AI agents shipping unreviewed code
One bad merge wipes a database or ships a liability
Software Development for B2B SaaS
Software development at lightning speed
Senior humans plan and review. Managed AI agents do the heavy lifting. You see every change running before you accept it. Pay only for code that ships.
Build with us
Building got faster.
Shipping didn't.
ProblemImplication
Agencies that bill hours, not outcomes
You pay whether the work ships or not
In-house dev teams stuck in the backlog
Features pile up. Roadmap slips.
What we can do for you
From a fresh MVP to bug fixes and security patches on a live product.
Build a new product
Scaffold and deploy an MVP from zero. From idea to production code in about a week.
Ship new features faster
Your team stays focused on the roadmap. We build the features that keep piling up alongside them.
Fix bugs at scale
Agents scan your codebase to flag bugs and performance bottlenecks. Senior review before any fix ships.
Security review
Find vulnerabilities before someone else does. Agents scan, seniors verify, you decide what to patch.
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%.
Mario CTO @ 4Dem
From idea to shipped code in 5 steps
Discovery call
We learn your product, stack, and backlog. We define scope and identify the highest-leverage work to ship first.
Scoping & estimate
We map out the feature set, break it into shippable units, and give you a fixed cost per deliverable before work starts.
Development
Agents do the heavy lifting. Senior developers architect, review every change, and keep the codebase clean.
Live preview & review
You click through a working build before anything merges. Feedback goes in, changes come back fast.
Ship & iterate
Book a Discovery CallApproved changes merge to your branch. We track what shipped and queue the next round.
What you get
A managed development workflow that bills only when code ships.
Senior human review on every change before it reaches your branch
Live preview environment per feature
Pay-as-you-ship pricing.
Every change lands in your repo. You own the code.
Where we can help
Before you start.
Who is this for?
B2B SaaS founders, CTOs, and product leads who need code shipped without hiring more developers or committing to an agency retainer.
How is this different from a traditional agency?
Agencies bill hours whether or not the work ships. We bill only for code that lands in your repo. If a change doesn't make it through review, you don't pay for it.
How is this different from vibe-coding with Cursor or v0?
Vibe-coding tools hand the output straight to you with no review layer. We use managed agents and senior developers who check every change for architecture, edge cases, and security before it reaches your branch.
Do I need to connect my existing repo?
Yes, we work inside your existing GitHub or GitLab repo. If you're starting from scratch, we can scaffold one for you as part of the discovery call.
What does the discovery call cover?
We learn your product, current stack, and the highest-leverage work to tackle first. You'll leave with a scope breakdown and a fixed cost per deliverable before any work starts.
What if we already have an in-house dev team?
We work alongside them. Your team keeps ownership of the high-judgement calls. We absorb the backlog that keeps slipping. Reviews and merges stay with you.
Who owns the code?
You do. The code lives in your repo from the moment it ships. No lock-in, no licensing strings.
Can you also handle design and product strategy?
Yes. Software development pairs naturally with our Product Design and Product Management services if you need the full loop covered.
