📍 Boston, Massachusetts — area code 617
We build the software Boston runs on.
617SW is a software & app development studio crafting iOS and Android apps, .NET systems, and AI-powered workflow automation — for our own flagship products and for businesses that want theirs built right.
What we do
Four disciplines. One standard.
Whether it's a consumer app on the App Store or an internal system that runs your back office, we bring the same product-grade engineering to every build.
Why 617SW
Builders first, vendors second
We ship our own apps to the App Store and Google Play. That means when we build for you, you get a team that lives with the consequences of engineering decisions — not one that hands off and disappears.
We ship our own products
Our flagship apps live in the same stores yours will. We know what review, launch, and iteration actually take.
Local and accountable
Based in Boston. We meet in person across Greater Boston and Massachusetts — no offshore hand-offs, no time-zone roulette.
Business outcomes, not billable hours
Every engagement starts with the workflow or revenue problem, then works backward to the right amount of software.
