When you need custom software on AWS

Three moments when the software your business needs doesn't exist yet — we build it, ship it, and scale it.

Off-the-shelf software is bending your process

Generic SaaS forces your team into workarounds. Integrations pile up. The customer experience is shaped by the tool, not by you. We build custom applications around your actual workflow — cloud-native on AWS from day one, so the platform scales without the rewrite.

Your data and AI investments have no product surface

You've built pipelines, warehouses, or plugged into an AI provider — but your customers and operators can't touch any of it. We build the application layer that puts your data and AI in front of the people who'd use them, with authentication, permissions, and audit trails included.

Growth is exposing the limits of your current stack

Performance is degrading, bills are spiking, and your architecture wasn't designed for where the business has ended up. We re-architect to AWS-native patterns — serverless, containers, managed data services — and do it in phases that keep the business running while we work.

Stryde

Beta to Production in Under Twelve Weeks — on AWS Serverless

Stryde set out to build a connected fitness bike that gave customers real choice — workouts, instructors, and modes — without the walled-garden experience. They had the hardware team. They needed a software partner who could go from beta to production in under twelve weeks. We did, on AWS serverless.

How we build applications

1
Discover

Map users, workflows, and the systems this has to live inside. We write down what success means before we pick any AWS services.

2
Architect

Pick cloud-native patterns that fit the problem — serverless, containers, event-driven, relational or document. Infrastructure as code from the first commit.

3
Build in iterations

Short sprints, working demos, and your feedback on the real thing. Production-ready from the start, not a throwaway prototype followed by a rewrite.

4
Launch and run

Ship to production with observability, runbooks, and a plan for the next release. We can stay on as managed operations or hand the keys over clean.

Frequently Asked Questions

Every custom application is different, but we typically deliver working software within a few weeks, not months. The exact timeline depends on your specific requirements, complexity, and integrations, but we follow a clear, phased approach that keeps your project on track and minimizes delays. You’ll always have visibility into progress and timelines, with clear checkpoints to provide feedback along the way.

Absolutely! Most of our clients don’t have large technical teams—or any at all. Our approach ensures your custom application is easy to use and manage, even without dedicated IT staff. We provide thorough training and simple documentation, and we offer ongoing support plans to help manage updates, security, and maintenance as your business evolves.

Not necessarily. Custom software can often save money in the long term by eliminating the hidden costs of inefficiencies, manual tasks, and ongoing workarounds that drain your team’s productivity. Our approach is specifically designed for SMB budgets—delivering precisely what you need without overbuilding. You gain software that’s affordable, scalable, and built to deliver clear ROI from day one.

We develop a wide variety of custom applications tailored to your specific business needs. Our expertise includes:

  • Business applications that streamline internal workflows, automate processes, and integrate smoothly with your existing systems.
  • Consumer-facing applications that engage your customers directly, enhance their experience, and drive business growth.
  • Cloud-native applications leveraging AWS, enabling seamless scalability, security, and reliability.
  • Device and IoT applications connecting physical devices, sensors, and IoT hardware securely to cloud platforms, unlocking innovative, data-driven possibilities.

Whatever your vision, we have the expertise to deliver software tailored precisely for your business and your customers.

Yes! One of the greatest benefits of custom-built applications is flexibility. Unlike rigid off-the-shelf solutions, your app is built specifically around your workflows and can be adapted as your business changes. We build on scalable cloud technologies like AWS, ensuring your app grows and evolves smoothly alongside your business.
