I think it's good to point this out and think a little about what "health" means here. Looking at their consolidated financial data on page 11, you can see they spend about $1 providing a service someone pays $2 for. Then all the rest of it gets eaten up by salary, r&d and marketing. It feels like a very different situation than, say, Uber - where there's a question about if Uber can balance driver payouts and customer fees in a way where they make money. DO, instead, is already turning $1 in goods into $2 in revenue and they're just looking to grow enough so that $1 in potential profit covers everything.
