Kinglet closed $500,000 in angel round funding, officials there announced Tuesday.

Kinglet is an online marketplace allowing entrepreneurs and small businesses to rent office space as small as a desk and chair.

Investors include Merkle CEO David Williams, Under Armour CFO Brad Dickerson and Millennial Media co-founder Chris Brandenburg.

Jeff Jacobson, Kinglet’s cofounder and CMO, said in a release that the funding will allow Kinglet to expand to Washington and Philadelphia, as well as boost hiring.

“Hiring talented developers will also be a priority as we continue to provide an innovative online marketplace for landlords, entrepreneurs and small businesses,” Jacobson said.

Brandenburg, who left Millennial in 2013, was also involved in the $7 million Series A round of investments into Canton-based OrderUp.

“Jeff and [cofounder and CEO Alex Kopicki’s] entrepreneurial pedigree, having previously launched a very successful commercial real estate startup, and their deep experience in the space give them a very unique perspective on the challenges faced by all entrepreneurs as they relate to office space,” Brandenburg said in the release. “Combining that with the simple fact that the market is clamoring for the changes Kinglet’s solution provides — variety, flexibility and simplicity in attaining office space — made this investment an easy choice for me.”

Kinglet, a Betamore graduate, has already inked partners in the form of Corporate Office Properties Trust and Maryland Nonprofits and manages leasing for 285 spaces in Baltimore and suburbs including Towson, Annapolis and Gaithersburg.
