Gustav is a vendor management platform (VMS) and sub-vendor marketplace for the staffing industry, enabling staffing firms to source talent from their trusted vendor network, share open jobs, collect and screen candidate submissions, run standardized hiring pipelines, schedule interviews, message vendors, and track performance in one place. Vendors organize into "Gustav Circles" with tiered job-release controls, and candidate submissions sync to applicant tracking systems including Bullhorn and JobDiva. Originally a Speedinvest-backed startup, Gustav is now operated by the member-owned Fuse Cooperative (a Colorado Limited Cooperative Association) and bills itself as the staffing industry's largest sub-vendor marketplace. Gustav is a SaaS web application; it does not currently publish a public developer API, OpenAPI specification, or SDKs — integrations are delivered through the Bullhorn and JobDiva marketplaces.
