An app, a tool,
an AI agent that works

iOS · Android · Back-office · Automations.

Design + code. Same studio, same person.

This one, we designed and coded it.

· FAQ
How much does a mobile app cost?

Design starts at €990 excl. VAT. For a full app (design + code + stores), the price depends on scope: you receive a detailed quote within 24h after a 20-minute call, free and no commitment.

What is an AI agent, concretely?

A program plugged into your existing tools (email, calendar, CRM, Notion, Slack) that runs tasks defined with you: answering inbound requests, qualifying leads, preparing quotes, chasing unpaid invoices. You decide what it's allowed to do, and you stay in control.

What are the timelines?

A testable mobile-app MVP usually takes 6 to 8 weeks. An internal tool or an AI agent is often faster. The precise schedule is laid out in the quote, milestone by milestone.

Who designs and who codes?

The same person: Ramsi Ferkous, designer and developer, 12 years of production execution (BNP Paribas, MAAF, AFPA, Novabank). No intermediary, no loss between the mockup and the code.
