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 Tability?

Tability is building the org graph its AI agents will need to act on.

Tability is an OKR and strategy platform that has spent 2026 turning a plan hierarchy into a queryable graph. The Strategy Map now organises by people as well as plans, the Dependencies Map traverses up to parent context and down through downstream work from any object, and a workspace-wide filtering layer with saved segments sits over goals and initiatives. Running alongside is an agent track: an AI Importer that reads OKR and KPI spreadsheets into reviewable proposals, and AI managers that can be assigned to a goal and must route decisions back through an approval flow.

Nimbus vs Tability: 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.

T7.5

Tability is building the org graph its AI agents will need to act on.

◆ Current state

Tability is an OKR and strategy platform that has spent 2026 turning a plan hierarchy into a queryable graph. The Strategy Map now organises by people as well as plans, the Dependencies Map traverses up to parent context and down through downstream work from any object, and a workspace-wide filtering layer with saved segments sits over goals and initiatives. Running alongside is an agent track: an AI Importer that reads OKR and KPI spreadsheets into reviewable proposals, and AI managers that can be assigned to a goal and must route decisions back through an approval flow.

◆ Where it's heading

The two tracks are converging, and the sequencing tells the story. Delegating goals to AI agents shipped first; the releases since have been building the structure those agents need to reason over — who reports to whom, what depends on what, which slice of a busy workspace a question is actually about. Overflow controls on large maps and a refreshed Initiatives view point at customers with enough plans and people for readability to become the constraint, which is a different buyer than the small-team OKR tool this category started as. Import friction is being attacked from the same direction: an AI-assisted path out of spreadsheets, with review gates before anything is created.

◆ Prediction

Expect the agent features to start consuming the graph the recent releases exposed — dependency-aware and reporting-line-aware agent actions rather than per-goal delegation — and the scheduled-prompt mechanism behind executive summaries to widen into other recurring outputs.
