Multi-business portfolios create value in exactly three places: revenue synergies, cost synergies, and capability transfer. They destroy value in one: coordination tax. This tool lets you plot your business units on a two-axis canvas and draw the directional links between them — so you can see at a glance where the portfolio earns its keep and where it's secretly subsidizing itself.
Synergy Mapper
Visualize the hidden value in your portfolio.
An interactive tool for mapping the synergies and friction between your business units. Define your portfolio, tag shared customers, shared technology, and shared capabilities, then see an auto-generated analysis of where value is being created or destroyed.
How to use this tool
Start by adding your business units (3–8 recommended). Then for each pair, indicate whether they share customers, technology, or capabilities — and where there is friction or duplication. The mapper generates a synergy heat map and prioritized recommendations.
Step 1: Define Your Business Units
Add 3-8 business units, product lines, or divisions to map. These will form the nodes of your synergy analysis.

How to read a synergy map
A useful synergy map surfaces three patterns. First, the lopsided donor— a unit that contributes capabilities, talent, or brand to several others but receives little in return. If the contribution isn't economically priced, that unit is quietly underperforming on paper.
Second, the disconnected node— a unit with few or weak links to the rest of the portfolio. Sometimes that's a feature (a real option, an experimental bet); more often it's a candidate for divestiture.
Third, the friction cluster— units where the links are negative: shared customers cannibalize, shared channels compete, shared brand confuses. Friction clusters don't get better on their own.
From map to decision
A synergy map by itself is a diagnostic, not a decision. Use it as input to three conversations: portfolio strategy (what to keep, what to fix, what to sell), operating model (what to centralize vs. federate), and incentives (how to price inter-unit contributions so the math rewards the behavior you want). The BCG Growth-Share Matrix and the portfolio strategy anatomy pair naturally with this tool.
When to revisit
Synergy maps go stale fast. Re-map at least annually, any time you complete a material acquisition or divestiture, and whenever a new CEO takes over a business unit. Save a PNG export as part of your board prep — the visual does more for conviction than any spreadsheet.
