  2. Gefen is an incredible product visionary. She’s led Celtra through crucial industry transitions, the race towards mobile and now the consumer direct revolution. While we work on separate teams, I’m continuously impacted by her fearless attitude and her passion to build a product that positively impacts the advertising industry. She’s a dreamer, so much that inspires anyone she comes in contact in.
