What clients say after launch
“Working with Tjvex Studio felt like adding a senior product team overnight. They shipped our Flutter app ahead of schedule.”
“They took a rough idea and turned it into a product our users love. Communication was sharp, delivery was on time, and the backend has been rock solid.”
“The AI assistant they built handles our bookings and FAQs around the clock. Our front desk finally gets to focus on patients instead of phone calls.”

How much does a project cost?
Every project gets a fixed quote in US dollars before work starts. As a guide, a focused MVP starts around $4,500, a mobile app around $6,000 and an AI call assistant around $2,500. The pricing page lists a starting price for each service.
How long does it take?
A focused MVP usually launches in six to ten weeks. Larger platforms ship in phases, so you are using real software early. AI assistants are often live within two to four weeks.
Can you train an AI on our own data?
Yes. We prepare your documents, tickets and databases, ground a model on them, add guardrails and testing, and deploy it privately in your cloud or on your own servers. You own the result.
What does an AI call assistant do?
It answers calls in natural speech, books and reschedules appointments, takes orders, answers questions from your knowledge base, updates your CRM and transfers to a person when needed, at any hour and in several languages.
We are in Europe or the Gulf. How do we work together?
Most of our clients are. We overlap with European and Gulf working hours, hold weekly demo calls, write everything down in English and invoice in US dollars. We sign an NDA before you share anything sensitive.
Who owns the code and the AI?
You do. Source code, designs, cloud accounts, trained models and documentation are transferred to you, with no lock-in.
