Acorns, an app that aims to simplify personal investing, announced today that it has raised $30 million. PayPal, Rakuten, and Greycroft participated in the round.

Acorns CEO Noah Kerner*, new to the company as of this year, called the PayPal investment “strategic” and said the partnership “will make it possible to bring the benefits of micro-investing to more and more people around the world.”

The company declined to share what, exactly, it plans to do with the $30 million, aside from saying that the cash will enable it to expand. However, some sort of product tie-up involving PayPal and Acorns seems likely, given the “strategic” language.

To date, 850,000 people have opened accounts on Acorns, the company tells us — up by 200,000 this year. Acorns declined to share how many of these people regularly use the service.

Acorns has publicly raised more than $60 million since 2012, including a $23 million raise in April 2015.
