MUMBRELLA - Apr 17 - Spark, launched by Chris Reed, helps professionals on LinkedIn match with other people on LinkedIn who are also looking for a relationship by combining Tinder with LinkedIn. The move comes following a number of reports involving women receiving unsolicited non-work related messages on LinkedIn. Reed said Spark would seek to avoid allegations of LinkedIn harassment and stalking by encouraging users to message potential dates on Tinder and use LinkedIn to determine whether the person 'fits the bill'.
