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 each of 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 portfolio of companies, each one the operating system for its industry. The aim is simple: help established industries operate with greater efficiency.
I’m Jason Mackey. I start these companies from the operational problems I keep running into, then build each one around the way people in that industry already work. The software is familiar by design, so it makes sense from day one and starts paying off quickly.
Every company here shares that idea: software that helps an industry run better, and that works the way you already think.
Tell us what you’d build, or just say hello. Every message reaches a person, not a queue.
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.
