BigGuardian® offers an innovative temperature control system specifically designed for cattle management. The core product is the Guardian device, a small thermometer that can be easily implanted in cattle—vaginally for females and ruminally for males.

This system continuously monitors the animals' temperature and transmits data to a centralized software system via a gateway installed at the farm. The primary use case for BigGuardian is to detect health anomalies early, thereby preventing disease outbreaks and optimizing treatment costs. This technology serves a diverse client base including cattle farmers and veterinary professionals across various geographical markets, with a focus on regions that prioritize advanced agricultural practices and livestock welfare. BigGuardian operates on a flexible revenue model, where clients are charged only for the animals being monitored on a daily basis, disregarding the number of Guardian devices installed.

This subscription-based approach allows farmers to manage costs effectively while benefiting from precise health monitoring. Revenue is derived from the ongoing service of monitoring, which includes daily alerts and customized treatment recommendations based on data analysis conducted by veterinary algorithms. This model ensures that farmers can access technology without an initial investment, thereby streamlining their operations and enhancing the health of their livestock. In January 2026, BigGuardian raised EUR 1.

5 mn in venture funding led by Swanlaab Venture Factory, with participation from Aval CLM. The company will utilize the funding to improve its platform’s production costs, strengthen its commercial structure, expand into strategic markets, advance its technology, and deploy its system at scale on cattle and swine farms. BigGuardian is focused on developing new products and enhancing its existing offerings, with plans to enter new geographical regions in the near future.
