A new entrant to the “people search engine” space 123People.com. According to TechCrunch (waiting for private invite to further test) the company is in private beta only. Where 123People differs a bit from competitors is by aggregating more tangible personal information like phone numbers, email addresses etc. This could be one area that places that company in trouble based on where the exact sources the data is aggregated from. Currently it’s taken from publicly available information and social networks. “People search” startups are crucial this year as the social graph API matures and data is continually swapped and aggregated between disparate sources. This will only further beg the question who owns the data…the controllers or the controllees.
