Each one an operating system for an industry that never had one — familiar by design, so the software just makes sense.

Openings span the General Operating Systems studio and its companies.
We’re always glad to meet people who think in systems. Tell us what you’d build.
General Operating Systems is a venture studio building a family of companies, each designed like an operating system for its industry: familiar by design, so the software just makes sense.
It’s built by me, Jason Mackey. I start companies from the operational problems I keep running into, then design each one around a paradigm people already understand — the desktop, the file, the app — so the software feels obvious from the first click.
Every company here shares that idea. The goal is simple: software that works the way you already think.
Tell us what you’d build, or just say hello.

Vintrak is the system of record for the vehicles people care about — one platform, two products: one for the collectors who own them, one for the dealers who trade them.
The system of record for private collections — inventory, maintenance history, documents, and provenance, all in one living record.
Extends the platform to the businesses that buy and sell — inventory, listings, sales, and back-office operations for independent and specialist dealers.
FirstCloze is the operational backbone to launch and run a fund. Formation, closing, LP management, and back office live together, instead of scattered across lawyers, spreadsheets, and inboxes.
First-time managers spend too much of their first fund on operations. FirstCloze gives them the infrastructure a large firm would have on day one — so their time goes to investing, not administration.
Munin is the intelligence layer for local government. It gathers the agendas, budgets, permits, and public records that cities run on and turns them into one clear, searchable operating picture.
Public information is public in name only when it’s buried in PDFs and portals. Munin structures and surfaces it, so municipal teams — and the people they serve — can finally see what’s happening in one place.
