Why Mejix
Building a digital product is harder than it looks. Most projects don't fail because of a bad idea — they fail because of poor scope definition, under-resourced teams, missed handoffs between design and engineering, or a lack of delivery accountability. A dedicated product development partner doesn't just write code. They own the outcome.
You need this service if:
You know what you want to build but don't have the designers, engineers, and PMs in-house to do it. Hiring takes too long and costs too much for a single product build.
Your engineers are tied up on existing products. You need a separate team to run a new build in parallel — one that can move fast without pulling people off current work.
You've been through agency relationships where the product arrived late, over budget, or not what was scoped. You need a partner whose default is delivery, not excuses.
Design, frontend, backend, mobile, QA, infrastructure — your product needs all of it, and managing five separate specialists or agencies is creating coordination overhead that slows everything down.
How do we solve
We cover the full product development lifecycle — strategy, design, engineering, QA, and launch — with a single team accountable for the whole thing.
We start every engagement with a structured discovery — defining the product vision, user stories, feature scope, and technical requirements before a single line of code is written.
Our designers build wireframes, user flows, and high-fidelity interfaces that are validated before development starts — so engineering time isn't spent building the wrong thing.
Web, mobile, API, backend — we build across the full stack using modern, maintainable technology. React, React Native, Node.js, Supabase, and more depending on what your product needs.
Native iOS and Android, or cross-platform React Native — we build mobile products that perform, scale, and pass app store review. Yehuda's AI app and NES are live examples.
Every feature is tested before it ships. We run functional, integration, and performance testing as part of every sprint — not as an afterthought at the end of the project.
We don't hand over a zip file and disappear. We manage the launch, monitor performance, fix post-launch issues, and provide a stabilization period before transitioning to your team or ongoing support.
Obsessed with delivery. Every project, every time.
Key benefits
Design, engineering, QA, and PM in a single team under one engagement. No handoffs between agencies, no finger-pointing when something doesn't work — one partner owns the outcome.
We run 2-week sprints with demos at the end of every cycle. You see working software regularly, not a big reveal at the end of a 6-month engagement.
We use AI at every stage — planning, code generation, QA, and documentation — to deliver faster without cutting quality. The same engineering standards, at a better pace.
Every product we build is documented, tested, and structured so your team can take it over confidently. We build for the long term, not just the launch day.
The process
A structured process that runs from the first conversation to the moment your product is live — and beyond.
We map your product goals, user needs, and technical requirements. We define what we're building, what it needs to do, and what success looks like — before any design or code begins.
Wireframes, user flows, and high-fidelity UI designs are built and reviewed before development starts. You approve the design before we build it — no surprises mid-sprint.
We define the technical architecture — database schema, API structure, infrastructure, and third-party integrations — and document it clearly before development starts.
We build in 2-week sprints, with a demo at the end of every cycle. You see working software throughout the build, not just at the end. Progress is visible and trackable.
QA runs in parallel with development, not after it. Every feature is tested functionally and on real devices before it ships to production.
We manage the deployment, monitor the first days live, fix any post-launch issues, and provide full documentation and handover training. The product is yours — we make sure you can run it.
Certifications & Recognitions














Our work
We built a custom AI-powered mobile app for Yehuda that automates diamond detection — reducing manual grading time and increasing throughput. The app reached and diagnosed over 5,000 patients from launch.
We delivered end-to-end product development for NES — an AI-native platform built from the ground up by the Mejix team. Designed, engineered, tested, and launched.
We built the GiftCrowd product from concept to launch — a group gifting platform that handles collections, contributions, and fulfillment in one seamless experience.
Reviews & Certifications

Mejix has successfully created and launched a functional mobile app, which allows the client to reach and diagnose over 5,000 patients. Despite geographically dispersed clients, the team is accommodating and communicative. They've worked hard to deliver the project on time and within the budget.
