@iseoghan, LearnUpon looks good. Few thoughts if you do outbound sales :
a) Reach out to companies who have raised Series A and above and have minimum 100 employees.These are the companies who are expanding and will need product like yours.
b) Target companies who are rapidly growing and hiring lot of people. Your product will be most suitable to them.
Have few more thoughts in mind. Let me know if it makes sense.
