The online education marketplace has now raised $113m in total, after securing $65m in a Norwest Venture Partners-backed series D round.

US-based online education marketplace Udemy secured $65m in series D funding today from investors including Norwest Venture Partners (NVP), the venture capital firm funded by financial services firm Wells Fargo.

Growth equity firm Stripes Group led the round, which also featured VC firm Insight Venture Partners (IVP).

Udemy runs an online education marketplace comprising more than 30,000 online courses put together by instructors covering a wide range of academic and skills-based subjects, and which can be bought on demand.

Part of the funding will be used to expand Udemy’s corporate offering, Udemy for Business, by equipping it with enhanced features and analytics, but it plans to focus its efforts on growing its market outside the US.

Around half of Udemy’s revenue comes from overseas, and the company plans to expand in East and South Asia, Latin America and Western Europe.

The round increased Udemy’s overall funding to $113m since it was founded in 2010. Its previous funding came from backers including NVP, which first invested in the company’s $32m series C round in May 2014, IVP, Lightbank, MHS Capital, Learn Capital, 500 Startups and Signia Venture Partners.
