Founders Fund is a venture capital firm, not a federal contractor. As a VC firm, it does not directly receive federal contracts. However, its portfolio companies may hold federal contracts. USAspending.gov tracks federal spending to contractors and grant recipients, but venture capital firms like Founders Fund would not typically appear as direct contract recipients. The relevant public records would be for Founders Fund's portfolio companies that do business with the federal government, most notably Palantir Technologies and SpaceX, both of which have substantial federal contract histories.
