Custom mobile apps, AI-accelerated.
React Native iOS + Android, one codebase, ship in weeks not quarters. Senior US engineers using AI as accelerator on 25 years of production software experience. AWS Advanced Consulting Partner.
Expert team
25 years of enterprise mobile. AI as accelerator, not replacement.
40+ senior US engineers. 10+ years experience each. AWS Advanced Consulting Partner. Founder-led from Chicago. We use AI to ship faster — never to replace the engineering judgment that makes the difference between an app that works and an app that survives year 2.
The Mobile App Reality
You need a mobile app. The market wants to sell you a wrapper.
Half the mobile-app shops you've gotten quotes from are offshore body shops. The other half sell you 'low-code' tools that look like every other startup's app. Neither understands the backend integration work that turns a mobile app from a brochure into a real channel — auth, payments, CRM sync, push targeting, offline state. Caxy is engineers, not body shops or template-sellers. We use AI as an accelerator on top of 25 years of real mobile engineering. React Native means one codebase ships iOS + Android — usually 40% less than dual-native. Senior US team. AWS Advanced Consulting Partner. The same engineers who design your app are the ones who write the code and integrate with your backend. Most of our clients stay because we deliver, not because they're stuck.
“They’re the smartest group of people I’ve worked with; they can figure anything out. Caxy has respect for design. Other web firms often push back against designers if the designs don’t fit how they do things. By contrast, the Caxy team bends over backward to respect the original design concepts."
“They often go above and beyond to fully dig into a problem, identify solutions, and achieve our end goals. {...} We now can scale up our site and support future growth, thanks to Caxy Interactive’s efforts.”
“We feel like we’ve got a site that’s worth more than we paid for. The change that we were proposing from a redesign standpoint wasn’t going to be easy. So, he offered multiple times to come out and meet with many of those senior executives that have been with the company for 20 years.”
How a mobile app build works
Ship in weeks, owned by you.
Week 1-2: Discovery. We sit with your team, map the user flows, identify the integrations (auth, payments, CRM, data sync), and propose architecture. Output: fixed-price proposal.
Week 3-12: Build. React Native iOS + Android in one codebase. Your branding, your flows, your data. Integration layer for your existing backend systems. Admin console for your team. App Store + Play Store submission.
Ongoing: Support. iOS and Android OS updates each year. New feature rollouts. Performance + crash monitoring. Your team learns the codebase as we go — no handoff cliff.
Process Wins
A mobile app your customers actually use. iOS + Android in one codebase. Built around your real business systems — CRM, payments, loyalty, scheduling, whatever you operate on. Ships in months not quarters. Owned by you, extensible by your team.

Common questions
Questions we hear every week
01.
How much does custom software cost?
Most projects range from $150K to $500K depending on scope. Technology assessments start at $15K. Our blended rate is $200/hour including senior engineers, PM, and QA.
02.
How long does development take?
An MVP typically takes 6-10 weeks. Full enterprise platforms take 3-12 months. We build in two-week sprints with live demos every cycle so you see progress immediately.
03.
What happens if requirements change?
They always do. Our sprint model is designed for it. You see working software every two weeks and can adjust priorities in real time. No change orders for reasonable scope evolution.
04.
Do you work with our existing systems?
Yes. We frequently integrate with Salesforce, NetSuite, SAP, and custom databases. We also take over existing projects that stalled -- internal builds, offshore handoffs, failed vendor engagements.
05.
What technologies do you use?
Node.js, React, Scala, Python, AWS. Open source stack, no vendor lock-in. You own everything we build. AWS Advanced Partner.
