Notarize, a Boston-based startup that connects customers with licensed remote notaries online, just disclosed it has raised $18.94 million in an equity round, according to a regulatory filing dated April 12.

It’s not the first time that the remote notary service led by Pat Kinsel disclosed a significant round of financing in a Form D filed with the Securities and Exchange Commission. In June 2016, the company disclosed that it had raised an $8 million round in just the same way. Later, it turned out that Polaris Partners led the round, with participation from Ludlow Ventures and Founder’s Fund.

As noted in the April 12 document, around $10.86 million of the total amount sold was from conversion of promissory notes.

In October 2017, Notarize landed a strategic investment from Second Century Ventures, the strategic investment arm of the National Association of Realtors. At that time, the amount of the investment was not disclosed.

Kinsel and Notarize did not respond immediately to a request of comment.
