Locarta does location analytics: we analyse where groups of people go in the real world and look for patterns and insights. We’ve developed several products around this, such as measuring advertising effectiveness, or: „Does Lidl advertising really send people to Lidl?“. To do so we have a market research panel of people who’ve agreed to share their location with us (all in accordance with data privacy law, of course). We’re at over 2m users now, the data is flowing and is being used by 70% of the top retail brands in Germany. The current challenge is to smoothly scale the company as our customer base grows Currently we are 10 people, based in Berlin.
