Wealthfront, the startup that helped popularize the robo-advisor style of automated investing, filed for a U.S. initial public offering Monday, making it the latest in a wave of fintech firms going public this year after the likes of Chime and Klarna.

The company in June filed confidentially for an IPO, but waited until now to make that filing public. That signals that Wealthfront is planning on kicking off its roadshow to pitch shares to investors; an IPO listing typically follows weeks after the S-1 filing is made public.

Wealthfront, led by CEO David Fortunato, had $88 billion in assets on its platform and served 1.3 million customers as of July 31, according to the filing.

“Digital natives typically have large liquid savings with long time horizons ahead, and they are undeterred by corrections and bear markets,” the company said.
