Solus is privately owned by its founders.

Breeding, Marshall. SOLUS Expands through Acquisition of Boopsie. November 2020. Smart Libraries Newsletter. SOLUS has acquired the Boopsie Mobile division from Demco, Inc. The deal strengthens SOLUS's presence in the global library market. Boopsie was one of the pioneers of mobile technology in libraries, though its presence has since been eclipsed by SOLUS and other providers. The technology platform developed by Boopsie was quite advanced and forward-looking when it was launched in 2005, though it may not necessarily be optimal for the current generation of patron-facing mobile interfaces. This business event provides libraries using Boopsie's products an opportunity to shift to more recently developed technologies provided by a vendor with established success in the library mobile technology sector. While consistent with the pattern of consolidation within a market niche, it runs a bit counter to the trend for smaller specialized companies to be acquired by large businesses with diverse product portfolios.
