Note that there is not any rough revenue multiple that would apply in a broadly formulaic way for early-stage companies. They are all unique to some extent along axes that matter to investors (addressable market, growth rate, competition, etc.).
However, a couple of numbers from TFA might support the notion that DSC did ~$175m last year:
"“We have 2 million members that get a shipment every month or every other month"
...
"On average, the company’s customers pay a subscription fee of about $7 per month"
If those are both accurate, that's a $168mm run rate. (Right, that's not TTM, but if the company is growing rapidly, investors will want to have more of a forward bias and so TTM becomes less relevant.)
