I'm about to launch a very, very limited selection of lifetime subscriptions for PageHum to 20 users of the Pro and the Ultra tiers. This is to promote the offering, and it will of course lock these 40 users into lifetime access for these tiers without continued monthly/annual charges.
While @acadictive and I have discussed how this isn't a great business plan, I think since it's locked to a limited quantity of early adopters, it works out just fine.
Early adopters will be likely to:
complain (great feedback for improving)
share with others (proud of their early support, and will promote)
heavy usage (sounds bad, except the above will surface)
most likely to expand (they spent quick, they'll likely buy more stuff you do)
Let's prove me right or wrong with this offering. I'll post an update after with the success or failure of this program so you can decide.
