Built on lines of dense computer code, tech startups can seem ethereal and inscrutable. Real estate, on the other hand, is a more concrete business.

Joining these two seemingly disparate fields was the focus of a demo session this week at the Williamsburg Hotel, where five financial-tech startups pitched potential customers and investors on how their platforms streamline, open up, or otherwise improve the process of building, buying, and selling commercial and residential real estate.

For investors, the service would reduce transactions costs and make a real-estate portfolio more liquid. For owners, it would unlock more capital and streamline transactions. While Meridio won’t provide market intelligence about properties to invest in, prospective investors can call on their own experience, says Conroy, who previously worked for the National Association of Realtors.
