Redfin and Zillow might have beat you to it but real estate has a lot of old-fashion practices. I think there is a lot of space in that industry to improve. One anecdote I have a friend (~30) who works in real estate appraisal. He says the industry is run on excel. While it might not make you a unicorn, you could definitely make money having a better solution.
