Working with us from the USA, UK, Canada, or Australia?
We are built for international collaboration. Our team operates with flexible overlap hours to accommodate US and UK business hours, and our entire workflow is designed around async-first communication — so timezone is never a barrier to great work.
Flexible overlap hours
We accommodate morning slots for UK/EU clients and afternoon overlap for US/Canada clients. You always have a time to talk.

Frequently Asked Questions (FAQ)
What actually happens if the project goes wrong - and what is your accountability?
Honestly? Every software project hits obstacles. Scope changes, technical surprises, third-party API issues, something always comes up. Here is what we commit to: weekly demo calls so you see real progress, never just promises. Milestone-based payments so you never pay for work that isn't done. A written scope document you approve before we build a single screen. And if we make a mistake - we fix it at our cost, not yours. We've never left a client project unfinished. You can verify that by speaking to any of our past clients directly - we'll connect you.
If we part ways, can another developer understand and continue the codebase you built?
Yes, and we design for this from day one. Every project includes inline code documentation, a README for every repository, and a technical handover document on completion. We follow industry-standard conventions for React Native, Flutter, and Node.js so any competent developer can pick up the code without our involvement. We actually encourage clients to have their own developers review our code mid-project. If it doesn't pass their review, we fix it before the next milestone payment is released.
Who actually builds our product and will the people we meet be the people doing the work?
The founders - Sagar and Hiten - are involved in every project from scoping to delivery. We are not a large agency that hands your work to a junior team after the sales call. Your project is reviewed, architected, and overseen by the same people you speak to. We are a focused team by design, we take fewer projects to do better work. If you ever feel the quality or attention isn't what we promised, you have the founder's direct contact and the right to call that out immediately.
We are based in the USA / UK — will the timezone difference actually cause problems?
Honestly, timezone is only a problem if communication is chaotic. Ours is not. Here is exactly how we handle it: for US clients, we hold a standing weekly call at 8–10am EST. For UK clients, we overlap from 12pm–3pm GMT. Every working day you receive an async update - what was built, what is next, what needs your input via Slack or Notion, so you wake up informed without needing a call. We use Loom video walkthroughs for complex updates so you can watch the progress on your schedule. We have never had a client tell us timezone was a problem past the first week.
How do you handle scope changes - and can the price increase after we agree on a number?
Our fixed-scope projects have a fixed price - period. If we miss something in our scoping that is our error to fix at no additional cost. If you request something genuinely new beyond the agreed scope, we raise a separate change order with a clear cost and timeline before doing any work. You will never receive a surprise invoice. The only way costs change is if you choose to change them and you approve every change order in writing before we proceed. This is not standard in the industry. We make it standard for every client.
Do you just build what we ask or do you push back when something won't work?
We push back - respectfully and with reasoning. If you ask us to build a feature that we believe will hurt your user experience or add unnecessary technical complexity, we will tell you clearly, explain why, and suggest an alternative. You are always the final decision-maker. But our job is to protect your product's quality, not just execute instructions. Some clients find this uncomfortable at first. Every single one of them has thanked us for it by the time the project launches.
What happens after launch, if something breaks at 2am our time, what do we do?
Every project includes a 60-day post-launch support period at no additional cost. Any bug or issue that is a result of our development is fixed for free, with a maximum 24-hour response time. For critical production outages, we have an emergency contact channel that gets a response within 4 hours regardless of timezone. After the 60-day window, we offer structured monthly maintenance packages so you always have someone accountable for your product's health. You will never be left alone with a broken app and no one to call.
