Our story

From one sensor to a family of products.

Constellation Technologies started in 2016 with a single temperature-monitoring solution. Hospitals, pharmacies and research labs used it to keep vaccines, medicines and samples in range, and kitchens used it to keep food safe.

The platform grew around the people using it: digital HACCP checklists, cooldown tracking, menus and allergens, audits, claims and apps for residents and staff.

MeridianCT brings those products together under one name. Callisto is still Callisto, the product our customers know. What was Callisto Solutions is now MeridianCT, part of Constellation Technologies Ltd.
