iThemes Hosting was a managed WordPress hosting product powered by Liquid Web infrastructure. Liquid Web acquired iThemes in January 2018. The hosting product launched later that year but was subsequently discontinued as customers were funneled into Liquid Web and Nexcess managed WordPress plans. The iThemes brand was rebranded to SolidWP, which now focuses exclusively on WordPress security and backup plugins (Solid Security, Solid Backups). No hosting product remains.
This entity exists for reference. Former iThemes Hosting customers are now on Liquid Web infrastructure.
