What is BigTime?

BigTime's changelog is an SEO content mill — no product signal reaches it.

Every recent entry on this feed is a ranked buyer's guide or category explainer: billing software, construction financial management, resource management, engineering accounting, architecture project management, time tracking. The content is written for search intent around professional services billing and revenue leakage, and it names BigTime only in passing. No release notes, version numbers, or feature announcements appear anywhere in the last ten entries.

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.

BigTime vs Tability: editorial side-by-side

B5.0

BigTime's changelog is an SEO content mill — no product signal reaches it.

◆ Current state

Every recent entry on this feed is a ranked buyer's guide or category explainer: billing software, construction financial management, resource management, engineering accounting, architecture project management, time tracking. The content is written for search intent around professional services billing and revenue leakage, and it names BigTime only in passing. No release notes, version numbers, or feature announcements appear anywhere in the last ten entries.

◆ Where it's heading

The feed is a marketing channel, so its cadence tracks the content calendar rather than the product — three posts on 11 August, three on 16 July. Reading product direction from it is not possible: the only recurring theme is the revenue-leakage argument BigTime uses to sell PSA, restated per vertical.

◆ Prediction

Expect more vertical buyer's guides on the same schedule. Actual product signal will have to come from a release-notes source, which this feed is not.

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.
