Engrain, a vendor of interactive mapping and data visualization, announced that it had closed a $12 million Series A round from RET Ventures. That makes a total of $16.7 million in funding to date with seed rounds in 2019 and 2020, according to startup data source Crunchbase.

The news comes on top of an additional announcement that Zillow had integrated the company's software to provide visual location information at its site on apartments and amenities on 3,600 multifamily properties.

"With this capital in hand, Engrain will invest in a wide range of platform improvements, including an innovative marketplace with automated processes around license management and sharing property maps with vendors," a press release stated. "Engrain will also add pathfinding capabilities for visitors to navigate the most efficient paths around the property and surrounding community — a valuable tool for prospective residents, delivery personnel, contractors and maintenance staff."
