Meets your team where they already work.

Herfindahl is built for the realities of how economic consulting teams work. The goal isn’t to replace your toolchain—it’s to make your workstreams faster and more reliable.

High-stakes analysis fails in predictable ways.

Speed without control creates risk.

Under deadline pressure, small mistakes compound: wrong joins, stale inputs, inconsistent rounding, accidental overwrites.

Under tight deadlines, review often slips.

Traditional review is manual and time-consuming, and still often misses silent failures.

Keep a clear line of sight. Turn opaque workstreams into something you can explain, review, and sign off.

Produce results faster with fewer surprises. Reduce rework by surfacing problems earlier.

Protect confidentiality without slowing down. Keep control over where data lives and how inference is routed.

Built for economic consulting teams.

Herfindahl is designed around how economic consulting teams actually work. It makes the workstream legible, helps case teams move faster, and surfaces silent errors before they become deliverable risks—while keeping humans in control of what runs and what changes.

Workspace

Your case, organized. Make scripts, data, and outputs legible—so review and sign-off are easier to manage.

Agent

An analyst who can act. Inspect data, review code, and help execute work—always permissioned, always reviewable.

Analysis assumptions

Data selection
- The analysis calculates market shares for Micron and Samsung based on sales volumes aggregated at the annual level (summing across all quarters within each year).
- Market share calculations include only two specific node ranges: 16-28nm and 45-65nm. Other node ranges (e.g., 7-14nm, 90nm+, Sub-5nm) are excluded from this analysis.
- Sales volumes are measured in millions of 8-inch equivalent wafers. The analysis assumes the wafer_equivalent_inch conversions in the cleaned data are correct.
Transformation
- Total market sales for each node range include all companies in the dataset, not just Micron and Samsung. The total market is calculated first, then filtered to show only Micron and Samsung shares.
Modeling choice
- The analysis uses volume-based market shares rather than revenue-based shares.

Audit

Double-blind replication for every single result. Compare deterministically and document assumptions before anything leaves the room.

Double-blind replication, built in.

For the highest-stakes deliverables. Herfindahl can independently reproduce results from the underlying inputs before looking at the original analysis. It can compare outputs deterministically, surfaces discrepancies clearly, and documents issues and assumptions—so errors don’t survive into client deliverables.

From case folder to client deliverable.

Notes

Wafer size conversion: 12-inch wafers are converted to 8-inch wafer equivalents using an area-based ratio of 2.25:1 (based on (12/8)² = 2.25).

Capacity-to-sales comparison: Monthly capacity figures (in wafers per month) are annualized by multiplying by 12 to compare directly against annual global sales volumes.

Built for enterprise deployment.

Herfindahl is designed so organizations can retain end-to-end control of their data. Run Herfindahl locally on your machines, and route LLM inference through custom infrastructure to meet the highest confidentiality requirements.
