They say real estate is a traditional industry, often a family affair, but many companies—and industry players—are getting bullish on real estate tech.

One member from Tishman in particular, Daniel Tishman, is leading the way for his family-run business, becoming chairman of Ecorithm, a software company that helps landlords improve building energy efficiency.

(Daniel's dad, John Tishman, studied electrical engineering and has been investing in tech for decades.)

Other real estate dynasties like the Kushners and Milsteins are also dipping their toes into the tech world, the Wall Street Journal reports. Thor Equities' Joe Sitt said he was "bullish" on the tech sector.

Of course, Airbnb and WeWork are two huge industry disruptors (with almost $40B in valuations between the two alone), while many others are making noise in the space as well. 

And while the potential payoff's huge—again, see WeWork and Airbnb—they're also quite the time commitment. And as more startups enter the lucrative space, the competition gets fiercer, leading to industry concern about a real estate tech "bloodbath" coming soon. [WSJ]
