06Case study · Youzem

Client film · 2 min

Two agencies had failed. We shipped in 3 months.

Scroll to open

David, founder of Youzem

2 failures. 3 months. 1 app in the stores.

“When we saw the first version, smooth and bug-free, we said: we have the right people.”

fundraising in progress

David had to prove his concept to investors. After two failed attempts he needed a team that ships. Weekly sprints, a demo every week, a direct line to the developers.

Read the case study
  1. 01

    “We worked with two companies that were supposed to be competent. They could not make the project happen.”

  2. 02

    “From the first conversations I knew this was the right team: frankness, a shared vision, availability at any hour.”

07Method

Five steps. No surprises.

  1. 01 · Day 1 · 30 min

    We listen

    One call. Your project, goals and constraints. We tell you frankly whether we are the right team.

  2. 02 · Day 2 · 24 h

    We scope

    Specifications, key modules, architecture, risk areas. In writing.

  3. 03 · Day 3 · 48 h

    We show

    A clickable prototype and a final quote per module. You see the product before you pay for the product.

  4. 04 · Weeks 1-2

    We build

    One-week sprints. A demo every week. You change priorities whenever you want.

  5. 05 · Weeks 3-6 and after

    We launch, we stay

    Production release, training, maintenance. The code and the access are 100% yours.

You know what happens, when, and what it costs. Before you sign.

08Team

A team that cares about your project.

CaptainDev co-founders Mouad and Hamza are your direct contacts. Together with 20+ developers, designers and project managers, they turn your priorities into a useful product. You work with the people building it, from the first call to launch.

11FAQ

The questions we get.

How long does a digital project take?

A first version can be delivered quickly when the scope is clear. A complete website, platform or application usually takes several weeks depending on approvals, content, integrations and functional complexity.

Can I see examples of your work?

Yes. We can share web, mobile, platform, internal-tool and data-focused projects relevant to your project scope.

How do you guarantee code quality?

We apply best practices: functional scoping, adapted architecture, code reviews, tests when the scope calls for them, continuous integration, documentation and handover. The goal is to deliver a maintainable product, not just a first version.

What happens after launch?

We can support maintenance, fixes, improvements, optimisation, documentation and team training. For corporate websites, this can also include editorial support and CMS onboarding.

What happens during the first consultation?

It is simple: a 30-minute call to understand your project, goals and constraints. Then we send a detailed quote within 24h with roadmap, timeline and budget. No commitment.
