Fund That Flip

Fund That Flip is a Cleveland- and New York-based real estate fintech founded in 2014 that lends to residential redevelopers and offers passive income opportunities to accredited investors, having originated more than $2.6B in short-term hard money, fix-and-flip, new construction and DSCR loans. In 2022 it acquired FlipperForce, a web-based project management, deal analysis, rehab estimating and job-costing platform for house flippers and builders, and in September 2023 the combined lending and software business rebranded as Upright (upright.us). The company's developer surface is the FlipperForce Public API — an OpenAPI 3.1 documented REST API at tools.flipperforce.com/api/v1 covering projects, expenses, income, receipts, photo logs, project updates, companies, expense accounts and the workspace activity log.

Fund That Flip publishes 15 APIs on the APIs.io network, including Activity Log API, Attachment Upload API, Company API, and 12 more. Tagged areas include Company, Real-Estate, Lending, Construction, and Project Management.

Fund That Flip’s developer surface includes authentication, developer portal, documentation, API reference, getting-started guide, support, engineering blog, and 22 more developer resources.
