Company Overview

About Prosper

Prosper Marketplace is one of the original peer-to-peer lending platforms in the United States, founded in 2005 by Chris Larsen and John Witchel in San Francisco as the first U.S. marketplace lending company connecting individual borrowers with investor lenders. The company offers personal loans ($2,000-$50,000), home equity loans, and a proprietary credit card, serving borrowers with fixed-rate installment loans for debt consolidation, home improvement, major purchases, and other personal financing needs. Since its founding, Prosper has facilitated over $24 billion in loans, making it one of the most established names in the marketplace lending industry.

Business Model & Competitive Advantage

Prosper has raised $680M in total funding from investors including Sequoia Capital, QED Investors, and Meritech Capital Partners, with a current valuation of approximately $550M. In April 2025, Prosper entered a $500M forward flow agreement with Fortress Investment Group and Edge Focus, a capital commitment designed to expand loan origination capacity by providing dedicated institutional funding for new loans. The company employs approximately 492 people and continues to operate as a significant player in the consumer lending market despite facing a more difficult fintech funding environment than its peak 2015-2021 years. In September 2025, Prosper disclosed an unauthorized access incident affecting 17.6 million email addresses and associated customer data, which the company reported to regulators and impacted users.

Competitive Landscape 2025–2026

Prosper competes with LendingClub (which converted to a bank), SoFi (which went public via SPAC and also became a bank), Marcus by Goldman Sachs, and traditional personal loan lenders. The marketplace lending model has evolved significantly since Prosper's founding: institutional investors now provide most of the loan capital rather than individual retail investors, and the peer-to-peer framing has given way to a direct lender model. Prosper's brand recognition and two-decade track record differentiate it from newer entrants, while the company continues to invest in product expansion (home equity, credit cards) and digital underwriting capabilities.
