It is really a mystery when you have someone who has an interest in an internet company that has not gone public. I know some people who were on the ground floor of internet companies and they made chicken change until the company was sold. I also know people who used internet start ups to write themselves huge checks before the company was economically viable and drove the company into the ground.
I would suspect that Lukezic makes mid six figures and lives in a 1500 sq ft condo in San Fran that costs as much as a 4,800 sq ft house on 2 acres in Dallas, TX.
Frankly, I did not think that AirBnB would go as far as it did. Actually should be a lesson to US runners. Run as hard as you can when you race. If you get injured and never get to run again, you will just end up making tons of money in another field.
