Some eight months after it was reported that Ping Identity’s owners Vista Equity had hired bankers to explore a public listing, today Ping Identity took the plunge: the Colorado-based online ID management company Ping Identity has filed an S-1 form indicating that it plans to raise up to $100 million in an IPO.

The company was acquired by Vista in 2016 for about $600 million — at a time when a clutch of enterprise companies that looked like strong IPO candidates were going the private equity route and staying private instead. While the initial S-1 filing doesn’t have an indication of price range, Ping is said to be looking at a valuation of between $2 billion and $3 billion in this listing.
