SoFi Technologies, Inc's (NASDAQ:SOFI) second-quarter earnings were packed with record numbers, from revenue and loan originations to member growth.

But the most important metric may have been one that received far less attention.

"For the first time, we added twice as many products as members, a major milestone that underscores the trust members place in SoFi and the power of our 'everything app'," CEO Anthony Noto said in the earnings press release.

SoFi brought in a record 2.2 million new products versus 1.1 million new members during the quarter.

The company also said 51% of those new products were opened by existing members, a sign that customers are increasingly using SoFi for more than just a single financial service.
