About
Our startup consists of three people. Arcarius was founded by Isis and Robin in November 2024 – accompanied by many weekend and evening hours, as we were both working full-time jobs. In June, Thomas entered the picture, rich in experience, ideas, and courage, and a wonderful addition on a personal level. His investment enabled us to focus entirely on Arcarius.
It all started with the chat function in One-on-One. The idea was to build a chattable database for accounting data – simply out of curiosity. Naturally, it didn't stop there.
Very soon it became a challenge for us – how can we design an agent that is reliable enough for an industry that lives for the accuracy of the second decimal place, while also offering the user maximum flexibility (and even a bit of joy)? And, as a side note: what do people actually need?
We were incredibly fortunate to be able to talk with amazing people from the industry who encouraged us and pointed us in the right direction. Driven by our passion for building and the brilliant ideas of brilliant people, we decided to get serious and go all-in.
It is our ambition to develop Arcarius far beyond what is already possible today. For that, we need you: your ideas, your concerns, your feedback.
It would be our pleasure if you joined us on this journey.
