Where execution
still breaks down

  1. Problem

    Vibe-coded MVPs that look identical to every other AI app

    Implication

    Users feel it. Trust drops. Retention drops.

  2. Problem

    AI tools that produce one screen at a time

    Implication

    Products that work but don't guide users anywhere

  3. Problem

    Agencies that bill hours, not outcomes

    Implication

    You pay whether the work ships or not

  4. Problem

    In-house dev teams stuck in the backlog

    Implication

    Features pile up. Roadmap slips. Founders firefight

Case studies

F.A.Q.

Who is this for?
B2B SaaS founders, CTOs, and product leaders who want senior strategy and design, and want code shipped without committing to a retainer or hiring more developers.
How is this different from hiring an agency?
Agencies bill hours. Magic Team bills only the code that ships into your repo. If a change doesn't land, you don't pay for it. Plus every change goes through senior human review. No AI-slop, no rubber-stamping.
How is this different from vibe-coding with Cursor or v0?
Vibe-coding tools generate one screen at a time and assume you have senior eyes on the output. Magic Team is a managed workflow. Agents draft, our senior developers review architecture and edge cases, and only reviewed changes reach your repo.
What does it cost?
€199/month base subscription with flexible credits. Then you pay only for code that ships. No retainer, no minimum hours, no long-term contract.
Can you also handle strategy and design?
Yes. Software development pairs naturally with our Product Design and Product Management services. Senior humans plan and design; managed agents do the heavy lifting.
What does the onboarding look like?
No 1-hour kickoff call. You sign up, connect your repo, and answer onboarding questions through a simple chat-like interface. AI agent and senior humans walk you through goals, users, and current product. You answer at your pace.
What if we already have an in-house dev team?
Magic Team plugs in alongside. Agents handle the backlog you can't get to; your team focuses on the high-judgement work. Reviews and approvals stay with you.
