Goldman Sachs and JPMorgan Chase are among a group of institutions reportedly backing Axoni, a capital markets technology firm that specializes in distributed ledger infrastructure.

The New York-based Axoni is expected to announce a fund-raise this week of between $15 million and $20 million, Reuters reported late Monday. Goldman Sachs and JPMorgan declined to comment. Axoni did not respond to a request for comment by deadline.

Axoni and JPMorgan have collaborated at least twice this year to test the startup's technology, including once in October when it ran a proof of concept for post-trade processing of over-the-counter swaps along with Barclays and Credit Suisse. In April, it did the same for post-trade life-cycle events management for credit default swaps with Bank of America Merrill Lynch, Citi and Credit Suisse.

In September Axoni collaborated with the bank consortium R3 CEV – which Goldman Sachs exited last month – on a reference data management proof of concept with seven member banks including Citi, Credit Suisse and HSBC.
