Great Technology, Great People, challenging "startup" mode opportunity
Pros
Red Balloon is well known and respected in the Security and Research world. The commercial products are good, and just need time and the right effort to gain more customers in Commercial. Great, smart group of people! If you're looking for a "startup" style opportunity, where you can make a big difference, but also with the financial security of a large list of government/research funding, this is the place. Red Balloon is demonstrably making the world of embedded devices safer for Customers and Consumers.
Cons
It can be a challenge to work in an environment with so many smart people (mostly PhDs in the field) and keep focus on what needs to be done to advance the business. Yet this can also be the fun part - if you enjoy the responsibility and opportunity to "show your stuff" and make a contribution in Research or R&D roles.
