Custom software development India

Custom software built in India for US companies

We are a software and AI development studio in India that builds bespoke products for US clients. If an off-the-shelf tool almost fits but not quite, we design and ship the version that actually does, with senior engineers, a daily overlap with your hours, and full ownership handed back to you.

When custom beats off-the-shelf

Buying software is the right call more often than people admit. If a SaaS product covers your need and your team will adopt it, buy it and move on. Custom development earns its keep when the software is the business rather than a back-office convenience.

We see three patterns. The first is workflow that no vendor models, where your process is the edge and bending it to fit a generic tool throws that edge away. The second is integration, when data is scattered across systems that were never meant to talk and the glue is the product. The third is leverage, where a feature only you can offer becomes the reason customers pick you. In those cases a tailored build pays for itself, and the licensing fees you skip often cover much of the work.

What we build

We are a full-stack product team, so the work spans the whole surface of a modern application rather than one slice of it.

  • Web applications. Customer portals, dashboards, billing flows, and admin panels that hold up under real traffic.
  • Mobile apps. iOS and Android, built once with React Native or natively when the use case demands it.
  • APIs and integrations. Clean, versioned APIs and the connective work that ties your CRM, payments, and data warehouse together.
  • Internal tools. Operations software your team uses every day, the unglamorous systems that quietly run the company.
  • AI features. Search over your documents, classification, extraction, and agent workflows added to new or existing products.

How we work

We start small on purpose. The first week is scoping, where we map the problem, agree on what the first release has to do, and cut everything that can wait. Then we build in short cycles and put something clickable in front of you fast, because a real prototype surfaces the things a spec never will.

You get a demo every week and direct access to the engineers doing the work, not a layer of account managers relaying messages. We ship to a staging environment continuously, so progress is something you can touch instead of read about in a status report. When the slice is right, we widen it. When it is wrong, we have lost days rather than months.

The stack and why we use it

We pick tools that a future team can still hire for, not whatever is trending this quarter. On the front end that means React and Next.js with TypeScript, which keep large codebases readable and catch a whole class of bugs before they ship. On the back end we lean on Node and Python, with Postgres as the default database because it is dependable, well understood, and rarely the thing that surprises you at scale.

For AI work we use the model that fits the job rather than a single vendor, pairing it with pgvector or a dedicated vector store for retrieval and LangGraph when a workflow needs real orchestration. We deploy on infrastructure you control, hand over the keys, and document the decisions so the next engineer to open the repo understands why it looks the way it does.

Why FoundrySoft

Plenty of studios can write code. The reasons US clients stay with us are more practical than that. We hold a daily overlap with your business hours, so decisions happen in real time and the project never stalls waiting for a reply across twelve time zones. You own everything outright, with 100 percent of the IP and source assigned to you, no shared libraries quietly tying you to us.

The people on your project are senior engineers who have shipped production systems, not juniors learning on your budget. And we move in weeks, not months, because we would rather prove an idea works early than disappear for a quarter and hope. The result is software you can run, change, and grow without us in the room.

Frequently asked questions

How much does custom software development in India cost?

It depends on scope, but most projects we take on land between $15,000 and $120,000. A focused internal tool or MVP sits at the lower end, while a multi-module platform with AI features and integrations sits higher. We give you a fixed range after a short scoping call, not an open-ended hourly meter, so you know the ceiling before we write a line of code.

How do you handle the time zone gap between India and the US?

We keep a daily overlap window with US business hours, usually four to five hours in your afternoon. Standups, demos, and decisions happen live during that window. Heads-down build work continues while you sleep, so you often wake up to progress rather than waiting a full day for a reply.

Who owns the code and the intellectual property?

You do. Every contract assigns 100 percent of the IP, source code, and design assets to you on payment. We do not reuse your code in other client work, and we hand over the repositories, infrastructure access, and documentation so you are never locked in to us.

Can you add AI features to software we already have?

Yes, and this is a large part of what we do. We plug retrieval, classification, document parsing, and agent workflows into existing products without a rewrite. We start with one feature that pays for itself, prove it in production, then expand from there.

How quickly can we see something working?

A usable first version in weeks, not months. We ship a thin slice of real functionality early so you can click through it, test it with users, and correct course before the budget is committed. Most clients have a working prototype in three to five weeks.
