No traction against established competitors. ## What we can do for you End-to-end MVP design and development support for early-stage SaaS ### Product strategy & discovery Define your value prop, validate core assumptions, and identify your ideal customer and use cases. ### UX/UI design & prototyping Wireframes, high-fidelity UI, interactive prototypes.

[Book a Discovery Call](https://donux.com/contact-us) ## What you get Everything you need to move from idea to launch-ready MVP. - Product strategy and user research summary. - Figma design files. Wireframes, high-fidelity UI, interactive prototypes. - Lightweight design system with components, typography, color, and patterns. - Onboarding flow and first-use experience. - Design handoff documentation, including UX copy guidelines. - Post-launch iteration plan based on analytics and user feedback. ## Before you start. ### Can you help validate our product idea before we build? Yes. That's what the Discovery & Strategy phase does. We interview users, validate assumptions, and prototype core flows. We often uncover major pivots, saving months of development. ### Do you build the product or just design it? Both. We design it, and through Magic Team we can also build it end-to-end. Otherwise, we partner with your dev team or recommend developers we trust. Our handoff is detailed and developer-friendly so your team executes faster. ### How do we stay aligned during the project? Weekly check-ins, live co-design sessions, shared Figma, dedicated Slack channel. You see work in progress, give feedback, we iterate. ### What if we need to pivot during the MVP phase? It happens. That's why discovery and prototyping are critical. Better to pivot on sketches than deployed code. Our process embraces iteration and fast failure. ### Do you help with go-to-market or just the product? Product design is our core. We help with positioning, messaging, and launch narrative. We don't craft the full GTM strategy. ### Can I build my MVP 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 designers and developers. ## See the work. Selected product design projects.
