Walk the workflow.
We shadow the people who'll use the system, read the data, and surface the unstated rules. Output is a written scope you can hand to your CFO.

Software, live and
Software, live and
built to last.
For thirty years, TStream has designed, shipped, and maintained custom systems for teams who can't afford software that ages poorly. Independently owned in Michigan; engineered to outlast the trend cycle.
Six practices, one engineering team.
Every engagement is scoped, built, and maintained by the same people. No outsourcing, no offshore handoff, no surprise handover at cutover.
01 · Custom Software
Explore
Fit-for-purpose systems, built to order.
When off-the-shelf costs more to work around than to replace, we design and build software that matches your process exactly — and stays maintainable as it grows.
02 · Modular
Explore
Reusable by design.
A curated library of hardened building blocks that compose cleanly across your portfolio.
05 · Real-Time
Live data,
Explore
Live data,
low latency.
SignalR, WebSockets, and streaming pipelines for dashboards, trading, and monitoring systems that can't afford page-refresh latency.
03 · Portals
Explore
Client, staff & partner platforms.
Role-aware portals with auth, audit, and the workflows your business runs on.
04 · Communications
Explore
Messaging that integrates.
Email, SMS, chat, and transactional flows wired to the rest of the stack.
06 · AI / Machine Learning
Explore Practical intelligence, without the hype.
LLM integrations, classification pipelines, and retrieval systems grounded in production-grade infrastructure. We deploy what works; we don't ship demos.
Since 1995
Thirty years of shipping software that still runs.
We started on Windows NT and we're still here — through five platform shifts, three cloud migrations, and more framework fashions than anyone wants to count. Longevity is a product decision.

A short, honest process.
Three stages, each with explicit exit criteria. No surprise invoices, no death-march sprints, no deliverables hiding behind vocabulary.
Ship small, ship true.
Short, reviewable increments. You see the system working end-to-end early; we harden and extend from there. The code is yours; we don't ransom it.
Stay on as long as needed.
After launch we stay on as long as you need us. Some of our longest-running engagements started in the Clinton administration.
