WATCH: A Goldman Sachs Marcus exec explains why Apple is the perfect partner for their new credit card

• Apple was the perfect partner for Goldman Sachs' new credit card because of its focus on simplicity and putting the customer first, according to Omer Ismail, head of consumer digital finance in the Americas for Goldman's Marcus division.
• The only way to build a good business is to do right by customers, Ismail said on Monday at Business Insider's IGNITION: Transforming Finance event.
• Goldman developed its Marcus business by focusing on building an all-star team, not on bringing in "star athletes," he said.

Goldman Sachs' Marcus consumer division is one of the most closely watched businesses on Wall Street. Launched by the bank less than three years ago, it represents Goldman's first foray into retail banking and providing products to the "mass affluent."

Omar Ismail, who leads Marcus in the US, spoke on Monday at Business Insider's IGNITION: Transforming Finance event at the New York Stock Exchange about the bank's new credit card with Apple (and why hes not sweating profitability concerns), how Marcus' startup culture has spread throughout Goldman, and why it's changing its marketing strategy.
