Stop paying monthly for software that doesn't fit your business
Every month, companies spend thousands on SaaS subscriptions for tools that almost do what they need. They pay per seat, per user, per feature. They work around limitations instead of solving the actual problem.
Custom software changes that math. You pay once to build exactly what your business needs. You own the code. You control the roadmap. And you stop sending monthly checks to someone else’s platform.
We have been building custom software for nearly 25 years. Our clients include Fortune 500 companies like Ford, Verizon, and Intel alongside funded startups and mid-market firms. We build web applications, mobile apps, geospatial tools, AR/VR experiences, and enterprise integrations.
The result is software that fits your business like a glove, not a one-size-fits-all tool that you have to reshape your workflow around.
Enterprise Web Platform
A legacy tracking system was costing the team hours of manual work every day. We built a custom web application with real-time shipment visibility that replaced three separate SaaS tools and cut customer support volume significantly.
AI Powered Mobile App
Performance Golf needed a mobile coaching app that combined video analysis with AI recommendations. Off the shelf tools could not handle the custom AI pipeline. We built a native app from scratch that now serves thousands of active users across iOS and Android.
GPS Operations Platform
Flagger Force manages thousands of daily field operations. No existing SaaS tool could handle their dispatch, GPS tracking, and reporting requirements in one system. We built a custom platform that gave dispatchers real-time visibility and eliminated manual status calls.
Custom software is not for everyone. If a SaaS tool does exactly what you need at a price you can live with, use it. But if any of these sound familiar, it might be time to build your own.
If you are not sure whether custom or SaaS is the right move, that is exactly what our free consultation is for. We will run the numbers with you and give you an honest recommendation.
From concept to production in weeks, not months. We build responsive web applications with React, Angular, Node.js, Python, and .NET. Our web projects have served millions of users for companies like Ernst and Young and Shipment Trackers. You get scalable architecture, clean code, and a team that handles deployment and maintenance.
Your existing tools should not require manual data entry to share information. We build custom APIs and integration layers that connect your CRM, ERP, field tools, and databases into one system. Intel, Aramark, and Asplundh trust us to keep their data flowing.
This is where Seisan stands apart. We have 25 years of experience building geospatial tools, augmented reality experiences, and virtual reality applications. From fleet tracking dashboards to Apple Vision Pro experiences, we build spatial software that most agencies cannot.
Your software keeps getting better after launch. We provide maintenance, performance optimization, and feature updates on a flexible support plan. When your business changes, your software evolves with it. You are never locked into a rigid contract.
We have built custom software for companies in retail, automotive, telecom, healthcare, defense, education, and professional services. Here is what that looks like in practice.
Custom Tools for Taco Bell, Home Depot, and Popeyes
We have built trade show activations, sales enablement tools, and customer engagement platforms for some of the biggest consumer brands in the country. These are not template websites. They are custom applications designed to capture leads, drive sales, and deliver measurable ROI at events and in-store environments.
Business Impact: Every activation is tied to pipeline metrics. Leads are captured, synced to CRM, and tracked through to conversion.
Field Operations Software for Ford and Asplundh
When your business operates in the field, off the shelf software does not cut it. We build custom geospatial and mobile tools for companies that manage fleets, field crews, and mobile workforces. Real-time GPS tracking, offline-capable apps, and dashboards that give managers full visibility.
Business Impact: Dispatch teams operate with real-time data. Manual processes are replaced with automated tracking and reporting.
Enterprise Platforms for Verizon and Intel
Fortune 500 companies come to us when they need custom software that meets enterprise security, compliance, and scalability requirements. We build platforms that handle millions of transactions, integrate with legacy systems, and pass the security reviews that off the shelf tools cannot.
Business Impact: Enterprise clients get software that scales with their business instead of limiting it. Total cost of ownership drops as SaaS subscriptions are consolidated.
Mission Critical Applications for Penn State Health and DHS
Healthcare and government organizations have strict compliance requirements that most SaaS platforms cannot meet out of the box. We build custom applications that meet HIPAA, FedRAMP, and agency-specific security standards. Every line of code is documented, tested, and auditable.
Business Impact: Compliance is built in from day one. Audit timelines shrink because documentation is thorough and architecture is transparent.
Most projects range from $50,000 to $500,000+ depending on complexity. A focused web application might cost $50K to $150K. A full enterprise platform with integrations, mobile apps, and ongoing support will cost more. We scope every project up front with a detailed estimate before any development begins.
A typical project takes 3 to 9 months from discovery to launch. Smaller applications can ship in 8 to 12 weeks. Larger enterprise projects with multiple integrations take longer. We build in two week sprints so you see progress continuously and can adjust priorities along the way.
Custom software makes sense when your annual SaaS spend exceeds the one-time cost of building, when no existing tool fits your workflow without heavy workarounds, or when you need to own your data and intellectual property. We will help you run the numbers during a free consultation.
Yes. When we build software for you, you own 100% of the source code and intellectual property. It is your asset. You can host it wherever you want, modify it with your own team, or bring in any other vendor. There is no lock-in.
Every project starts with a discovery phase where we define requirements, map risks, and create a detailed scope document. Then we design and prototype before writing production code. Development happens in two week sprints with regular demos. We handle deployment, testing, and handoff when the product is ready.
They always do, and that is fine. Our sprint-based process is designed for flexibility. You review working software every two weeks and can reprioritize features as you learn more. We document change requests, assess impact on timeline and budget, and keep you informed every step of the way.
We offer flexible support plans for maintenance, bug fixes, performance optimization, and new feature development. Most clients stay with us on a monthly retainer because we already understand their systems. But there is no long-term contract required.
Start with a free consultation. We will review your current tools, understand your pain points, and give you an honest assessment. Sometimes we recommend SaaS. Sometimes we recommend a phased approach where you start small and scale. The consultation costs nothing and there is no sales pressure.
Tell us about your project. We will schedule a free 30 minute call to discuss your goals, review your current tools, and determine if custom software is the right investment for your business. No obligation. No pitch deck. Just a conversation about what you need.
