FAQ
Questions buyers ask us first
What is AI-accelerated development?
Our engineers use AI tools to draft code, tests and documentation, then review and own every change themselves. Repetitive work goes faster, so a smaller team covers more of your roadmap. Architecture, security and code review stay with people.
How do we get started?
Talk to an expert on a free 30-minute call about your goals, budget and timeline. We reply within one business day and send a written estimate once we understand your scope.
What does the 1-week free trial include?
A free week with a dedicated team on your real work, under NDA and on a defined scope. If it is not the right fit, we replace the engineer at no cost. We agree the details on the call.
Is our code safe when you use AI tools?
Your NDA applies to all our work, including work where we use AI tools. Our engineers review and own every change. The code is yours from day one. If you have rules about which AI tools may be used on your code, we follow them.
Do you sign an NDA?
Yes, from the very first meeting. We sign your NDA or ours before you share any details about your project.
Who owns the source code?
You do. The code is yours from day one.
Will your team work during our business hours?
Yes. We agree overlapping working hours with every client, wherever you are in the world. Our engineers shift their day so there is a daily window for calls and work continues outside it.
Can your developers join our in-house team?
Yes. With a dedicated team, our developers work in your tools and join your stand-ups.
