Identified matches at FTDNA, Family Finder, and at 23andme, Relative Finder

I have 330 matches in Family Finder at FTDNA and have identified 13 relationships.

I have 1440 matches at 23andMe and am Sharing Genomes with 402. I have identified 15 relationships with those 402.

The success ratio at both services is comparable at about 4%.

I also have matches at GEDMATCH, but I have not been successful in identifying the relationship with any one there who is not already identified in Family Finder or Relative Finder.

If you are in the 23andMe database, a new feature of Ancestry Finder allows you to compare all of your matches and their matches to see if there are clusters at common locations. See this post for details on a method to download all your AF matches and their matches and use a spreadsheet for triangulation of the results:
