DocuSign, the 15-year-old private company that lets you affix your signature to a document electronically, has filed to go public.
The company has confidentially sent word that it will list its shares, a source with knowledge tells Recode, in what is shaping up to be a bumper year for tech IPOs. DocuSign was last valued on private markets at about $3 billion.
The IPO is expected to occur in the second or third quarter of this year.
The company has raised about $550 million, according to PitchBook, during its decade and a half as a private company.
DocuSign has said consistently that it planned to file for its IPO early in 2018. CEO Dan Springer only took over the job in January 2017, but has circled the early 2018 date repeatedly in interviews.
The confidential filing was first reported by TechCrunch. The company declined to comment to Recode on Tuesday.
DocuSign has reduced the hassle of requiring ink-on-paper signatures to be mailed around the country. The cloud company, which last raised money in 2015, has reportedly been the target of numerous acquisition offers from giants like Microsoft and Oracle.
