I am creating a new website and it's a very common one, about upcoming events. The difference of me and the competition is how I deliver the events to the people that is kind of strange and clever also.
Can this be my unique selling point? Or in the battle of the startups I need more than this?
USP is overused in many circles - and with different definitions.
Wikipedia uses the definition penned by Reeves in "Reality in Advertising" as:
The battle is not between startups but between your defined target market, their price anchors, and the alternatives they use to address the problem / condition you assume that they have. How many members in the target market have you interviewed? Discussed / validated the problem and their desire to address it? Their willingness to pay for the "solution" you offer?
The natural outcome of this effort is your USP (or a pivot towards finding a lucrative USP).
While its not easy to do, the nice thing is - all this can be done before ever writing a single line of code: which would likely be easier (and cheaper) than trying to convince someone to use a service that doesn't meet their needs.
