What Equinox Software, Inc. / The Evergreen Experts does
Equinox Open Library Initiative Inc. is a 501(c)(3) nonprofit corporation headquartered in Lawrenceville, Georgia, that supports open source library automation software and the libraries that run on it. The organization originated as Equinox Software, Inc. in 2007 and was restructured into its current nonprofit form in 2015 to align its governance and pricing posture with its open source mission. Its product portfolio centers on two integrated library systems, Evergreen ILS and Koha ILS, supplemented by a suite of complementary modules: VuFind and Aspen Discovery for patron-facing discovery, Fulfillment for interlibrary loan, CORAL for electronic resources management, and SubjectsPlus for content management. Equinox maintains institutional membership and core-development participation across these open source communities, and its team includes both professional librarians (more than 50% of staff) and the core developers behind several of these projects.
The company generates revenue entirely through professional services under custom multi-year contracts: consulting, migration, development, hosting, support, and training, with pricing tailored to each library's size and implementation complexity. It does not license software. Customers span four verticals — public, academic, school, and special libraries — and range in scale from single-site libraries to statewide consortia (Missouri Evergreen Consortium, Evergreen Indiana, Old Colony Library Network). Distribution is consultative and direct: phone (877.OPEN.ILS), email, 'Ask Us How' website CTAs, industry conference presence, and inbound from the open source community. Recent strategic activity includes the Evergreen 3.17 release (2023) and Fulfillment 12 release (2024), alongside an expanded service menu that now includes workflow consultation, data services, web design, and IT consultation.
Equinox serves libraries in the United States and internationally, and operates a separate educational arm called equinoxEDU that produces training content and conference presentations. The organization maintains a Donate pathway and an Equinox Grants program, signaling a fundraising motion alongside its services revenue. With 11-50 employees and no equity funding, parent company, or acquisitions disclosed, Equinox is structured as a mission-driven, community-anchored nonprofit competing against commercial ILS vendors primarily on total cost of ownership, librarian-led expertise, and open source flexibility.
