Rand dropped out of the University of Washington in 2000 to work full-time at his mother’s small business marketing firm as a web designer.

In 2007, Rand became CEO of SEOmoz, Inc (now called Moz), the software company he co-founded with his mom based on the blog’s success. That same year, he proposed to his longtime girlfriend, Geraldine DeRuiter, with a TV commercial that received widespread publicity (and, later, an awkward appearance on the Oprah Winfrey show). The two married in 2008 in a move Rand consistently refers to as the best, luckiest one of his life.
Over 7 years as CEO, Rand grew Moz from 7 employees to 134, revenues from $800K to $29.3mm, and traffic from 1 to 30mm annual visitors. He raised two rounds of funding ($1.1mm in 2007 and $18.1mm in 2012), led three acquisitions, and, in 2013, re-branded the company from SEOmoz to Moz, shifting focus from exclusively SEO tools to broader web marketing software. Rand stepped down as CEO in February of 2014 during a rough bout with depression and left the company 4 years later. He remains chairman of Moz’s board.
Rand is also the co-founder of Inbound.org, a site to dedicated to sharing articles about marketing from across the web, alongside Dharmesh Shah. The site was sold (for no profit) to Hubspot in 2014.
