Atelier Lumen
"We used to juggle a spreadsheet for cash, another tool for invoices, and a shared drive for contracts. StartupOS didn’t make things ‘magical’ — it just made them consistent. That’s what we needed."
Italy
Studio Nord
"The biggest change for us was visibility. Invoices, contacts, and support history are tied together, so we don’t waste time asking ‘what happened with this client?’ every week."
Germany
Weber Digital
"I’m picky about security hygiene. Having a proper secrets workflow with access controls and an audit trail removed a lot of uncomfortable ‘who has the key?’ moments."
Portugal
Maré Labs
"We’re a small team, so context switching hurts. StartupOS helped us centralize the operational stuff — especially treasury and invoices — without adding another layer of process."
Portugal
Ribeira Studio
"The flat pricing is honestly what made us try it. Once we onboarded everyone, the real win was onboarding: docs, credentials, and customer context are no longer spread across five places."
Poland
Northbridge Ops
"We don’t need a hundred features — we need fewer loose ends. The modules feel opinionated in a good way: clear statuses, clear ownership, and fewer follow‑ups."
