Users, features, screens, integrations, risks, team and timeline — the same first pass our product leads do on a call. Built with the kind of AI we build for clients.

Don't include personal or confidential details.
Try one:

Add a senior team that works like your own — engineers, QA, DevOps and design — in your time zone, with your tools, and with the code always in your repositories.

See it before you pay for it

Watch your team take shape.

From a rough sketch to production — you see and try every stage, not just the invoice.

We map your idea into screens and flows on day one.

Show, don't tell

The kind of products our team builds — as concepts

Real interface work, drawn as working UI. These are concept products — labelled honestly — so you can judge our design and engineering before you talk to us.

Sound familiar?

We built this company around what goes wrong.

Most people who contact us have been burned before. Here's what usually went wrong — and what we do instead.

The problem

“Hiring senior engineers is taking months.”

How we handle it

A vetted team you interview and approve, working in your codebase within weeks.

The problem

“Our last outsourced team went quiet for weeks.”

How we handle it

Your standups, your board, a tech lead accountable and a written update every Friday.

The problem

“Time zones meant we only heard from them at night.”

How we handle it

A daily overlap window in your working hours for standups and reviews.

The problem

“We got a quote, but no idea what's actually in it.”

How we handle it

A written scope that lists every screen, feature and integration, with a cost range — before you pay for any build work.

The problem

“The agency kept the code. We couldn't leave.”

How we handle it

Code in your GitHub, infrastructure and store accounts in your name, IP assigned in the contract. Leave any time with everything.

Promises we put in writing

Seniority mix

Senior-heavy teams cost more per month and usually less per feature.

03

Skills

Specialist skills like AI, native mobile or DevOps.

04

Time-zone overlap

How many hours of overlap you need each day.

05

Duration

Longer engagements allow better planning and continuity.

06

Management

Self-managed team with a lead vs. engineers inside your management.

FAQ

Questions teams ask first.

Can we interview the engineers?

Yes — you meet and approve everyone who joins your team, and you can ask for a change at any time.

How quickly can a team start?

Usually within a couple of weeks of agreeing the roles, depending on the skills and seniority you need.

Who manages the team?

Your choice: they can work inside your management, or a tech lead from our side owns delivery and reports to you.

What happens after I submit an enquiry?

A product lead reads it and replies within one business day with a few questions. Then a 30-minute call, then a written scope with a first-version plan and a cost range. No commitment until you say yes.

You're based in India. How does that work across time zones?

We keep a daily overlap window in your working hours — US, UK, Europe or India — for calls and standups, and work asynchronously the rest of the day, so you wake up to progress. You get a shared board, a weekly written update and a demo every two weeks.

Who owns the code and IP?

You do. IP is assigned to you in the contract, the code lives in your GitHub, and infrastructure is created in your cloud and store accounts from day one.

Will you sign an NDA?

Yes — before you share anything sensitive. Just ask on the first call.

Can you work with our existing team?

Yes. We can own a whole product, take one part of it (mobile, AI, backend), or add engineers to your team with your tools and rituals.

Do you support the product after launch?

Yes. Most clients keep us on a monthly plan for monitoring, fixes and new features. If you'd rather run it in-house, we hand over documentation and runbooks.

How do contracts and payments work?

Discovery is a small fixed-scope engagement. The build is either fixed scope with milestone payments or a monthly team. Invoices in USD or INR.

Are the products on this page your client work?

No. They're concept products our team designed and built as UI to show how we think. We label them clearly, and we don't publish client names or numbers without permission.

Need more engineering capacity? Tell us who you need.

No commitment, no pressure. Here's exactly what happens after you send it:

  1. Within 1 business dayA product lead (not sales) reads your note and replies with questions.
  2. Free 30-minute callWe talk goals, users and budget. NDA first if you like.
  3. Written scope & estimateFeatures, timeline and a cost range — yours to keep.
