About Nimbus
FuseBase is pivoting into AI app building while its marketing still sells the old portal category.
The feed tracked here is thefusebase.com — the product trades as FuseBase now — and it carries two unrelated streams. The recent half is competitor-alternative SEO (Quip, Google Docs, Notion Sites, Clinked, Moxo) selling the collaboration and client-portal positioning. The product half, all from May and June, is about something else: FuseBase Flow, FuseBase AI Apps, and an AI Coding module for turning ideas into shippable applications.
