FAQ

Common questions.

How much does web application development cost in Helsinki?

LaunchCraft offers fixed pricing for all Helsinki projects. Landing pages start at $1,000, full MVPs from $3,500, and ongoing development at $2,000/month. You know the exact price before any code is written — no hourly billing, no surprise invoices.

How long does it take to build a web app developer project in Helsinki?

Most web application development projects ship in 4–6 weeks. Landing pages take 1–2 weeks. Complex applications can take up to 8 weeks. You’ll get an exact timeline during our scoping call, and I’ve never missed a deadline across 20+ shipped products.

Do you work with Helsinki clients remotely?

Yes. I work with clients worldwide, including many in Helsinki. Communication is async-first via Slack or Telegram with daily updates. You’ll always know exactly where your project stands.

Why hire LaunchCraft instead of a Helsinki agency?

Helsinki agencies charge $30K–$100K and assign junior developers to your project. With LaunchCraft, you get one senior full-stack developer at a fraction of the cost. Same or better quality, shipped faster, with 100% code ownership.
