Websites, apps & AI,
built to grow your business.
One studio. Four disciplines. Premium engineering, end to end.
Premium digital systems,
built end to end.
Four disciplines, one studio, one standard of execution. Each engagement is shaped around the outcome — never templated, never outsourced, never rushed.
Web Development
Marketing sites, e-commerce, and full platforms built on Next.js and TypeScript. Fast, accessible, and engineered to outlast the trends that built them.
Mobile Apps
iOS and Android products from a single React Native codebase. Native performance, App Store ready, and built to scale beyond a launch sprint.
AI Integration
Claude, OpenAI, and custom agents woven into real workflows. Practical automation with cost controls — leverage where your team needs it, not novelty.
Marketing & Ads
Meta, TikTok, and Google campaigns with conversion tracking from day one. Measured growth tied to real outcomes, never to vanity metrics.
A studio, not
a factory.
ONYX Solution is an independent digital studio building software for businesses that want to grow. Premium engineering, clear strategy, and the same hands from discovery through launch.
We build digital products
Websites, mobile apps, and AI systems for businesses that want to grow. Four disciplines under one studio, designed and engineered end to end.
We work with founders directly
No account managers, no offshore handoffs, no junior teams. The same hands that pitch the work do the work — from first call to final deploy.
Clarity first
Plain language, written scopes, fixed prices. You will never have to decode a proposal or wonder what something costs.
Quality over volume
We take on fewer projects so each one receives the attention real work requires. A crowded studio is a rushed studio.
Boring tech on purpose
We choose tools that will still be here in five years. Longevity beats novelty — your product should outlast its frameworks.
You own everything
Code, accounts, domains, credentials. No vendor lock-in, no exit fees, no leverage games if you ever want to move on.
A clear path,
from idea to launch.
Four stages. Written into every engagement, regardless of size or scope. You always know what's happening, what's next, and what it costs.
Discovery
A working session — not a sales call. We map the problem, the constraint, and the smallest version worth shipping.
Strategy & Scope
A written proposal with clear scope, timeline, and a fixed price. No retainers, no surprise invoices, nothing buried in a contract.
Design & Build
Production-grade work shipped against a staging URL you can watch evolve. Daily updates, weekly check-ins, and zero black boxes.
Launch & Care
We deploy, hand over every credential, and stay close after launch. Bugs fixed in hours, not weeks — and always by the team that built it.
Ready to build something that lasts?
Every engagement starts with a conversation. Share your vision, your constraints, and your timeline — we'll respond with a clear path forward and a scope in writing. No forms, no runaround, no sales theatre.
