Gregory Cooke is CEO of Constant Close, a sales agency that removes the need for sales calls and therefore streamlines your sales process. His entrepreneurial journey began when he started selling memory cards from eBay while still at school. Much of Gregory's ambition, drive and resilience was born out of his struggles with dyslexia, PTSD and mental health issues. He also talks about his plans for Friday Founders Foundation—a network of mental health support for entrepreneurs.
