4490 Ventures has reinvested in Trainual, participating in a $27m series B round a year and a half after having co-led the series A.

Trainual, a US-based business knowledge transfer platform, picked up $27m in a series B round backed by 4490 Ventures, the venture capital firm co-founded by Wisconsin Alumni Research Foundation, yesterday.

Altos Ventures led the round, which also included Math Venture Partners, PHX Ventures and assorted private investors.

Trainual operates a platform that helps small businesses onboard, train and scale their teams. The company has attracted more than 5,500 clients across 177 countries to date, having experienced rapid growth due to pandemic-induced moves to working from home.

The series B capital will allow Trainual to further develop its offering and to hire more than 50 staff over the coming year.

Trainual previously raised $6.8m in series A funding co-led by 4490 Ventures and Math Venture Partner in 2019. It also identified PHX Ventures as a series A investor as part of its latest announcement.
