The cost of
an overloaded dev team

  1. Problem

    Hiring senior developers takes months.

    Implication

    Roadmap stalls. Sales promises age into customer frustration.

  2. Problem

    Your dev team covers too much at once.

    Implication

    Quality drops. Bugs and tech debt pile up.

  3. Problem

    AI tools generate code one screen at a time.

    Implication

    Output looks fast, integration debt piles up.

  4. Problem

    Agencies bill hours regardless of what ships.

    Implication

    You pay for delays, not delivery.

Connect your repo

1. Connect your repo

Sign up, connect GitHub or GitLab, point us at the codebase. We index it. No kickoff call needed.

Drop a request and scope

2. Drop a request

Describe the feature, fix, or improvement in plain language. The platform proposes scope, acceptance criteria, and effort. You approve.

Build and senior review

3. Agents build, seniors review

Managed agents draft the implementation. Senior developers review architecture, tests, and edge cases.

Live preview and decision

4. Live preview, you decide

Click through the working result on a preview environment. Approve, request changes, or reject.

Your needs change? Scale capacity up or down month-to-month. No contract locks.

Case studies

F.A.Q.

Who is this for?
B2B SaaS founders, CTOs, and engineering leaders with a roadmap that outpaces team capacity. Teams that want to ship more without hiring or signing a retainer.
How is this different from hiring a contractor or agency?
Contractors and agencies bill hours. Magic Team bills only the code that ships. Every change goes through senior human review before it reaches your branch.
What if we only need extra capacity part-time?
That works. Pay-as-you-ship plus a base subscription means you scale up or down month-to-month. No long-term contracts.
How do you handle our existing codebase and conventions?
The platform indexes your repo and follows your existing patterns. Senior reviewers enforce architecture and style consistency before merge.
What if we don't approve a change?
You don't pay for it. Pay-per-ship means rejected or paused work costs nothing. The base subscription covers platform access and senior capacity.
Can we keep our in-house team?
Yes. Magic Team plugs in alongside. Agents handle the backlog you can't get to. Your team focuses on the high-judgement work.
Can I get product design and strategy too?
Yes. Software development pairs naturally with our Product Design and Product Management services. Senior humans plan and design; managed agents do the heavy lifting.
