Vaccines have to be refrigerated. Successful delivery depends on an uninterrupted “cold chain.” Nexleaf have made a system that deploys cheap and reliable GSM-based sensors - and the associated data analytics - that makes sure that failing refrigerators are detected and fixed fast. Revolutions in mobile and sensor technology have opened up a host of new possibilities for monitoring, along with action feedback loops, to ensure that devices are maintained and used well. Nexleaf’s sensors and data services now drive rapid impact at scale - their facilities protect vaccine supply for 1 in 10 babies born on Earth.
