Background
Berlin-based Greentech Show GmbH runs the GREENTECH FESTIVAL, an international platform for green technologies and sustainable business models: a three-day conference with keynotes, panels and workshops, an accompanying trade exhibition, the Green Awards Gala, the GTF Career Day and a matchmaking app for live networking. The event connects startups, investors, policymakers and researchers to drive decarbonization.
The Challenge
Despite active email and LinkedIn campaigns, Greentech was losing a lot of time to laborious manual data maintenance and research. On top of that, unnecessarily individual outreach led to weaker conversions: many leads received a reply too late. Better processes were needed to increase registrations and reduce manual effort.
