• Personal Authority would be a viable
channel to early adopters
• Customers would vote the problem as
“must-have”
• Customers would pay $49/mo
• Most early adopters did come through
blog and twitter
• Customers voted #3 problem as “must-
have”. Others as nice-to-have
• $49/mo works for customers with early
traction
•Test MVP based on “must-have” problem
•Test a “Free” model
