What We Build
We design and develop custom software tailored to your business — from a simple, single-purpose website to a distributed, enterprise-scale platform. Whatever the scale, we scope the requirements, architect the system, build it, test it, and deliver it. Not sure where to start? We'll help you find the right path.
Web Applications
Browser-based applications that run anywhere with an internet connection. From SaaS platforms to internal dashboards, we build responsive, scalable web apps with modern frameworks.

Native and cross-platform apps for iOS and Android. Built for performance and designed for how people actually use their phones — on the go, with one hand, in seconds.
Best for: Field teams, customer engagement, on-the-go workflowsDesktop Applications
Powerful, native desktop software for Windows and macOS. When you need deep OS integration, offline capability, or heavy-duty processing that the browser can't match.

Multi-service architectures built to scale — API platforms, system integrations, and distributed infrastructure engineered for reliability under real production load.

That's exactly what we're here for. We'll evaluate your needs, your users, and your constraints — then recommend the right platform and approach. No commitment, just clarity.

Based in Sioux Falls, South Dakota, SimmTech Software was founded by a software engineer with 30 years of hands-on experience across every phase of the development lifecycle — requirements, architecture, design, engineering, testing, and delivery. We've served as system architect, software architect, software engineer, and DevOps provider on projects ranging from single-purpose websites to distributed, enterprise-scale platforms and infrastructure.
We've built software across manufacturing, distribution, vertical market platforms, and financial services. That breadth means we understand your domain, not just your tech stack. Whether it's a small business tool or an enterprise system, when we build, we build to last.
Serving Sioux Falls, Eastern South Dakota, and Beyond
We work with businesses in Sioux Falls and nearby communities, including Tea, Harrisburg, Renner, Crooks, Worthing, and Brookings. Local or remote, you work directly with an experienced software engineer from discovery through delivery. And if you're outside the area, that's not a problem — most software work can be done remotely, so we're happy to partner with businesses anywhere.
