About Callimacus
At Callimacus, we're working to change how people interact on the web. For the past 30 years, the user experience as we know it has been anchored to a typographic paradigm — predefined navigation trees of pages, sections, and menus — established in the Nineties when the web was born.
As the way people get informed, entertained, and shop evolves, traditional websites and interfaces are losing relevance, and the tools available limit the creative evolution of digital experiences. Callimacus was born from the conviction that the whole web experience can and should be reinvented.
So we built the engine for a different kind of digital experience. Callimacus is a multi-agentic platform that plugs into a company's existing stack and reads multi-dimensional signals to understand what a visitor wants in the moment. Then, in milliseconds, our proprietary technology composes the entire interface around that intent, selecting the most relevant content and components as the person interacts.
Callimacus was founded in 2024 with the early backing of Brunello Cucinelli — one of our first investors, and now one of our customers. We launched in January 2026 to strong organic interest from enterprise customers, and recently raised from Salesforce Ventures the largest AI investment they have made in Italy, and one of their most significant in Europe.
We are a small, product-focused, founder-led team. We work on hard problems that haven't been solved before — by us or anyone else — and the people who join now get to solve them. We move fast, with high agency and strong ownership.
What you'll build
You'll join a small senior team at the point where the platform's foundations are still being set. Callimacus is in production with demanding customers, and the architecture, the performance envelope, and the shape of the developer experience are all still yours to influence. Decisions you make in your first months will still be load-bearing in three years.
