BCG Matrix Maker

Plot your products or business units on the growth-share matrix — market growth up the Y-axis, relative market share across the X — and Gixo Prism places each one into the exact quadrant: star, cash cow, question mark, or dog. You supply the market data; Prism structures it into the framework, deterministically, with no gridlines to draw and no labels to drag.

The BCG matrix — also called the growth-share matrix or Boston matrix — is a 2x2 that plots a company's products or business units on two axes: market growth rate (vertical) and relative market share (horizontal). The four quadrants are stars (high growth, high share), cash cows (low growth, high share), question marks (high growth, low share), and dogs (low growth, low share). In Gixo Prism you enter each item with its growth and share position, and Prism places it into the exact quadrant deterministically — no AI image model in the loop, so every label lands where the data puts it. You supply the market figures; Prism structures them into the framework.

The four BCG categories

Every product lands in one of four quadrants, defined by where it sits on market growth and relative market share.

Stars — high growth, high share

Market leaders in fast-growing markets. They usually consume cash to hold position, but are the businesses most likely to become tomorrow's cash cows as growth slows.

Cash cows — low growth, high share

Leaders in mature, slow-growing markets. They generate more cash than they need, funding stars and question marks elsewhere in the portfolio.

Question marks — high growth, low share

Small players in fast-growing markets. They need heavy investment to gain share and could become stars — or drain cash and slide into dogs.

Dogs — low growth, low share

Low-share products in slow-growing markets. They rarely generate much cash and are often candidates to hold, harvest, or divest.

Exact quadrant placement

No AI image model draws this grid. Prism renders the matrix geometry deterministically, so each item lands in the exact quadrant your growth and share figures put it — no garbled text, no drifted gridlines.

Brand-palette governance

Apply your brand palette to the matrix and it stays consistent with every other chart and diagram you build in Prism, plus theme presets to start from.

How do you make a BCG matrix with Gixo Prism?

Four steps from a portfolio spreadsheet to an exact, on-brand growth-share matrix.

1
Gather your market data

For each product or unit, note its market growth rate and its relative market share (share vs. your largest competitor). You supply these figures.

2
Enter each item with its position

Add each product with its growth and share values so Prism knows which quadrant it belongs in — star, cash cow, question mark, or dog.

3
Prism structures the matrix

The 2x2 geometry places your axis labels and each item into the exact quadrant automatically — no manual gridline drawing, no dragging labels into place.

4
Apply your theme and export

Pick a theme preset or your Brand Kit, then export the matrix as clean HTML/SVG for your strategy deck, board doc, or page.

Frequently Asked Questions

What is a BCG matrix?
The BCG matrix — also called the growth-share matrix or Boston matrix — is a portfolio framework developed by the Boston Consulting Group. It's a 2x2 that plots products or business units on market growth rate (vertical) versus relative market share (horizontal), sorting them into four quadrants: stars, cash cows, question marks, and dogs.
What are the four quadrants of the BCG matrix?
Stars (high growth, high share), cash cows (low growth, high share), question marks (high growth, low share), and dogs (low growth, low share). Stars often become cash cows as markets mature; question marks need investment to become stars or risk becoming dogs.
Does Gixo Prism calculate the quadrants for me?
Prism structures your inputs into the framework — you supply each item's market growth and relative market share, and it places each one into the exact quadrant deterministically. It doesn't source or verify your market figures; those are yours to provide and review.
How do I calculate relative market share?
Relative market share is usually your product's market share divided by that of your largest competitor. A value above 1.0 means you lead the market; below 1.0 means you trail it. You compute these figures from your own market data and enter them into Prism.
What formats can I export?
The matrix and every other diagram geometry export as clean, self-contained HTML/SVG you can drop into a deck, doc, or page. There's no PDF or PPTX export from the diagram maker.
Can I edit the matrix after generating it?
Yes. Update a product's growth or share figures, add or remove items, or apply a different theme, and the matrix re-renders exactly — no redrawing gridlines by hand.
How much does it cost?
There's a 14-day free trial with no credit card. After that, Gixo Prism is $19/month with everything included.
