PayZen, based in San Francisco, announced a $20 million equity round led by 7wireVentures, bringing its total funding to $40 million, including $15 million from a Series A round last year. In addition, the company announced that it has received a $200 million warehouse credit facility from Viola Credit, the debt arm of Israeli investment firm Viola Group.

The firm provides health care providers with lower upfront payments for medical bills before attempting to collect the full amount from clients over a longer period of time. It keeps the difference instead of charging them interest or fees.

In a statement, PayZen said that the credit facility from Viola Credit “significantly” expands its existing line of credit, and that the new funding “will accelerate its mission to make personalized, affordable, no-cost payment options available to all Americans, building on its technology lead to become the embedded finance platform of the health care industry.”
