ICAERUS Market Structure App

Analyse market concentration (CR, HHI) for multiple Key Exploitable Results or segments within a project. Each KER/segment is treated as a separate market; residual firms can be modelled as uniform or Pareto-distributed.

1. Configure current segment / KER

Segment / KER name Unit used (€, units, ha, users, etc.) Total market size (in chosen unit) Estimated total number of firms in this segment

Market boundary description (optional)

Residual distribution model

Pareto α (shape)

Pareto α controls how unequal residual firms are.
Default 1.5 ≈ typical "80-20 style".

2. Enter main firms for this segment

Use the same unit as the total market above. Add the main firms you know (ideally the largest ones). Residual firms will be modelled collectively using the selected distribution.

Firm Name	Sales / Volume	Remove

3. Porter 5 Forces inputs (user judgment)

Supplier power Low: many suppliers, easy to switch. High: few critical suppliers, strong IP or data control.

Buyer power High: buyers concentrated or can switch easily. Low: fragmented buyers, higher switching cost.

Threat of substitutes High: alternative ways to solve the same problem (traditional or other tech).

4. Calculate metrics and narrative for this segment
