    At a glance

    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 →

    Our process

    How does our process work?

    1. 01

      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.

    2. 02

      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.

    3. 03

      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.

    4. 04

      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.

    5. 05

      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.

    FAQ

    Frequently Asked Questions

    It varies widely based on complexity. An MVP might start around $15k-$30k, while complex enterprise systems can go higher. We provide detailed, transparent quotes after our initial discovery.

    Yes. Once the project is paid for, you own 100% of the Intellectual Property (IP) and source code.

    We use modern, reliable technologies like React, Angular, Vue for front-end; Node.js, Python (Django/Flask), .NET Core for back-end; and AWS/Azure/Google Cloud for infrastructure.

    Yes. We can take over existing codebases for maintenance, bug fixing, and feature additions, provided the code is in a manageable state (we'll audit it first).

    A typical MVP takes 3-4 months. Larger enterprise systems can take 6-12 months. We work in 2-week sprints so you see progress constantly.

    Absolutely. We offer flexible maintenance packages to handle updates, security patches, and server monitoring post-launch.

    Ready-made software ("COTS") is cheaper initially but often inflexible. Custom software is a long-term asset that maps exactly to your unique workflows, provides a competitive edge, and eliminates license fees. You own the IP, meaning no vendor lock-in.

    Data migration is a critical risk we manage carefully. We perform a full audit of your legacy data, map it to the new schema, clean it, and write automated scripts to transfer it securely. We verify data integrity at every step.

    We use battle-tested, enterprise-grade technologies. On the backend, we typically use .NET Core, Node.js, or Java. For the frontend, React or Angular. We use PostgreSQL or SQL Server for data, and deploy on AWS or Azure.

    Yes, extensively. We act as your "Fractional CTO." We explain complex technical concepts in plain English, guide you through feature prioritization, and ensure you make informed decisions about your product's future.

    We design for scale from Day One. We use Microservices architecture where appropriate, allowing different parts of the app to scale independently. We use caching (Redis), CDNs, and load balancers to ensure the system can handle growth from 100 to 1,000,000 users.

    That is the beauty of Agile. We expect requirements to change. We can swap out features in the next sprint backlog. If a change significantly affects budget or timeline, we discuss it transparently before proceeding.
