Everything a growing product needs, under one roof.
We work end to end, or slot into the part of the process where you need us most.
Web Design & Development
Marketing sites and web apps built for speed, clarity, and conversion — from the first pixel to production.
Product Engineering
Full-stack SaaS and internal tools, taken from prototype to a production system your team can rely on.
UI/UX Design
Interfaces that are simple to use and hard to forget, grounded in real research rather than trends.
E-commerce
Storefronts that load fast and sell faster, with checkout flows tuned for real conversion data.
Brand & Identity
Logos, design systems, and a visual language flexible enough to scale with your next five launches.
Support & Maintenance
Ongoing care after launch: performance budgets, security patches, and new features as you grow.
A few products we've helped ship.
Case studies below are placeholders — swap them for your own once your first projects land.
Orbital Finance
A real-time investing dashboard with sub-second data refresh and a design system built for trust.
Verdant & Co.
A DTC storefront for sustainable home goods, rebuilt for a 2.1s to 0.6s load time and a 34% lift in conversion.
Northwind Analytics
A data platform for logistics teams — from onboarding flow to the charting engine that powers daily decisions.
Lumen Health
A booking and intake experience for a telehealth network, designed to feel calm during a stressful moment.
Atlas Robotics
A product site for an industrial robotics company, with a 3D configurator that turned spec sheets into a story.
Fable Coffee
A brand-first storefront with a headless CMS, so the marketing team ships new drops without waiting on engineering.
A process built to remove surprises.
Four stages, the same team throughout, and a working build in your hands early.
Discover
A short, focused workshop to learn the business, the users, and what success actually looks like.
Design
Wireframes into high-fidelity UI, reviewed together at every stage — no surprise reveals.
Develop
Clean, tested, documented code on a modern stack, built to be handed off or maintained by us.
Deploy & Grow
Launch, monitor real usage, and iterate — most engagements continue past the first release.

What it's like to work with us.
“Zennex took a rough idea and shipped a product our users actually love. Fast, sharp, and easy to work with from day one.”
Priya Nandakumar
Founder, Orbital Finance
“They rebuilt our entire storefront in under six weeks and it outperformed the old one on every metric we track.”
Daniel Cho
Head of Growth, Verdant & Co.
“What stood out was the communication. We always knew exactly what was being built and why.”
Marisol Reyes
COO, Northwind Analytics
A small team, built to move like one.
Zennex is a studio of engineers and designers who partner with startups and growing businesses to design, build, and ship digital products worth talking about. No account managers, no handoffs — the people who plan the work are the people who build it.
Speed
Working builds within the first week, not the first month.
Craft
Details reviewed at the pixel and the millisecond level.
Partnership
You always know what's being built, and why.
