I'm ambivalent about this. Having been through a few different startups with various degrees of marketing, it seems like the issue is really sensitive to your product and your schedule.<p>Mog.com started out with minimal hype despite a lot of effort by its CEO, and had an very (almost disastrously) slow startup phase. When we ran into implementation difficulties we compounded this slow-start problem even more. Mog managed to pull through this because of prudent financials and perseverance, but it was a near thing.<p>Powerset had the opposite problem, we had so much hype we didn't know what to do with it. What Powerset delivered was pretty impressive, but much less than what people expected. Cries of "Deeply Disappointed!" rained down on us like drops of acid, and we were powerless to do anything but deliver on what we could and say the rest was either too expensive or too difficult for the moment. But we <i>did</i> have a lot of users and interest, so we had a huge launch.<p>Now I'm at BankSimple, which is somewhere in between these other plans. BankSimple is aggressively talking to people and getting their message out, so there is some pent-up demand. We're also very diligent about responding to people as people, we do a bit of research before replying to (almost every) email. This means that we get some impatient tweets and messages (“Who cares what you look like? Where is your service?!”) asking for unreasonably fast development time, but it also means we get a lot of insightful feedback and commentary.<p>Our biggest obstacle seems to be controlling the hype. It's very easy for people to build up what we promised into veiled hints some kind of complete reform of the US financial system, which is probably an unreasonable launch goal. ;)
