Common Questions
The 5 things every new client asks before they start working with us.
Yes — we sign a mutual NDA before any project discussion begins. All code, designs, business logic, and data you share with us stay strictly confidential. We've maintained this policy with every client since 2018.
We work IST (GMT+5:30) from our Gandhinagar office. In practice this means 3–5 hours of overlap with UK/Europe mornings, 4–5 hours with Australian mornings, and same-day turnaround with US clients on the East Coast. Our team is flexible and adjusts for important meetings or sprint reviews.
You do — 100%. All code is committed directly to your repository from day one. All intellectual property, designs, databases, and infrastructure belong to you. We use no proprietary frameworks or tools that create a dependency on us. If you ever want to move on, you take everything with you.
We work in your tools, not ours. Most clients use Slack or Teams for daily communication, Jira or Linear for sprint tracking, and Google Meet or Zoom for weekly calls. You get a dedicated project manager as your single point of contact — no hunting through a team to find out what's going on.
Most projects kick off within 1–2 weeks of signing. We use that time for discovery, environment setup, and onboarding your team. For urgent projects, we can often start sooner — book a call and we'll tell you exactly what's possible for your timeline.
Share your idea with us. We'll turn it into a world-class digital product on time, every time.
