Instacart and Klaviyo‘s public listings last week signaled the partial reopening of the IPO market for venture-backed tech companies.

Klaviyo’s stock popped to $36.75 in its NYSE debut, above its IPO price of $30. The developer of a marketing automation platform with large and fast-growing revenue, Klaviyo was a near-perfect IPO candidate from investors’ points of view. Which companies might be next in the pipeline isn’t so clear.

Here are 15 US venture-backed enterprise SaaS unicorns likely to follow in Klaviyo’s footsteps to an IPO. The list was created using PitchBook’s VC Exit Predictor, which calculates exit probability using a machine learning model that is fed historic and real-time data on private company exits. The predictor draws from 34 inputs related to company characteristics, financing and investors.
