Mobile app

Where they use it every day.

Featured concepts

Products with a point of view.

Each concept starts from a real business problem and is designed as a complete product — not a dribbble shot. They're labelled as concepts because they are; the thinking is what we bring to your product.

Concept product · demo data

Financial operations for growing Indian businesses.

A finance operations platform that connects bank accounts, invoicing, payables and reconciliation so founders and finance teams see real cash — not last month's spreadsheet.

The problem

Finance runs on bank portals, Tally exports and a spreadsheet nobody trusts.

For founders

From idea to first version.

We help founders move from a sentence to a product customers can use — with the scoping discipline to ship something that tests the idea, and the engineering to keep building on it.

  1. 01

    Idea

    → Discovery call

    A problem worth solving and a hunch about who has it.

  2. 02

    Validation

    → Product brief

    Interviews, competitor teardown, riskiest assumption named.

  3. 03

    UX

    → Flows & wireframes

    Core journey mapped; scope cut to what proves the idea.

  4. 04

    Prototype

    → Tested prototype

    A clickable product tested with real users.

  5. 05

    MVP

    → Live first version

    Auth, payments, admin and analytics — production-grade.

  6. 06

    Launch

    → Launch & roadmap

    Stores, monitoring, onboarding and a metrics review.

Why work with us

  • Unit, integration and end-to-end tests
  • Preview deployments per pull request
Security
  • OWASP-aware development
  • Secrets in vaults, never in code
  • Dependency and container scanning
  • Least-privilege access
Performance
  • Core Web Vitals budgets
  • Load testing before launch
  • Caching and query review
Transparency
  • Shared project board
  • Fortnightly demos
  • Written decision log
  • Weekly status notes

Products, not projects

We measure ourselves by whether the thing gets used, not whether the ticket got closed.

Show the work

A working build every two weeks. Shared boards, open repositories, written decisions.

Engineering standards are not optional

Tests, code review, CI/CD, security reviews and performance budgets on every project.

Design and engineering in one room

Designers and engineers make decisions together, so designs ship as intended.

Honest scoping

We'll tell you what to cut, what to delay and when not to build at all.

You own everything

Code, designs, accounts and documentation are yours from day one.

FAQ

Questions founders and teams ask first.

What kind of companies do you work with?

Founders with a new product idea, SMEs replacing spreadsheets with software, growing businesses scaling an existing product, and larger organisations adding AI or new digital products. We work with teams in India and internationally.

Are the products on this site client work?

No. Everything shown is a concept product, prototype or internal product that we designed to demonstrate how we think and build. They are clearly labelled. We'll publish client case studies only with permission and real outcomes.

How do you price projects?

Discovery is a fixed-scope engagement. Build phases are priced either as fixed scope with milestones or as a monthly team, depending on how defined the scope is. You'll see an estimate broken down by phase before anything starts.

How quickly can we start?

Usually with a discovery call this week and a scoping workshop shortly after. Team start dates depend on current commitments; we'll be upfront about them.

Do you sign NDAs?

Yes, happily, before you share anything sensitive.

Who owns the intellectual property?

You do. Code, designs and documentation are assigned to you, and infrastructure is set up in your accounts.

Can you work with our in-house team?

Yes. We can lead, collaborate, or fill specific roles — and we document and hand over so your team can own it.

What happens after launch?

We offer ongoing product engineering, maintenance and SLA-backed support, or a structured handover to your team.

Have an idea? Let's build it.

Tell us what you're building. We'll come back with questions, a rough approach and how we'd scope a first version.
