David Mandell, co-founder and chief executive of the Boulder startup, declined to comment Thursday because the funding round is still open. According to the Form D, PivotDesk can raise up to $4 million in the round.
Founded in 2012, PivotDesk helps match businesses or landlords who have extra office space with startups or small businesses that need new digs but also require more flexibility than a long-term lease would allow.
The company is headquartered at 1910 Pearl St. But its online marketplaces cover Boulder, Denver, Boston, New York, San Francisco and Portland, Oregon.
A graduate of the TechStars startup accelerator in 2012, the company raised a $3 million funding round in September of that year, with participation from Boulder-based Foundry Group and Techstars co-founder David Cohen, among others.
