Paubox, a secure email provider that specializes in the healthcare industry, today announced $4 million in Series A funding.

Launched in 2014, Paubox grew out of Pau Spam, an email filtering service founded in Hawaii more than a decade earlier. Today, the company has more than 3,000 paying customers, and is a a leader in the HIPAA compliant email space.

“The timing of our Series A funding is impeccable,” says Hoala Greevy, Founder and CEO of Paubox. “We will continue to provide market leadership in the HIPAA compliant email space, as more Americans than ever depend on their healthcare providers to provide secure and frictionless communication.”

The funding round was led by Minneapolis-based Arthur Ventures, which specializes in B2B software companies outside Silicon Valley. Arthur Ventures Partner Patrick Meenan will join the Paubox board of directors.

“We think Paubox is the best product on the market,” says Meenan. “High NPS (Net Promoter Score) and terrific customer retention is a fantastic combination and we’re excited to be partnering with them.”

Paubox helps healthcare organizations meet complex email security and compliance requirements in the U.S. Unlike incumbent solutions that force recipients to login to a portal to read a secure message, Paubox allows recipients to read a secure, compliant email in their inbox, just like a normal message.

With HITRUST CSF certification and a NPS of 80 for its core products, the company has uncovered strong product-market fit in the healthcare vertical. Paubox currently employs 34 people out of its headquarters in San Francisco.
