We've got 35 programmers/devops people at BlockTrades (well, technically they work at other associated companies I'm involved with, since BlockTrades doesn't directly employ anyone), and 14 are currently working on Hive (one or two of them, like me, also work some on other projects we have, but most are full time or more just on Hive).

We're continuing to staff up, and we have two more programmers joining our team early next year, but I'm not sure which project they'll join yet.

Oh, it's also worth mentioning that I plan to fold some of the technology experience we gain on those other projects into our work on Hive. In particular, I view one project as partially research for later Hive work.
