Overview
Off-the-shelf software is built for the masses, not for your unique competitive advantage. When your business processes outgrow generic tools, Ortem Technologies steps in. We are a US-based custom software development company that has delivered 1,000+ custom applications since 2012 for startups, growth-stage businesses, and enterprise organizations across healthcare, fintech, logistics, retail, and professional services.
Custom software development is the right choice when you need to automate a process that does not fit a template, when off-the-shelf tools are creating integration debt, or when your competitive moat depends on software that your competitors cannot simply purchase. We build bespoke mobile applications, enterprise web platforms, SaaS products, internal tooling, and API layers that connect your existing systems.
What we build: Legacy system modernization (moving monolithic .NET or Java applications to cloud-native microservices without data loss or downtime). Custom ERP and CRM modules that integrate with your existing Salesforce, HubSpot, or QuickBooks setup. HIPAA and GDPR-compliant applications for regulated industries. Marketplace platforms with complex transaction logic. Internal operations software that replaces spreadsheets and disconnected tools.
Our technology stack: .NET Core and Node.js for high-performance backends. React and Vue for dynamic frontends. PostgreSQL and MongoDB for data persistence. AWS, Azure, and GCP for cloud infrastructure. Each stack decision is made based on your specific performance, scalability, and compliance requirements — not defaults.
How we work: Every engagement starts with a discovery phase (2–4 weeks depending on complexity) where we define requirements, make architecture decisions, and produce a specification you review and approve before development begins. Development follows a sprint cadence with weekly demos. You own the code from day one — no vendor lock-in, no licensing fees, just software built for your business.
Typical timelines and costs: A custom internal tool or MVP runs $15,000–$50,000 over 6–12 weeks. A mid-complexity web application or mobile app runs $50,000–$150,000 over 3–6 months. A full SaaS platform or enterprise system runs $150,000–$500,000+ over 5–12 months. All quotes are fixed-price after discovery. See our full cost breakdown →
Our 98% client retention rate and 300+ client relationships across the USA, UK, Australia, and the Middle East reflect the quality and reliability of what we build. See our case studies →

How We Work
Discovery & Solution Architecting
We start with a deep dive into your business workflows. Our architects design a system blueprint that solves your specific pain points, defining technical specs and success metrics.
MVP & Prototyping
We believe in validating ideas fast. We build a Minimum Viable Product (MVP) or clickable prototype to test core features with real users before committing to full-scale development.
Agile Implementation
We work in 2-week sprints, delivering shippable code updates regularly. This protects you from "scope creep" and ensures the final product matches your evolving needs.
Testing & Security
Our QA team performs rigorous regression testing, load testing, and security audits to ensure the software is bug-free and hacker-proof before going live.
Support & Evolution
After deployment, we provide SLAs for critical support and continue to iterate on the product, adding new features based on user feedback and market changes.
