Isai’s Logic

We build digital products people actually use.

A software, design and engineering studio building mobile products, web platforms, business software, automation and AI-powered experiences.

We don’t just build software. We turn ideas and business problems into products people actually use.

What we do

From idea to software that works.

A feature list is not a product. We start from the problem, design the experience, engineer the system — and stay until it works in people’s hands.

  • 01

    Mobile Products

    iOS and Android apps — native or cross-platform, built offline-first and taken all the way through store release.

    UI/UX Design

    Product strategy, interaction design, design systems and prototypes you can hold before a line of code is written.

Good software starts before the code.

  5. Outcome

We start with what is actually broken — the queue, the paper card, the wrong part. Not the feature list.

Design + Engineering

One team. No hand-offs.

Design that understands technology.

Our designers know what an API can return, what a phone can cache and what a database can index — so every screen we draw is one we can actually ship.

Engineering that understands people.

Our engineers sit in on research and design reviews. They care how it feels on a slow network, on a small screen, at the busiest hour of the day.

Research → UX → UI → Architecture → Development → Launch → Evolution

Technology

The stack follows the problem.

We pick what keeps your product fast, maintainable and easy to evolve — not what looks modern.

Interface

What people touch

  • ReactComponent-driven interfaces
  • Next.jsFast, SEO-friendly web platforms
  • TypeScriptTyped codebases end to end
  • Tailwind CSSDesign-system styling at speed

Mobile

Products in pockets

  • React NativeOne codebase, two stores
  • iOSNative modules where it matters
  • AndroidTested across real devices

Backend

Services & logic

  • Node.jsAPIs and real-time services
  • PythonData work, ML and automation
  • RESTClear, documented contracts
  • WebSocketsLive order and status updates

Data

Truth, stored well

  • PostgreSQLRelational core for commerce & ops
  • MongoDBFlexible documents and catalogues
  • FirebaseAuth, sync and offline-first apps

Cloud

Ship & scale

  • AWSScalable infrastructure
  • CloudflareGlobal delivery and security
  • CI/CDEvery change reviewed and deployed
  • EdgeLogic close to the user

Intelligence

Where AI earns its place

  • AI / MLModels applied to real workflows
  • LLM IntegrationAssistants, search, document AI
  • AutomationHours of manual work, removed

Process

Six stages.
One clear path.

  1. 01

    Discover

    We learn the business, the people who'll use it and the constraints that are real.

  2. 02

    Define

    Scope, architecture and success criteria — written down, agreed, and small enough to ship.

  3. 03

    Design

    Flows, interfaces and system decisions, prototyped and tested with real users.

  4. 04

    Build

    Engineering in reviewable increments on a clean architecture. You see progress every week.

  5. 05

    Launch

    Release, instrumentation and the operational details that make day one boring — in the good way.

  6. 06

    Evolve

    We stay. Usage data shapes what comes next, and the product keeps getting better.

Why Isai’s Logic

Built by people who stay.

  1. Product thinking

    We ask what it's for before we ask what it's built with.

  2. Design-led development

    Designers and engineers work together daily — not in hand-offs.

  3. Modern engineering

    Typed codebases, reviewed changes, automated deployment pipelines.

  4. Scalable architecture

    Designed to evolve with the product, without the big rewrite.

  5. Business-focused

    Software that moves a number that matters — orders taken, hours saved, customers retained.

  6. Long-term partnership

    We stay involved after launch. The version that ships next year matters too.

About the studio

Small enough to care. Technical enough to build.

Product thinkingDesignEngineeringBusiness understandingIsai’s Logic

We’re a focused studio in India. The people you talk to on the first call are the people who design and build your product — no account managers, no hand-offs, no lost context.

We like hard problems with real users on the other side: a calendar people open every morning, a parts catalogue a factory depends on, a canteen at lunch rush.

Have a difficult problem? Let’s build the right thing.

Tell us what you’re trying to build. We’ll help you understand the scope, shape and technology required to turn it into a real product.
