There are lots of opportunities for RE tech startups, you just have to find the right itch to scratch. We started working on our real estate venture about 18 months ago, with a public launch last summer. The real estate industry has been a key partner in our growth path.
As for capital, I have yet to encounter easy money, anywhere. However there is definitely willingness on the part of real estate professionals to try something new and pay for it, and there's investment capital out there if you're really onto something.
Despite what many say about the industry being a dinosaur, it's very much forward-looking, and willing to take risks.
