“Before Creuto, every department was running on its own disconnected spreadsheet. Nihar locked down our operational requirements in the PRD, and his team delivered a unified system that gave our management team real-time visibility for the first time.”

My principles

The principles I live and work by.

Software has felt like magic to me since I was a small boy. Someone touches a button and things just happen. I could never leave it there. I wanted to know how it worked, and then how to use it to solve the next problem. That curiosity is still what I bring to every product we build, and these are the principles I hold myself to.

  1. 01

    Stay humble.

    Things can change overnight. I keep learning, and I stay open to being wrong.

  2. 02

    Keep doing it.

    No matter what, I keep going. There is always a way, and you find it by moving.

  3. 03

    Invest in the right tools.

    I put real time and money into good tools and technology. Cutting corners there always costs more later.

  4. 04

    Work with people who share the vision.

    If the vision and the values don’t match, I would rather not work together. Life is too short.

  5. 05

    Start where you are.

    Begin with what you have, toward what you want. Waiting for perfect conditions is just another way of not starting.

How we work

From first call to a growing product, in six clear steps.

Every phase ends with something you can review, so you keep full control of scope, timeline and budget.

  1. 01

    Discovery Call

    A 45-minute conversation about your idea, users, goals and budget. You leave with a clear read on what to build first.

    OutputClear read on scope

  2. 02

    PRD, Prototype & Proposal

    We write the product requirements document, design a clickable prototype, and send a commercial proposal with fixed scope, timeline and price.

    OutputPRD, prototype and fixed-price proposal

  3. 03

    Build in Sprints

    We split the project into short sprints. After each one you see working software, share feedback, and we adjust. This repeats until the product is complete.

    Sprint 1 → Sprint 2 → Sprint 3 → repeat until launch

    OutputWorking demo after every sprint

  4. 04

    Testing & Deployment

    Functional, performance and security testing, then release to the App Store, Google Play or your cloud with automated CI/CD pipelines.

    OutputTested, live product

Frequently asked questions

Straightforward answers to common questions.

How we work, who owns what, how budgets are set and what happens after launch.

We start with a free 45-minute discovery call. We review your product idea or current operations, identify the key bottlenecks, and decide whether custom software makes sense. If it does, you get a clear scope and estimate within 48 hours, and we begin with a PRD and architecture sprint before any production code is written.
Nothing formal. A rough idea, a few notes or an existing product is enough. If you have competitor examples, sketches or a list of what your users struggle with, bring them along. Turning an unclear idea into a scoped plan is part of the work.
We work on fixed-milestone sprint agreements tied to agreed deliverables. Pricing depends on the functional scope, integrations and market scenario of the project. Because everything is specified upfront in the PRD, you do not face surprise hourly billing or runaway invoices. For a rough first view, the free App Cost Calculator on this site is a useful starting point.
You own 100% of the intellectual property, source code, database schemas, deployment pipelines and design assets from day one. All code is committed directly to your company's own GitHub repositories and cloud infrastructure.
No. All software engineering, database architecture, UI/UX design and quality assurance is carried out by the in-house team at Creuto, led directly by Nihar. You work with one team and one person accountable.
Both. Many projects start with a founder who has an idea and no technical team, and others are established businesses replacing manual processes or ageing systems. The approach is the same: scope what matters first, build it in milestones and keep the roadmap honest.
Yes. Creuto is an OpenAI Select Partner, and we build AI features and agent workflows into existing products as well as new ones. We start from the workflow you want to improve, check that AI is the right tool for it, and ship a small, measurable version first.
Yes. We review what exists, decide what to keep and what to replace, and plan the move in stages so your team can keep working while the new system is built and tested alongside the old one.
We specialise in modern, proven production technologies: TypeScript, React, Next.js, React Native, Node.js, Python/FastAPI, PostgreSQL, Redis, Docker and AWS/Cloudflare. We choose tools based on your long-term operational scale, not on trends.
Asynchronous daily updates via Loom and GitHub, plus live overlap hours each week for stand-ups and demos with founders in the US, EU and APAC. You see working progress regularly instead of waiting for a final reveal.
Yes. Formal mutual non-disclosure agreements are available and signed before any deep architecture or discovery sessions. Client information is kept strictly confidential.
Every production launch includes a 30-to-60-day post-launch warranty covering bug fixes, server telemetry and performance tuning. We also offer ongoing maintenance retainers and help onboard or train your internal developers when you are ready to expand in-house.
