Jeff founded and led Kolektiva, the first and largest daily deal site in Central Eastern Europe (CEE).

Initially launching in Zagreb, Croatia with self-funding, he set the vision and led the execution thereof to expand Kolektiva to eight countries, raise $10+ million in VC (a first in the region), employ 150 FTEs and build a $35 million business.

Kolektiva was acquired and merged with CEE internet powerhouse Neogen in 2014.
