Our approach
At TopDevs we think along with you, not just build what you ask.
Your sparring partner, from first idea to long after launch.
We go for the 10
Not for the 7.
We think along
Listen first, then honest advice.
A clear plan
You know where you stand.
After launch too
We keep building your growth.
What we automate
Custom AI
Your knowledge. On tap with AI
Put your company's knowledge behind a chat your team already uses. Private, searchable, and built on your data only.
AI Assistant on Telegram & WhatsApp
Your team asks in the apps they already use and gets answers in seconds. No new tool to learn.
Vector Database & Semantic Search
Search by meaning, not exact words. Find the right document even when the keywords don't match.
RAG over your own data
Answers come from your files, with a source for every reply. It admits what it doesn't know.

Questions we hear the most
What does a project cost?
Every project is a fixed price agreed up front, no open-ended hourly billing. After a short, no-obligation intake we send you a blueprint and quote: a clear plan of exactly what we'll build and why, with the full price, so you know everything before we start.
How long until it's live?
Most projects go from first call to a working prototype in days, and to a finished product in weeks, not months. We work in fast iterations so you see progress the whole way.
Do I really own the code?
Yes. You get 100% ownership of the code we write. No lock-in and no licensing games, hosting with us is always optional.
What if I want to change it later?
The code is yours, documented and built on modern, standard tech, so any developer can pick it up and extend it. We're happy to keep improving it, but you're never tied to us.
What happens after delivery?
We hand over the code, documentation and access, and stay available for support, maintenance or new features on your terms. Optional hosting and monitoring keep everything running smoothly.
