GESIS Leibniz-Institut für Sozialwissenschaften rarely draws many bidders. Across 13 known contracts, they average only 2.1 bids per tender, well below the national average of 4.6 for this trade, so a well-prepared bid stands a real chance. Their latest award was a €525,700 contract (“Durchführung des GLES Querschnitts 2025”), which went to Verian, Mantle Germany GmbH, chosen from 2 bids.
We base these figures on the award notices we collect: every one we hold for this buyer, plus the last twelve months of awards in this trade across the country.
