CELSI - Revolutionising Temperature monitoring
Start up Overview
Unlike traditional systems that record temperatures every 20 to 40 minutes, Celsi’s sensors measure temperature every second and aggregate data every minute, allowing businesses to detect fluctuations instantly. This technology has been widely adopted, with major clients like Yo-chi, a leading frozen yogurt chain in Australia, already implementing Celsi’s solution across 43 locations.

Albert Jindra
Albert, originally from the Czech Republic, pursued a master’s degree in chemistry before transitioning into programming. After moving to Australia 25 years ago, he explored various roles in programming and desktop publishing before launching Celsi.
The idea was born when he helped a local butcher struggling with unreliable temperature monitoring solutions. Determined to find a better way, he tested multiple sensors for over a year, ultimately refining the technology that now powers Celsi.


A glimpse into the future
Celsi is on the verge of redefining how industries manage temperature, with bold expansion plans into healthcare, pharmaceuticals, and research. As innovation accelerates and new partnerships take shape, Celsi is shaping a future where environmental control is smarter, faster, and absolutely reliable.
