Amber Venz Box always knew she wanted to run her own company. But when her marketing business got intensely popular, she was still in her early 20s — and she didn't exactly know what to do. When Box co-founded Dallas-based LTK in 2011, her goal was simple: Develop affiliate marketing tech to monetize her fashion blog. Today, LTK is a $2 billion company that connects influencers and bloggers with retail brands and their advertising dollars, but it didn't exactly go smoothly at first. "Being a young woman with little experience was like trying to run with boulders on my back, honestly," Box, 36, tells CNBC Make It.
