A startup out of Boston, Knox Financial, is aiming to help people identify and manage residential rentals with its algorithm-based platform, and it’s raised a $10 million Series A to help it further that goal. Boston-based G20 Ventures led the round, which included participation from Greycroft, Pillar VC, 2LVC, and Gaingels. The investment brings Knox’s total raised since its inception in 2018 to $14.7 million. The company closed on a $3 million seed round in January 2020, led by Greycroft. Knox co-founder and CEO David Friedman is no stranger to startups. He founded Boston Logic — an integrated marketing platform and online marketing services for real estate offices and agents — in 2004. He sold that company (now under the name Propertybase) to Providence Equity for an undisclosed amount in 2016.
