Prosper Marketplace Center Data Breach Lawsuit

Prosper Marketplace, Inc. and Prosper Funding LLC, a prominent San Francisco-based fintech company, recently reported a data breach that potentially exposed sensitive personal information, including Social Security numbers. If you were impacted by this breach, you may have legal options to seek compensation for the incident.

Prosper Marketplace’s Data Breach Investigation

On September 1, 2025, Prosper Marketplace discovered unauthorized activity on its systems. Upon detecting the breach, the company immediately took steps to stop the activity, enhance security measures, and begin an investigation with a leading cybersecurity firm. Prosper also reported the incident to law enforcement and is fully cooperating with authorities.

Although the company found no evidence that customer accounts or funds were compromised, the breach involved unauthorized access to confidential, proprietary, and personal information. This included Social Security numbers and potentially other sensitive data obtained through unauthorized queries on company databases storing customer and applicant information.

As the investigation progresses, Prosper Marketplace is assessing the full extent of the compromised data. The company has pledged to notify affected individuals and offer free credit monitoring services to help protect their personal information. Prosper Marketplace continues to monitor accounts and implement safeguards to prevent further incidents.

When Did This Breach Occur?

The breach was detected on September 1, 2025, but the unauthorized access to Prosper Marketplace’s systems occurred prior to this date. The company has stated that it acted quickly to stop the unauthorized activity and strengthen security, and it is still working to determine the full scope of the incident.

What Information Was Breached?

The Prosper data breach involved the exposure of the following sensitive personal information:

• Social Security numbers
• Confidential and proprietary data (specific details not yet disclosed)
• Personal information from customers and applicants

While the investigation is ongoing, Prosper has confirmed that no customer accounts or funds were compromised. However, the breach still poses significant risks related to identity theft, fraud, and the misuse of personal information.
