E-learning company Skillsoft has announced a deal to buy SumTotal Systems from US based private equity firm Vista Equity Partners for an undisclosed sum.

SumTotal provides flexible, human resources solutions to 3,500 customers and 49 million users worldwide 

Skillsoft said the acquisition will expand its solution portfolio and global reach.

Skillsoft provides electronic learning solutions to over 6,000 customers globally, including companies and governments. It uses cloud computing, which allows clients to reduce costs by ditching bulky local servers for network-based software and storage in remote data centres.
