Ms. Janet Tavakoli had published the article "How to Land an Angel Investor"
Although angel investors mainly do not invest in dating sites, I agree with her in "Pitch a dating site that sounds like 20 other dating site pitches in the last month. I'd be delighted to introduce you to each other." because persons/daters do not pay for social discovering, for finding new friends, they will pay only for high effective compatibility matching.
See failed proposals like TheCompleteMe, SmartDate, HowAboutWe, Zingl, Engage (rebranded to Ignighter group dating, then rebranded again to StepOut), Thread, Triangulate, Gelato (then rebranded to Twnty), WooMe, 12Like, LittleHint.
WorldWide, there are over 5,000 -five thousand- online dating sites
but no one is using the 16PF5 (or similar) to assess personality of its members!
but no one calculates similarity with a quantized pattern comparison method!
but no one can show Compatibility Distribution Curves to each and every of its members!
but no one is scientifically proven!
Online Dating for serious daters does not need to be more social, it needs to be more effective/efficient. It needs to reduce the false positives problem.
The Online Dating Industry needs innovations but they will come from only one source: the latest discoveries in theories of romantic relationships development with commitment.
Compatibility is all about a high level on personality* similarity* between prospective mates for long term mating with commitment.
*personality measured with a normative test.
*similarity: there are different ways to calculate similarity, it depends on how mathematically is defined.
STRICT PERSONALITY SIMILARITY and not "meet other people with similar interests"
What comes after Social Networking?
My bet: The Next Big Investment Opportunity on the Internet will be .... Personalization!
Personality Based Recommender Systems and Strict Personality Based Compatibility Matching Engines for serious Online Dating with the normative 16PF5 personality test. The market remain enormous!!
