Australia’s Canva Inc. said its valuation hit US$15 billion ($20.1 billion) following a US$71 million investment, making the provider of design-collaboration tools one of the fastest-growing software startups in the world.

New investors Dragoneer Investment Group LLC and T. Rowe Price Global Technology Fund took part in the round with existing backers including Blackbird Ventures and Skip Capital, Canva said Wednesday. The Sydney-based company was previously valued at US$6 billion in June and US$3.2 billion in late 2019.

The online-design platform said it surpassed US$500 million in annualised revenue this year, a 130% year-on-year increase, while remaining profitable. It now has more than 55 million monthly active users, up from about 30 million in June.

“The company’s strong customer loyalty and consistent innovation has led to healthy growth,” Alan Tu, portfolio manager of T. Rowe Price Global Technology Fund, said in the statement. “We believe that they have the leadership team in place to continue on their path to becoming a much larger company.”

Canva was co-founded by Melanie Perkins, Cliff Obrecht and Cameron Adams. Launched in 2013, the product is used in 190 countries.
