FuseBase review and pricing

Knowledge-base-anchored client portal with embedded docs, wikis, and collaboration.

By FuseBase (formerly Nimbus) · Founded 2015 · Wilmington, DE · private

FuseBase rebranded from Nimbus Platform in 2023, repositioning a long-running knowledge-base and note-taking product (Nimbus Note) into a client-portal-plus-docs platform. The product merges what would otherwise be two systems (a wiki or knowledge base plus a client portal) into one workspace. Wins on the depth of the embedded document editor, the breadth of templates inherited from the Nimbus content stack, and lifetime-deal pricing history that built a loyal SMB base. Loses on brand confusion from the rebrand, integration depth versus Moxo, and a strategy that sometimes feels split between knowledge-base and portal use cases.
