[Build with us](https://donux.com/contact-us) [![4Dem email marketing platform](https://images.app.donux.com/unsafe/case-studies/4dem/vYp6OEMLVThoCZ2ADTOyaUUUcBw.png)](https://donux.com/case-studies/4dem) Selected product design work[4Dem](https://donux.com/case-studies/4dem) [**4.9/5** on Clutch 9 client reviews](https://clutch.co/profile/donux#reviews) Selected product design clients - 4DEM - Fluida - La Marzocco - Blue.ai ## Building got faster. Shipping didn't. ProblemImplication ### AI agents shipping unreviewed code One bad merge wipes a database or ships a liability ### 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 [Our work with 4Dem](https://donux.com/case-studies/4dem) ## From idea to shipped code in 5 steps 1. ### Discovery call We learn your product, stack, and backlog. We define scope and identify the highest-leverage work to ship first. 2. ### Scoping & estimate We map out the feature set, break it into shippable units, and give you a fixed cost per deliverable before work starts. 3. ### Development Agents do the heavy lifting. Senior developers architect, review every change, and keep the codebase clean. 4. ### Live preview & review You click through a working build before anything merges. Feedback goes in, changes come back fast. 5. ### Ship & iterate Approved changes merge to your branch. We track what shipped and queue the next round.

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. ## See the work. Selected product design projects.
