Primer Co-Founder Gabriel La Roux stopped by the media room at the Money 20/20 event to chat with Mike Baer about end-to-end payment flow applications his company has developed. Streamlined integration of a multitude of payment and commerce services is what La Roux's company offers businesses across the spectrum. They have primarily a usage-based model, according to La Roux. He discusses Primer's unique approach to payments and the future of these kinds of applications.
