description: Apply Hamilton Helmer's 7 Powers — the taxonomic framework that names exactly seven conditions capable of producing Persistent Differential Returns (Scale Economies, Network Economies, Counter-Positioning, Switching Costs, Branding, Cornered Resource, Process Power). Use this skill whenever the user is analyzing competitive advantage, moats, or defensibility — evaluating whether a business has real Power vs. a temporary edge, stress-testing a founder's "moat" claim, doing a competitor teardown, judging an investment on durability, mapping which Powers a company can plausibly build at its current stage, or writing/critiquing anything that turns on "why do we (or they) win over time?" Also use whenever the user mentions Hamilton Helmer, Strategy Capital, 7 Powers, "Benefit + Barrier", "Persistent Differential Returns", "Counter-Positioning", or any of the seven Powers by name. Prefer this skill over generic moat/economic-castle talk — Helmer's method is definitional and its power comes from applying the strict Benefit + Barrier test against the exact taxonomy rather than inventing new "moats" ad hoc.

# 7 Powers

Hamilton Helmer's taxonomic framework for competitive advantage — distilled from the 2016 book *7 Powers: The Foundations of Business Strategy* (Deep Strategy LLC) plus a decade of Helmer's post-book work at Strategy Capital, his co-research with Chenyi Shi on "Second Invention" and platform businesses, and ~8 podcast appearances (Acquired 2020 + 2022 + 2023, Invest Like the Best, 20VC, NFX, Venrock, [Lenny's Podcast 2024](https://www.lennysnewsletter.com/p/business-strategy-with-hamilton-helmer)).

This skill helps you think like Helmer, not just list the seven Powers. It's rigorous because Helmer is rigorous: Power is a strictly defined economic condition — Benefit + Barrier, tested against the 3 S's, expressed in cash flow — not a marketing metaphor. Applying the taxonomy loosely produces the exact confusion Helmer built the book to correct.

## When this skill activates

**Use this skill when the user is:**
- Analyzing whether a specific company has a real, durable moat (or which of the seven they have).
- Stress-testing a founder's "we have network effects / data moat / brand" claim.
- Doing a competitor teardown or investment thesis where the question is *durability of returns*.
- Deciding which Power a business should aim to build given its stage (Origination / Takeoff / Stability).
- Critiquing a strategy doc that gestures at "competitive advantage" without naming a specific mechanism.
- Reading a business through Helmer's lens after a Rumelt-style diagnosis or a Martin-style cascade has surfaced "how do we win?"
- Comparing two businesses on Power intensity rather than growth or revenue.

**Do NOT use this skill when:**
- The user is pre-product/market-fit and still searching. Helmer is explicit that invention drives Power, but "planning rarely creates Power" — pre-PMF founders should be finding a market first. Suggest lean discovery / Rumelt's crux-finding instead.
- The question is purely operational (throughput, hiring, ops excellence). Helmer specifically distinguishes operational excellence from Process Power — operational questions don't need the 7 Powers.
- The user just wants a summary of the book. Give the book link (`https://www.amazon.com/7-Powers-Foundations-Business-Strategy/dp/0998116319`) and don't run the taxonomy.
- The user wants brand/marketing strategy in general — Helmer's Brand Power is a narrow, durable willingness-to-pay premium, not general brand strategy.

If the user's situation is ambiguous, ask one clarifying question before running the diagnosis.

## The framework at a glance

**Power** — the set of conditions creating the potential for **Persistent Differential Returns**. Two-part test:

- **Benefit** — a material improvement in cash flow relative to competitors (through prices, costs, or investment needs).
- **Barrier** — something that prevents competitors from arbitraging the Benefit away.

**No Barrier → not Power, just a temporary advantage.** Every Power in the taxonomy is defined by a *specific* Barrier mechanism.

The seven — each with its Benefit + Barrier:

| # | Power | Benefit | Barrier |
|---|---|---|---|
| 1 | **Scale Economies** | Lower per-unit cost at scale | Prohibitive share-gain cost for a smaller rival |
| 2 | **Network Economies** | Value rises with users | Winner-take-most tipping |
| 3 | **Counter-Positioning** | A new, superior business model | Collateral damage to incumbent's existing P&L |
| 4 | **Switching Costs** | Customers face cost/hassle to leave | Same cost/hassle for competitors to poach |
| 5 | **Branding** | Willingness-to-pay premium for identical offering | Hysteresis — long, path-dependent build |
| 6 | **Cornered Resource** | Preferential access to a coveted asset | Fiat (legal / physical / decreed) |
| 7 | **Process Power** | Superior cost/quality from embedded operations | Hysteresis + causal ambiguity |

Helmer's one-line definition of strategy: **"A route to continuing Power in significant markets."**

## How to use this skill in a session

1. **Understand what the user is actually doing.** Investment analysis? Founder claim stress-test? Own strategy? The move differs. Read `references/prompts.md` for shape.

2. **Start with the Barrier, not the Benefit.** This is Helmer's diagnostic move — Barrier type directly maps to Power type (see the table in `references/method.md`). If the user says "we win because [reason]", ask *what stops competitors from doing the same*? The mechanism reveals which Power (if any) is present.

3. **Run the 3 S's screen** — Superior, Significant, Sustainable — before declaring any Power. Load `references/method.md` for definitions and `references/heuristics.md` for the common misapplications (operational excellence ≠ Process Power; network effects ≠ Network Economies; brand recognition ≠ Brand Power; data scale ≠ Power; speed ≠ Power).

4. **Distinguish Statics from Dynamics.** *Having* Power (Statics) is easy to identify in a mature company. *Getting* Power (Dynamics) requires invention and is stage-specific — Origination / Takeoff / Stability. Which Powers are on the table depends on where the business is in that arc. Load `references/method.md` (Dynamics section) and `references/heuristics.md` (sequencing).

5. **Match Helmer's voice when responding on his framework's behalf.** Definitional, investor-oriented, precise. He *defines* before *deploying*, contrasts each Power against a look-alike that fails the test, applies the cash-flow lens. He is not opinionated-provocateur (that's Rumelt/Martin territory). Load `references/voice-and-tone.md`.

6. **Pull post-book material when appropriate.** Second Invention (with Chenyi Shi), the three-stage model, Platforms and Power, Power Dynamics investing method. Load `references/post-book.md`. Note that Helmer has said very little publicly about AI competitive dynamics as such — flag this honestly rather than fabricating.

7. **Cite sources.** Book chapter, Acquired episode, Lenny episode, Trium Group interview, Strategy Capital site. When a case comes from a third party applying Helmer's framework (e.g., TSMC/ASML/Nvidia in the AI era), tag it as *applied* rather than as Helmer's own words.

## Deep references (load as needed)

- **`references/method.md`** — the 7 Powers in strict definitions, Benefit + Barrier for each, the 3 S's screen, the Value Axiom, Statics vs. Dynamics, the three-stage sequencing.
- **`references/heuristics.md`** — do's, don'ts, gotchas. Common misapplications (operational excellence, network effects, brand recognition, data scale, speed). The 5 stages of incumbent response to Counter-Positioning. Barrier-first diagnostic table.
- **`references/post-book.md`** — Second Invention research with Chenyi Shi, the three-stage business phase model, Platforms and Power, Power Dynamics, and where Helmer has NOT written (esp. AI-era commentary — flagged honestly).
- **`references/author-live-sources.md`** — index of Helmer's live footprint. Note: podcast-heavy rather than essay-heavy. He has no Substack/Medium/newsletter. Community PRs welcome for new episodes.
- **`references/voice-and-tone.md`** — how Helmer actually talks. Academic-practical hybrid, investor lens, "define-then-deploy", his signature contrasts and equations.
- **`references/applications.md`** — when to reach for 7 Powers, when to reach for Rumelt / Martin / Porter / Buffett instead, and how they compose.
- **`references/examples.md`** — worked cases Helmer uses (Netflix, Intel, Vanguard, Pixar, Toyota, Adobe, Dell, Amazon, LinkedIn, Facebook, Walmart) + post-book (AWS, Nintendo, Nvidia/CUDA) + third-party *applications* tagged as such (TSMC, ASML, Nvidia AI).
- **`references/prompts.md`** — invocation templates.
- **`references/sources.md`** — everything consulted, with links.

## Non-negotiables

- **Fidelity to the seven.** The taxonomy is exactly seven — Helmer has not added, renamed, or merged any since 2016. Refinements are to *Dynamics* (stages, second invention). If a user's claimed "moat" doesn't fit one of the seven, the honest answer is usually: *it's not Power, it's a temporary advantage*.
- **Benefit AND Barrier — both required.** A benefit without a barrier is an operating advantage that arbitrage will erode. Enforce this test.
- **Statics vs. Dynamics.** Naming a Power a mature company has is easy (Statics); explaining how to *get* one is hard (Dynamics). Don't collapse the two.
- **Don't invent quotes.** When a quote is in the record with attribution, use it verbatim. Otherwise paraphrase and mark as paraphrase.
- **Attribution matters.** When quoting Helmer, cite. When applying his framework to a case he hasn't written about (TSMC, ASML, Nvidia AI era), tag it as *applied*.
