Expert team
Senior US engineers, AWS Partner, 25 years of production SaaS.
40+ senior engineers across Chicago, Austin, Denver, Detroit, Milwaukee. Every engineer 10+ years experience. AWS Advanced Consulting Partner. We're not a body shop — average team tenure 5+ years. The architects who design your SaaS write its code and support it in production.
The Scale Problem
Your SaaS MVP shipped. Now scale is breaking it.
Most SaaS development shops are great at MVP and terrible at scale. They build for the demo, not for year 2. The multi-tenant architecture has shortcuts that work at 50 customers and explode at 500. The database schema assumes one customer at a time. The deployment pipeline can't handle parallel rollouts. By the time you hit traction, the original dev shop has moved on and your engineering team is rebuilding what should have been built right the first time. We architect SaaS for the scale you'll actually hit. Multi-tenant data isolation done correctly. AWS infrastructure that scales horizontally. Deployment pipelines that ship per-tenant rollouts safely. The senior engineers who design it stay through production hardening — so when scale hits, the system bends instead of breaking.
“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 SaaS dev works
From MVP to production scale.
Phase 1 (4-8 weeks): Architecture sprint — multi-tenant model, data isolation, infrastructure plan, scaling thresholds. Phase 2 (8-16 weeks): MVP build with the production architecture baked in (not bolted on later). Phase 3 (ongoing): Production hardening, performance optimization, and scaling support as your customer base grows. The same senior engineers stay through all three phases.
Process Wins
A SaaS product that handles 10x scale without re-architecture, ships features in days instead of months, and lets your team focus on customer value instead of firefighting database problems. Built to be owned by your engineering team — not abandoned by ours.

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.
