The cost of
an overloaded dev team

ProblemImplication

Hiring takes months.

The roadmap stalls.

Your developers cover too much.

Quality drops and tech debt piles up.

No one specializes in SaaS architecture, integrations, billing flows.

Product quality drops, shipping slows, and reliability suffers.

What we can do for you

Flexible dev support that works inside your team, tools, and roadmap

Embedded software development

Developers join your Slack, rituals, and sprint cadence. Work moves with your team.

Features, integrations, and APIs

From spec to deployed PR. Wired into your auth, data model, and existing architecture.

Flexible monthly capacity

Scale dev support up or down based on roadmap and launches.

Fast onboarding & clear handoff

We ramp fast, document work properly, and help your team keep momentum without adding process overhead.

Working with Donux enabled us to iterate much faster, and as a result, we increased the adoption of a key product feature from 17% to 66%.

How we extend your dev team in 5 steps

From discovery to shipping real code in three weeks.

  1. Discovery

    We audit your codebase, meet your team, and understand your constraints.

  2. Onboarding

    Developers dive into your repo, conventions, and architecture docs.

  3. Integration

    We plug into your standups and sprint planning. We start shipping work on week 3.

  4. Collaboration

    Async PRs and updates. Weekly syncs. We flag issues early and suggest solutions.

  5. Scale & Adjust

    Your needs change? We add or reduce capacity. No contract locks. Month-to-month flexibility.

Before you start.

How is Donux different from hiring a freelancer?

Freelancers lack team context and accountability. Our developers integrate into your workflow, learn your product deeply, and operate as part of your team. You also get access to our full team for specialized needs like design, product management, and strategy.

What if we only need dev support part-time?

That works. We structure engagements based on actual needs.

How long before your team is productive?

A first conversation defines the relevant scope, dependencies and investment. For an existing product transformation, we confirm what fits the 90-day delivery window before kickoff. A focused supporting engagement is scoped separately.

Can you work in our existing tools (GitHub, Linear, Slack)?

Yes. We use your tools, follow your processes, and join your Slack workspace.

What happens if we need to pause or scale down?

You adjust capacity month-to-month. No long-term lock-in.

How do you handle communication across time zones?

We're flexible on time zones. We make sure to overlap for real-time collaboration. Async PRs and documentation keep your team unblocked when we're offline.

Can I extend my team through Magic Team?

Yes. Magic Team is a managed team of AI agents and senior humans that ships real code. Connect your repo and get features, MVPs, or bug fixes delivered as PRs, reviewed by Donux senior developers and designers.
