As most of you might know, we have recently located to a new place at Tempelhofer Ufer. We were literally outgrowing our small – but homely – old office at Kotti. Therefore we’ve now moved into a bigger and wow, also a protected as historic monument office building. That sounds pretty classy, doesn’t it? But it wouldn’t have felt right to keep it back from everyone we love, without hosting a proper office warming party. So on Oct 12th, friends, clients, family and the curious rang the doorbell to Guesstimate’s new home. To celebrate our completion of the new office, we served yummy cupcakes from Cupcake Berlin, loads of confetti (Alle Farben must’ve forgotten it here), a tiny golf course with high attendance, DJ sets by our talented friends Younotus, Perttu and many more, and not to forget a few drinks. Thanks to Absolut Vodka!

We are grateful for everyone’s support throughout the years and we’re delighted to have shared this event with so many of you. We had a blast! You can check out the photo gallery on our Facebook page.


Guesstimate enlarges its team with Andreas Weckenbrock as new head of label management.

We extend a warm welcome to Andreas Weckenbrock as our new head of label. Andreas has worked for Warner Music Group in Hamburg for several years.

“I am very much looking forward to taking on new responsibilities at Guesstimate. I am happy to be working with a young, motivated, competent and very likable team and also looking forward to teaming up with amazing artists, producers and partners. Guesstimate has developed in a remarkable way over the last years and is definitely well prepared for various requirements in this complex and dynamic market. I am pleased to bring in my experience and expertise and am quite confident that we will continue and extend the successful work with new ideas into the field of recorded music and content.” | Andreas Weckenbrock

Polytope Booking is very happy to officially seal the deal with Anne Karolczak aka Pretty Pink. The female DJ, risen from the deep & dark woods of the Harz in Germany, made a substantial way through the steaming and raging international club scene to manifest her belief in the very finest tunes of Nu Disco, Deep – and the most unique secret selection of House. Pretty Pink by now is a fairly well known artist within Europe. Her edit of Daft Punks Get Lucky truly turned into a underground hit and has been played by famous DJ’s around the world. 

Pretty Pink embodies a tasteful sound with a twist of madness that has lifted the crowds at gigs and festivals on a new level. Combined with years of professional jetset, she is a multitalented workaholic and it is with great pleasure, we work-a-holic as a team now.

“Bad Ideas make the best memories, even if you don’t remember them…” True to that motto, Alle Farben is putting out his second single from his latest Long Player “Music Is My Best Friend”. After the first hit single “Please Tell Rosie” (feat. YOUNOTUS), which has already achieved Gold status in Germany and Austria, this time the focus is shifted from Rosie onto the “bad ideas” people may have in life, which usually turn out to be the most memorable. Musically, the Kreuzberg resident adds more colorful elements to his wide palette of ideas this time out. This time beats are combined with chilled guitar fills and vocal hooks from Nashville resident Chris Gelbuda, who’s vocal crosses the track over into potential pop-hit territory.

The Berlin-based DJ also delivers a crazy video directly from Los Angeles, packed full of interest and including a wild chase. After “She Moves”, “Supergirl” & “Please Tell Rosie”, Alle Farben continues his story with “Bad Ideas” this late summer.

Berlin/Mumbai, June 24th 2016 Polytope Booking establishes a branch in India’s 12 million metropolis and is now represented internationally. Under the umbrella of Guesstimate GmbH, the Berlin booking agency starts a counterpart in Mumbai. Polytope is extending their international roster next to artists like Alle Farben, YOUNOTUS, Pretty Pink & Parra for Cuva. From the years of work by Polytope Booking, the Asian market was extrapolated to Berlin booking. Therefore, it was only logical for their internationally oriented network to not only have a local partner but also an overseas branch in Mumbai. From now on, Aneesha Kotwani takes over the booking in Mumbai.
