assuming the following hold true
1) company is bootstrapped
2) company has built a strong tech platform in its industry and is looking to have the first set of users.
3) the company's target segment is buyers of software
4) there are invites from Launch events like Demo/TC Disrupt
3) the company's target segment is buyers of software
Huh? Who is that? Isn't it like a food company saying their target market is food buyers? ;-)
I mean that could be anyone that has ever bought a piece of software.<p>As for return on investment - did you do your math?
You know depending on your potential revenue/user it could be anywhere from being a terrible idea to being a phenomenal one.<p>Of course not that revenue/user is the only metric. But if you really need a big volume of customers to make a penny or two then obviously that kind of marketing is dubious and screams web 1.0.
Do NOT hope that because of having an event it goes viral and out of nowhere you'll get tons of customers.
