LendingClub loans under $100,000 are unsecured and do not require any kind of collateral. Loans of $100,000 or more require a blanket lien on your business assets as collateral. All LendingClub loans do require a personal guarantee—basically, if you end up defaulting on the loan, your personal assets are on the line. That might sound scary, but personal guarantees are pretty standard. As long as you don’t default, you don’t need to worry about it.
