Clearwater Analytics Holdings Inc. (CWAN) said Monday an affiliate of SIVB Financial Group’s (SIVB) Silicon Valley Bank (SVB) is a client, but represented less than 1.5% of recurring revenue a year as of Dec. 31. Clearwater moved to reassure investors after its stock dove 15.2% the past two days to close Friday at a 7-month low after SVB’s troubles became public, and as SVB was placed in receivership by regulators on Friday.
