A sorry for the miscalculation, did that on the way out the door.
Just thinking how big the market is. According to https://www.quantcast.com/top-sites/US?jump-to=110000 there are 110,000 sites with >10k monthly visitors, so I think that's the market of which they probably can get 30k users max for which they can charge $100/month on average: 30,000 $10012 = $36M/year revenue.
So for web, that's the cap it seems. According to http://www.appbrain.com/stats/android-app-downloads, there are 200,000 Android apps that have >100,000 downloads, which probably equates to 10k monthly active users, with iOS apps that's 400,000. So this will probably bring another $72M/year making it $108M revenue cap for Optimizely. So looks like the money for Optimizely is in the app market.
With 300 employees at max that's a burn rate of $15M + $25M marketing + $10M other costs, we got a profit of $58M = maybe $700M company, not bad.
Back of the envelope calculation, probably totally wrong, ok now back to work :)
I am involved in two websites that get a lot more than 10k visitors / month. Neither are listed in Quantcast. Using (crummy) traffic estimates based on Alexa ranks, I'd wager that there are at least 600,000 websites that would qualify for your >10k monthly visitors mark.
But I suppose it's all a moot point: They convinced at least one VC to invest, and that's all that matters. (Having used their product in the past, I probably would've invested too given the opportunity. Their product is pretty slick and saves a lot of time compared building your own A/B testing framework.)
