Hundreds of millions of dollars in sales doesn't count as success? Which non-yc hardware companies started in the last several years would you count as successful?
Thalmic has hundred of millions in sales!? or were you referring to another one from the list?
It might. But profitability is important as well. Not a comment on any particular company but the idea that a company that has millions in revenue but no profits (and is floated by investors) is successful is not absolute.
