A statement from the company, which started life as a Web development firm in Brisbane, said the funding was led by SEEK and the Madrona Venture Group. New investor Salesforce Ventures and existing investors M12 (Microsoft's venture fund) and Our Innovation Fund also participated.
GO1 chief executive Andrew Barnes described growth over the last three months as "unprecedented".
"The use of online tools for training is now undergoing a structural shift,” he said. “It is gratifying to fill an important void right now as workers embrace online solutions.
The company said the number of organisations in Australia using its platform over the last year had doubled.
The funding, which will be used to expand in North America, comes soon after GO1 developed an integration with Microsoft Teams that lets organisations that use Teams learn directly within their workplace ecosystem.
“GO1 has been critical for business continuity as organisations navigate the remote realities of COVID-19,” said Nagraj Kashyap, Microsoft corporate vice-president and Global Head of M12.
“The GO1 integration with Microsoft Teams offers a seamless learning experience at a time when 75 million people are using the application daily. We’re proud to invest in a solution helping keep employees learning and businesses growing through this time.”
Apart from Australia, GO1 has offices in the US, the UK, South Africa, Vietnam and Malaysia.
