We build, secure, and run the systems enterprises depend on
Winmill brings software engineering, cybersecurity, AI, and cloud operations together as one partner. Founded in New York City in 1994, we’re trusted by 44 of the Fortune 100, and 97% of our clients stay with us year after year.
Big enough for enterprise work, small enough to know your name
Today our work centers on AI and Azure. We build modern applications, move enterprises to the cloud, test and defend systems against real-world attacks, and run critical infrastructure, including our own eMembership platform.
Our clients are concentrated in financial services, healthcare and medical devices, benefit funds and labor organizations, education, government, and media. Many of those unions and benefit funds also use eMembership, our membership management software. One thing hasn’t changed since 1994: we transfer knowledge as we work, so your team gets stronger while the project moves forward.
Built around short cycles and honest conversations
Software evolves, so we don’t disappear for six months and return with a big reveal. Every engagement runs as a series of short sprints, frequent reviews, and incremental releases.
Small steps, visible progress
We validate early, adapt quickly, and ship in increments, so you see working software throughout the engagement instead of waiting for the end.
Straight talk
You get honest answers about scope, risk, and cost, and if something goes off track, you hear it from us first. We’d rather have a hard conversation than a surprised client.
Leave it better
We call it stewardship: leaving everything better than we found it, from the comments in the code to helping with an overnight deployment that wasn’t in the plan.
