The firm issued $3.7 billion of ABS during the second quarter, a 76.2% sequential jump. Pagaya aggregates auto loans, unsecured consumer loans and point-of-sale financing products.

Byzfunder issued its first ABS last week, a transaction that was three times oversubscribed by investors. Repeat issuers are also ramping up originations and issuance volume.

The new partnership adds a new funding channel for Upstart’s growing unsecured consumer loan originations.
