Shopify has emerged anew in the direct-to-consumer era. The 15-year-old e-commerce platform that powered the small business segment is worth $25 billion. Now, it's setting its sights on the larger brands.

Abaza discusses evolving as a platform to retain bigger brands as they grow, why the DTC companies are here to stay and more.
