Managed service providers built businesses on other companies’ messy software. Rewst wants to turn that sprawl into a programmable operating system - without asking every MSP to become a software company.
Nerdio builds software that automates and simplifies the deployment, management, and cost optimization of Microsoft cloud technologies - Azure Virtual Desktop, Windows 365, Microsoft 365, and Intune. Born as an internal tool at a Chicago managed service provider, Nerdio spun out in 2020 and now serves over 23,000 customers worldwide through two flagship products: Nerdio Manager for Enterprise and Nerdio Manager for MSP. In March 2025 it raised $500 million from General Atlantic at a $1 billion+ valuation.
