FuseBase is an AI-native client portal and collaboration platform built for agencies, consultants, and other client-facing teams. Founder Paul Sher started the company in 2014 as Nimbus Note, a cross-platform note-taking app, before it grew into a full project-and-client-management suite and rebranded to FuseBase in 2023.
The platform centers on branded, no-code client portals that combine file sharing, project boards, and content workflows in one space a client can log into, rather than scattering deliverables across email, shared drives, and a separate project tool. Built-in AI agents summarize meetings, assign follow-up tasks, and automate approval steps, and the company has added support for the Model Context Protocol (MCP) to connect its AI agents to external tools.
FuseBase suits agencies and consultancies managing multiple clients who need a single branded hub rather than ad hoc file-sharing. A free plan covers one portal and one workspace with limited AI use; paid tiers start at the Solo plan for $32/month and scale through Essentials ($82/month) and Advanced ($332/month) to a custom-priced Unlimited tier, all with a 14-day trial on paid features.
