What do you do?
I’m the founder of Signature Socials, a New York-based social media and creative agency. We do three things: 1. We build distinctive, high-end websites; 2. we manage the social media accounts of companies, organisations and entrepreneurs. 3. and we build the digital strategy that connects it all. That strategy is different for every client. Sometimes the goal is revenue. Sometimes it is audience growth, traffic, authority, visibility or positioning. But the principle is always the same: if you have spent years building something great, the way you show up online should communicate its value immediately. You digital presence should work as an asset for the business, the brand and the person behind it.
