About BlitzLab
BlitzLab is a research project that scores companies on their blitzscaling strategy — how concentrated capital seizes a category, and whether the moat lasts. We call it the credit rater for blitzscaling.
What we do
Every quarter we judge each covered company against the same 100-point ruler, the Blitz Index, using published filings and reported data. The current universe is 83 scored companies, and every scorecard is public: score, grade, the item-by-item breakdown, the reasoning, and the score history. We also publish our failures: companies that never made it through the gates get a judgment file explaining exactly why.
How the score works (Blitz Index v1.0, frozen)
The model is frozen at version 1.0. Weights, thresholds, and the qualitative anchors are not quietly changed. Two gates must both pass before any scoring begins:
- Gate 1 — the business is real: product-market-fit evidence (for mature companies, sustained growth or a second growth curve)
- Gate 2 — there is room: a 10-year market ceiling at least 10× current revenue
Then the 100 points:
| Section | Points | What it measures |
|---|---|---|
| A · Speed | 25 | Revenue growth, capital-raising pace, hiring/productivity, market-share movement |
| B · Moat | 60 | Network effects, distribution scalability, market size, gross margin |
| C · Creative destruction | 15 | What old order is being replaced, irreversible behavior change, cost-structure disruption |
| D · BlitzFailing demerits | up to −30 | Debt and interest, revenue quality, governance, regulatory and social cost |
Grades: S ≥ 90 · A ≥ 80 · B 60–79 · C 40–59 · D < 40. The success line is 65, set by a 20-company blind backtest (the first draft's 80 was lowered after measurement). A total demerit of −15 or more flags the company for BlitzFailing watch — currently SMCI, CVNA, and EOSE.
The full methodology is published in the Blitz Index methodology PDF.
What the score is not
This is the part we consider the most important. We ran pre-registered hypotheses testing whether the score predicts stock returns — all three were rejected: crossing the 65 line, profitability turns, and score slope showed no predictive power. Our conclusion, published in the research series: the score measures business quality; entry price governs returns. BlitzLab is not investment advice. We publish no buy/sell recommendations, no price targets, no implied returns. Expectations and concerns are both stated for every company.
Data and process
- Primary source is SEC EDGAR filings — companies' own reported numbers, checked against press-reported figures when filings are thin.
- We re-score after each quarterly earnings report; past scores are never silently rewritten. Arithmetic errors, when found, are corrected with a public correction note.
- Uncertainty is labeled, always: confirmed, estimated, press-reported, or unconfirmed.
- Unlisted companies are scored as ranges (e.g. 51–68) with lower confidence and press-reported data — the score is not adjusted for low confidence; the confidence is shown separately.
Coverage
83 companies scored as of 2026Q4, plus 12 gate rejections published with judgment files (for example SPOT, MU, ARM, BMNR, XYZ, and TEAM). The research series documents the model's limits in the open — including the validation work that rejected our own hypotheses.
