricing. Stripe for global with multi-currency, sophisticated billing logic, and US/EU customer base. Paddle for global with simpler billing needs and Merchant-of-Record advantages (handles tax globally). We'll help decide based on your customer geography and billing complexity.

Do you handle App Store IAP for subscriptions?

Yes. Apple's 30% cut is real - we implement both IAP (where required by ASRG 3.1.1) and external-billing patterns with appropriate compliance. For B2B SaaS where buyer is paying on company card not personal Apple ID, external billing with web sign-up is usually the right call.

Can you rebuild our existing SaaS app?

Yes. Typical rebuilds: modernise React Native version, refactor state management (often from Redux to Zustand or React Query), rebuild onboarding funnel for activation, integrate feature flags. Rebuild projects run 16-24 weeks with parallel maintenance on the current app.

Does our SaaS actually need a mobile app?

Most B2B SaaS products do not, and we would rather lose the project than build one that gets installed and abandoned. A mobile app earns its cost when there is a genuine mobile-first job to be done, such as approvals, notifications, field data capture or something that happens away from a desk, and it fails when it is a smaller version of a dashboard that users only ever open on a laptop. The failure signature is predictable, with strong install numbers driven by an announcement and near-zero usage a month later, plus a permanent maintenance obligation across two platforms. A responsive web app plus well-built email and push notifications solves the actual need in a large share of cases.

How do you handle multi-tenant data isolation for enterprise buyers?

Enforce tenancy at the database layer rather than in application logic, because a filter that lives in code will eventually be forgotten in one query and that single omission becomes a disclosure incident. Row-level security policies or genuinely separate schemas mean that isolation holds even when a developer writes a query that forgets the tenant clause, which they will. The trade-off is real: schema separation isolates most strongly but complicates migrations and raises per-tenant overhead, while row-level policies scale more easily and depend on the policies being correct. Enterprise security reviews ask about this directly, so the choice is worth making deliberately before a buyer forces it.

What is the honest timeline from kickoff to a usable first version?

Twelve to twenty weeks for a genuine first version, and any shorter estimate is either scoping something smaller than you described or assuming nothing goes wrong. That range assumes a defined feature set, an available decision-maker on your side and no dependency on a third-party system with poor documentation, which is the variable that most often breaks estimates. The phases are roughly four weeks of design and architecture, eight to twelve of build, and two to four of stabilisation and load testing, with app store review adding a further one to three weeks on mobile. We would rather set that expectation at proposal stage than discover it at week ten.

Can you take over an app another team built and left unfinished?

Yes, and we start with a paid two to three week audit before committing to any timeline, because inheriting an unfamiliar codebase without one produces estimates that are close to fiction. The audit covers dependency currency, test coverage, architectural decisions that constrain future work, security exposure and whether the remaining scope is better completed or rewritten. Roughly half the handovers we assess are worth continuing, and where a rewrite is the honest answer we say so with the reasoning rather than quietly rebuilding under the label of maintenance. Access to the original team for even a few hours of context materially improves the outcome.
