Square flew under the radar compared to Twitter coverage but it too is on the same policy as Twitter given Jack is CEO of both. Noteworthy because it has a similar number of employees, an even larger market cap, and HQ'ed in the same location.
As Shopify? 35b (SQ) market cap vs 86b market cap (SHOP), SF vs Ottawa HQ, guess 4000 vs 6500 employees (based on linkedin numbers) is fairly close, but Square and Shopify are quite different.
