SuperOps is the AI-native unified platform for modern MSPs and internal IT teams. It replaces the typical four-to-six-tool IT operations stack - PSA, RMM, helpdesk, MDM, asset tracking, network monitoring, patch management and IT documentation - with a single, built-as-one platform on a shared data layer. That architectural choice is what makes the rest of the platform work, particularly its agentic AI. Monica AI, SuperOps' intelligence layer, was designed alongside the platform from day one. It triages tickets, surfaces patch and CVE risks, drafts worklogs, suggests knowledge base articles, and increasingly handles fully autonomous workflows for routine work. SuperOps supports Windows, macOS, Linux, iOS, iPadOS and Android, integrates with the IT and MSP ecosystem (Slack, Teams, Azure AD, Okta, QuickBooks, Xero, Bitdefender, SentinelOne and more), and bundles Splashtop and ISL Online remote access free. Transparent pricing, fast deployment, founder-led product investment.
