Lessen, a Scottsdale, Ariz.-based company that runs a marketplace platform for property services, is growing in Seattle as it gets set to open a new downtown office. The company already employs about 30 people in Seattle and is looking to at least double that number in 2022. A lease is being finalized for a space at 2nd Avenue and Columbia Street near Pioneer Square. Valued at over $1 billion, Lessen announced Tuesday that it raised $170 million in a Series B funding round. The company has raised $214 million to date.
