I used to work with the Lesson.ly team. New and existing employee training is a big problem space with lots of room for innovation. Many employers want to do a better job of training their employees, but most don't have a systematic way of doing so.
For example, a support team might need continual training of the product(s) they're supporting. Or a sales team needs to get up-to-speed on how to use sales software. Or a distributed workforce needs to learn about company benefits and policies.
In many cases, employers turn to team meetings, email, powerpoints, pdf's, etc. Some will implement a bulky LMS (learning management software, usually over-loaded with features). But a lot are not happy with their current setup and know there is room for improvement.
So enter Lesson.ly, stage right :-)
