Custom Software Development.
Senior engineers who design, build and maintain your software, onshore in Irvine. We stay on after launch, with fractional CTO leadership when you need it.
Senior engineers build it, and we stay on to maintain it.
Butterfli came to us after several development agencies had tried to build its platform and couldn't deliver it. Amira Learning brought us inside its team to ship the reporting its teachers needed. serviceMob had a prototype and needed it turned into a product its customers could use every day.
In each case the work started with understanding the business. Our senior engineers work out what the software has to do, build it to hold up in production, and stay on to maintain and extend it. When you also need technical leadership, a fractional CTO from our team can lead the work.
“In our experience, development partners often have strengths, but those positives are obfuscated by a fatal flaw. We've worked with teams that create quality code but are too expensive or too slow. We've found folks who are professional but struggle to grasp what we need. Finding a partner that delivers across the board has been a big advantage for us, and I'm very pleased to recommend VantaSoft to you.”

How We Work
Understand the Business
We learn what the software has to do for your business, your users and your team before we write code.
Design the Architecture
We choose the architecture and tools for your situation, so the software ships now and holds up as you grow.
Build and Ship
We build in short cycles with regular demos, so you see working software early and can steer as it takes shape.
Maintain and Extend
After launch we maintain the software, fix what breaks and build what comes next, or hand it to your team when you're ready.
Who This Is For
Prototypes That Need to Become Products
You have a prototype or a proven idea and need it built properly for real users. serviceMob came to us with a prototype, and we built the production platform.
Projects Others Couldn't Finish
A build has stalled or a vendor couldn't deliver. We take over, steady the codebase and ship it. That's how our work with Butterfli began.
Teams That Need Senior Engineers
Your team is good but stretched. Our engineers work inside it, on your codebase and to your milestones, the way we worked with Amira Learning for four years.
Software that lasts, and a team that stays.
Engineers who understand the business
Experienced engineers who learn the problem behind each feature, push back on requirements that won't work and catch issues before your users do.
Software that holds up in production
Tested and built for real users and real data, including regulated work like Butterfli's HIPAA-compliant platform.
A team that stays
We maintain and extend what we build. We've built and maintained Butterfli's platform since 2022.
Code your team can take over
Clear, documented code and architecture, so your own engineers can take it over whenever you're ready.
Related Work
