A lot has been written about lean startups and how to continually test and validate assumptions along the way. Below is Engage-a-Pro's timeline from conception to launch:
Idea: November 22, 2011
First market survey with C-suite executives: Nov 30 - Dec 2, 2011
Business incorporated: Dec 5, 2011
First landing page: January 1, 2012
Adwords campaign data gathered: Jan - Mar, 2012
Alpha launch: March 31, 2012
We plan on using the data gathered over the next several weeks to guide the next iteration of the application. We already see lots of improvements coming.
