Let's discuss your projectHow Youzem launched its app in 3 months
From idea to the App Store: the story of David, founder of Youzem
“We worked with two companies that were supposed to be competent, but they could not make the project happen. With CaptainDev, we finally found a team that listens, understands the vision and brings real solutions.”
“From the first conversations, I knew this was the right team: frankness, sincerity, a shared vision and above all availability at any time.”
“When we saw the first version, smooth and bug-free, we said: “We have the right people.” You made us forget two failed attempts and thousands of euros lost.”
Application preview
The challenge
Youzem needed to prove the viability of its concept to investors and early users through a stable, smooth and attractive mobile app. After two failed attempts and tens of thousands of euros lost, David needed a reliable and involved technical team.
Our solution
We developed a complete mobile application through weekly agile sprints, with a demo every week and direct communication between David and our team.
Key features:
- Authentication & user profiles
- Video/photo challenges and activity feed
- Votes, comments and real-time ranking
- Push notifications and analytics
- Complete back office and secure AWS hosting

Frequently asked questions
Everything you need to know before starting
What is the minimum budget for a web, mobile or data project?
Our projects usually start from EUR 5,000 for a defined scope. The budget depends on deliverable type, content volume, features, integrations, design level and expected timeline. The estimator helps qualify the need quickly.
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 present web, mobile, platform, business-tool and data-heavy references. During our first conversation, we can select the cases closest to your specifications.
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 handle maintenance, fixes, improvements, optimization, documentation and team training. For institutional websites, this also includes 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.
