The lifecycle

Every product ripens. We tell you where it is.

Profit and inventory move constantly. RipeBanana turns that into one score you read at a glance — and three signals you already understand.

Greeny, the green banana
Ripening

Opportunity forming

Early and promising. Greeny flags where there’s still room to buy smart and move first.

Ripely, the yellow banana
Ripe

Peak — act now

Profit is high and stock is thinning. Ripely marks the exact window to buy before it closes.

Brownie, the brown banana
Rotten

Value gone

The window passed. Brownie makes the cost of waiting visible, so it doesn’t repeat.

Opportunities

A ranked feed of what’s ripe to buy.

Every product that crosses into ripe, sorted by ROI and how fast inventory is thinning. Stop scanning spreadsheets — start with the ones that pay.
