How quickly can you start?
Usually within one to two weeks of signing. Discovery workshops can start sooner, often within a few days of our first call.
Do you work with clients outside India?
Yes. We are remote-first and work with clients in the US, UK, Europe, the Middle East and Australia, with planned daily overlap in your working hours.
Who will actually work on our project?
Senior engineers, including the founders. We introduce the team before kick-off and you talk to them directly throughout the project.
How do you protect our idea and code?
We sign an NDA before detailed discussions. Code lives in your repositories, access follows least privilege, and all IP is assigned to you in the contract.
How do you estimate cost?
After a short discovery call we share a written estimate with ranges, assumptions and risks. For fixed-price work the price is locked once the scope is agreed.
What happens after launch?
We offer maintenance and support plans covering monitoring, security updates, bug fixes and continuous improvement. You can also take the code in-house with a full handover.
