CUSTOM SOFTWARE DEVELOPMENT
Custom enterprise software development services by engineers whose careers were spent designing and accrediting complex platforms for defense and intelligence.
Clever, tenacious, precise.
Advanced capabilities in expert hands
Forged by securing classified systems.
Matched to your work – owns the results
Service-Disabled Veteran-Owned
WHAT YOU END UP WITH
The software, the architecture, the security posture, the delivery pipeline — all built to satisfy accreditation by design.
Designed to satisfy FedRAMP, CMMC, or your specific compliance framework from the architecture phase — not retrofitted at the end.
Threat modeling, SBOM generation, secure-by-default selection, and continuous security analysis — all decided in the architecture phase.
Modular components on open standards across advanced mobile apps, web apps, desktop applications, and containerized distributed systems. No vendor-proprietary lock-in.
Security gates at every commit. Predictable, traceable releases with observability instrumentation already in place.
ENGAGEMENT SCOPE
A custom software build is a focused engineering engagement that produces a complete, compliance-capable system ready to deploy. Below is what goes into producing it.
HOW WE DO THE WORK
Our founders built and accredited complex software and systems inside defense and intelligence — more of them, faster, than almost anyone. That rigor carries over by default: security and compliance are pushed all the way left in the timeline, with threat modeling at the architecture phase, continuous security analysis, and compliance artifacts written as the code is written — not reverse-engineered at the end.
HOW IT RUNS
Every engagement runs through the same five phases in the same order.
A discovery conversation tailors the engagement to your specific situation. You see what’s involved and roughly how long it will take before any work starts.
A Principal Investigator is matched to your engagement based on domain expertise relevant to your industry and operation. Kickoff brings the PI, your stakeholders, and the engagement plan together. The PI runs the engagement from kickoff through handoff.
Engineering build runs in milestone-driven phases. The PI directs application code development, automated testing, and threat modeling throughout, with security and compliance documentation written as the code is written. Milestone reviews bring your stakeholders into the work at agreed checkpoints, and any scope changes are flagged and priced before they happen.
Deployment and acceptance testing run with your stakeholders. The build is verified against the originally agreed requirements; any issues are captured for resolution before final handoff.
Acceptance feedback is incorporated. The complete package is delivered: source code, the compliance documentation mapped to your framework, and the operations documentation.
THE DEPTH
If you know this field, you will recognize these names. If you don’t, we’ll walk through it on the discovery call.
PUBLISHED WORK
Write-ups of actual engagements — what we were hired to do, what we actually did, and what changed.

A premium med spa needed to escape vendor lock-in, rebuild their entire web presence in three weeks, and begin building toward HIPAA compliance. One PI owned every line of effort — from the emergency rewrite through the first compliance milestone.

S5T mapped the engineering gaps in Alessa’s aging cloud infrastructure, drove the multitenant modernization plan, and built the internal capability for Alessa engineers to own and operate the architecture going forward.
QUESTIONS YOU'RE PROBABLY ASKING
Your Principal Investigator, plus specialists from our bench where the work requires them. No junior-only teams, no offshore handoff. The PI is responsible for the architecture and the quality of everything that ships.
We find that we work best with clients that are looking for a full-service provider who handles technical execution and technical project management for them, so that they can focus on their core business. Said more plainly, we do not embed our technical staff with our clients', or work under our clients' technical project management.
You do, by default. IP ownership terms are in writing before work starts. No ambiguity.
Post-launch support is a separate engagement, scoped and priced independently. The build engagement ends with a clean handoff and complete documentation.
Depends on the environment. For FedRAMP, CMMC, FIPS, RMF, and HIPAA environments specifically, our engineers have direct accreditation experience.
Yes. AWS GovCloud and Azure Government. We've deployed into both.
In general, we do not work this way – though it does happen in very specific circumstances. We work best with clients that have requirements that we can craft a solution to, and then deliver that solution end to end within our own teams.
HOW WE STAFF IT
Most retainers put a seasoned name on the pitch and a junior hand on the work. We don’t. A Principal Investigator — a working expert matched to your situation — owns the engagement from kickoff to reporting.
They have the technical depth to do the work themselves, and they command a small network of specialists who come in when needed. They are not a project manager. They are not an account manager. They are the person whose name is on the work.
Who a PI is not:
WHO WE SERVE
If you see yourself below, a discovery conversation is worth your time.
THE GROWTH-STAGE OWNER
You run a successful small business in a regulated industry— a med spa group, a legal practice, a financial services firm. You’ve outgrown the patchwork of tools and part-time vendors that got you here. Now you want seasoned expertise. Someone that has built real systems and sophisticated marketing plans. Someone who will learn how your business operates and use holistic tech and marketing approaches to support your growth.
THE COMPLIANCE-BOUND TECHNICAL BUYER
You’re a Director, VP, or CTO at a company whose software has to satisfy FedRAMP, CMMC, HIPAA, or some other complex regulation. You’ve been burned by vendors who claimed compliance fluency and couldn’t perform. You want a team whose founders actually shipped advanced accredited systems, and who can walk your auditors through the work and achieve favorable outcomes.
THE MISSION OWNER
You’re a program manager, contracting officer, or technical lead inside DoD, the IC, or other heavily compliance-bound agency. You need contractors who deliver on time, own their deliverables, and have a history of building and successfully accrediting advanced software and cloud systems. Our founders have done exactly that.
