Allbirds, the San Francisco-based casual footwear and sneaker maker, is in the process of interviewing banks in preparation for an initial public offering (IPO) according to a report in The New York Times DealBook.

The direct-to-consumer brand, a certified B Corp, was last valued at roughly $1.7 billion in a $100 million funding round last September.

Allbirds has 23 stores, including locations in London, Berlin, Shanghai, and Tokyo.
