I think "Stealth Mode" covers a pretty large range of behaviors. We're far from stealth mode; we tell pretty much everyone everything that we're up to. We have no secrets and we handle all chats/negotiations/everything with all of our cards face up.

However, we only reveal all in face to face conversations, never in a broadcast. This gives us more opportunities to refine our message, collect feedback, forge real connections, and affords us the ability to do those things without burning opportunities for first impressions and without risking one skeptic from taring the collective perception by a group.

Using this strategy, we've been called "Stealthy" by people on the fringe of our current network. For some, that adds a little bit to the mystique and excitement, so they become willing to take a meeting with us. This strategy has been pretty successful so far.

EDIT: And if you're a super smart developer in the Seattle area looking to join a funded, early stage startup, we'll buy you a coffee/beer and reveal all! Email me: brandon@thinkfuse.com
