Plaid Technologies Inc., whose software allows a variety of financial-technology startups to access their customers’ bank account information, has raised $44 million in a new round led by a fund at Goldman Sachs Group Inc.

The new funding is a boost for apps and websites that use Plaid, which has now raised about $60 million total, as they work to ensure access to customer data held by banks.

In recent months, banks and fintech firms have clashed about some of the ways that the firms access bank-customer account data, including concerns about security of passwords and surges of data traffic to banks’ websites.

Many upstart financial-services providers such as online financial adviser Betterment Inc. use Plaid’s software to access or check customers’ account data when providing mobile and web services like budgeting, investing or lending.

Zach Perret, co-founder of Plaid, said that the past six months have seen “increasing cooperation” between banks and fintech firms, though so far that hasn’t led to a resolution. “There’s an active discussion in the industry, and we think consumers should have access to their data, and should be able to utilize it when and where they need it,” he said.
