3. LendingClub

LendingClub is among the most well-known peer lending platforms, having facilitated over $80 billion in loans since launching in 2007.

  • Minimum credit score: 600
  • Origination fees: 3%–8% of loan amount

4. Yieldstreet

Yieldstreet expands the peer-to-peer lending model beyond personal loans by connecting investors with alternative asset classes including real estate, legal finance, and private credit. Unlike traditional P2P platforms focused solely on consumer loans, Yieldstreet targets accredited investors seeking portfolio diversification with higher yield potential. Minimum investments typically start at $10,000, and annual returns have historically ranged from 8–15% depending on the asset class.

  • Multiple asset classes beyond standard personal loans
  • Management fees typically 1–2.5% annually

5. Funding Circle

Funding Circle is a small business-focused P2P lending platform that connects investors directly with established small businesses seeking growth capital. Rather than funding individual borrowers, investors on this platform earn returns by lending to vetted SMEs across the U.S. and UK.

8. Bosonic

Notable features:

  • Real-time settlement reduces counterparty and credit risk
  • Built for institutional lenders and P2P platform operators
  • Supports multi-asset collateral and netting agreements

9. Porter Finance

Porter Finance is a decentralized borrowing protocol that allows DAOs and crypto-native organizations to issue fixed-rate bonds, functioning similarly to how business-focused P2P lending sites connect institutional borrowers with yield-seeking lenders. It gives lenders predictable returns through convertible bonds rather than traditional loan structures, with repayment backed by on-chain collateral.

What you get:

  • Fixed-rate bond yields with defined maturity dates
  • On-chain collateral backing reduces lender default risk

13. SoFi

SoFi began as a peer-to-peer lending platform connecting borrowers with investors but has since evolved into a full-service online lender. It remains relevant to P2P lending comparisons because it offers personal loans with competitive rates, fast funding, and no origination fees — features rooted in its marketplace lending origins.
