Process
Four steps. Scope and price are fixed in writing before any work starts.
Message us
Write in Telegram or WhatsApp: what you need and by when. We reply with clarifying questions.
Scope and fixed price in writing
We agree in writing on what gets built, what it costs and how the work is split into stages.
Build with regular demos
You see working results at every stage, not only at the end.
Launch and support
We launch, hand over the code and all access, and stay available for fixes and updates.
Stack
Who owns the code?
You do. At the end we hand over the repository, the deployment and all access. Nothing stays tied to us.
Will you sign an NDA?
Yes, on request, before you share any details.
How do we communicate?
In Telegram or WhatsApp, directly with the developer building your project. Calls when needed.
How does pricing work?
We scope the project first, then fix the price and stages in writing. The price changes only if the scope does, and only with your approval.
Do you support the project after launch?
Yes. We fix issues and make updates after launch. Ongoing support can be agreed separately.
Can I see references?
Yes. Reviews and completed projects are public on the founder’s Freelancehunt profile. On a call we can walk you through similar work.
