Design Scope
End-to-end design · Full production · Main event & official side events · On-site supervision
Design Objectives
Slush motto is “never settle”. Every edition aims to reinvent the event’s look and feel without compromising its distinctive identity. We work to protect the feeling that Slush is not like any other tech event.
Sun Effects design concept
A startup conference that feels closer to a rave than a traditional tech event.
Sun Effects has designed and produced Slush since its beginning in 2009. Over the years, we have created stages featuring lasers and projection mapping, as well as spaces built from wood and sauna stones. We have designed decorative installations ranging from building-sized waterfalls to environments made with several tonnes of sand, and developed systems supporting more than 25,000 individual meetings every year.
Most importantly, we have helped Slush grow to its current scale without compromising its distinctive visual identity.
The main event and official side events are built around an annual theme set by Slush, which Sun Effects transforms into a comprehensive design concept. The process begins in January and continues until the doors open in November.
