Train by Cell is a cloud-based platform that uses text messaging and mobile web authoring to boost employee engagement in training.

The platform aims to solve problems with low email open rates and content not being accessed by bringing training and communications to employees on their mobile devices using short, bite-sized interactions. It has over 1,500 clients worldwide across various industries.
