An SEO company is making a lot of money.

After years of hard work, a team of Web developers at the University of Washington and their colleagues have been paid a whopping $1.5 million in an offer to build a social media application for the city of Seattle.

It’s the largest paid employee payout in the city’s history, according to the Seattle Times.

The tech team’s offer includes $600,000 in stock awards.

The company, called KEN, also announced plans to expand to the United States.
