Other investors did include Insight Partners and Rebate Networks.
Like its rival, DealGuru is also owned by a German incubator, Rebate Networks.
Ensogo is backed by Rebate Networks, a leading international VC specializing in the social commerce space.
But Berlin-based Rebate Networks is taking the idea of copying Groupon to the extreme.
And it looks as if Rebate Networks are very successful with their copy-and-deploy-fast-worldwide approach.
Groupon proper is leading in Japan and Germany (where Rebate Networks' clones Piku and Daily Deal are said to be the No. 2 players).
Groupon entered those markets by buying local clones, and it's obvious buy-outs are what Rebate Networks ultimately aims for with its portfolio companies, too.
Very quietly, Rebate Networks either helped to set up or invested in existing Groupon-like sites in South America (four different countries), Europe (17 countries) and East Asia (eight countries).
Update 2: Ok so we understand Mangrove Capital Partners, Brehm and Maaß were no longer investors, but Insight Ventures Partners, Rebate Networks and AdInvest were.
Melanie Roth, product manager for German daily deal company Rebate Networks, was sitting at her desk in her office in Berlin, when her colleague sent her a link she thought she might be interested in.
