What is 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.

What is Sugar Calendar?

Events can finally ask attendees a question at the moment they sign up.

Registration Forms arrive as a tab on the event itself: a small builder with five field types — short text, long text, multiple choice, checkboxes and dropdown — each markable as required, asked at ticket checkout or on the RSVP form, with the answer landing on the attendee's record beside their name and ticket. The post is explicit that this collapses two separate requests, custom fields on checkout and custom fields on RSVP, into one feature. It follows a run of releases that added attendee email, Elementor page design, per-event ticket pricing and Zoom links.

Nimbus vs Sugar Calendar: editorial side-by-side

N5.0

FuseBase is pivoting into AI app building while its marketing still sells the old portal category.

◆ Current state

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.

◆ Where it's heading

The company is moving from a place to store documents and client files toward a place where agents build software, and the Flow launch states it most plainly — phases, slices, reviews and gates imposed on AI-generated projects instead of one overloaded chat. The target is client-facing businesses that want to ship applications without an engineering team. Marketing has not followed the product: every recent post still chases buyers shopping for a Notion or Quip replacement.

◆ Prediction

Expect the next real releases to keep hardening the AI Coding path — more structure around review, stability and deployment — since that is where every product post in this window concentrates. Whether the listicle engine ever repoints at the AI positioning is unresolved; right now the two halves of this feed address different buyers.

S5.0

Events can finally ask attendees a question at the moment they sign up.

◆ Current state

Registration Forms arrive as a tab on the event itself: a small builder with five field types — short text, long text, multiple choice, checkboxes and dropdown — each markable as required, asked at ticket checkout or on the RSVP form, with the answer landing on the attendee's record beside their name and ticket. The post is explicit that this collapses two separate requests, custom fields on checkout and custom fields on RSVP, into one feature. It follows a run of releases that added attendee email, Elementor page design, per-event ticket pricing and Zoom links.

◆ Where it's heading

Every release this quarter has removed one thing an organiser previously did outside the plugin — the follow-up email, the page builder, the pricing spreadsheet, the Zoom link, and now the post-signup questionnaire and the spreadsheet of answers that went stale on the first cancellation. The pattern is consistent enough to read as a deliberate sweep of the manual work around an event rather than a feature roadmap. Each arrives as a how-to titled post rather than a release note.

◆ Prediction

Answers now sit on the attendee record, so the next obvious step is doing something with them in bulk — filtering or exporting attendees by response, or segmenting the follow-up email by answer. The post stops at collection.
