PartyOS wasn't born in an office. It was born at a club door, at two in the morning.

Before we built software, we took people to parties. With RJFIESTAS, our party agency in Rio, we have spent more than 7 years taking tourists and locals to the best nights in the city. Every week we worked with different guest lists, promoters, doors and producers, and we saw the same chaos everywhere: guest lists over WhatsApp, spreadsheets that never added up, duplicate names at the door, promoters arguing over who brought whom, and the night’s money counted by hand after the sun was already up.

We looked for a tool that would fix it and couldn't find one. Ticketing platforms sold the ticket and their job ended there. The list, the promoters, the door and the numbers were still our problem.

So we built it. First for the parties we work with. Then for everyone's.

That's how PartyOS was born: a platform made by people who live the night, to handle everything that happens before, during and after every event.

Part of Grupo Hommel

PartyOS is part of Grupo Hommel, a group that creates and connects companies: RJFIESTAS (party agency in Rio), MØL TURISMO (tourism and experiences in Brazil), RJEMBARCAÇÕES (boat experiences in Rio) and PartyOS (event technology). Independent brands, one ecosystem. What we learn in one, we bring to the others.

Made at night. Built for the door.
