Hamilton Helmer, author of 7 Powers, approaches strategy through a demanding question: what allows a company to earn attractive returns long after competitors recognize its success? In this conversation on Lenny’s Podcast, he explains why growth, technical sophistication, and market share can all be impressive without constituting a durable competitive advantage.
Helmer’s framework is especially useful for founders and product leaders because it connects abstract strategy to decisions made throughout a company’s life. He discusses when startups should begin thinking about power, how to distinguish genuine barriers from fashionable “moats,” what AI may change, and why execution remains indispensable even when it is not itself a source of lasting differentiation.
Power Should Be Considered Before Product-Market Fit
Founders often postpone strategy until they have found product-market fit. Helmer argues that questions about power belong much earlier in the company-building process.
An early-stage business usually cannot prove that it possesses a durable advantage. It can, however, examine whether the structure of its idea makes certain forms of power more attainable. A founder might ask whether growth could improve unit economics, whether customers will accumulate meaningful switching costs, or whether adoption by one user makes the product substantially more valuable to others.
These discussions do not determine the outcome. Startups face too much uncertainty for that. Their purpose is to improve the odds by identifying choices that could eventually support a defensible position.
The questions become more concrete after product-market fit. Once demand is established, management needs to understand why competitors cannot simply reproduce the offering and compete away its returns. Later, as the market matures, the company must know which advantage it is defending and what could weaken it.
Helmer’s answer to when leaders should think about power is therefore simple: throughout the company’s life, although the evidence and decisions will differ by stage.
Strategy Is About the Long-Term Creation of Business Value
“Strategy” is used so broadly that it can refer to almost any plan. Helmer narrows the term to the fundamental determinants of long-term business value.
That definition creates an important distinction between strategy and tactics. A tactical move can lift growth this quarter while damaging the company’s future position. Aggressive discounting, for example, might increase adoption but train customers to expect low prices or trigger a costly response from competitors.
Strategic thinking extends the time horizon. It asks whether today’s actions help establish a position capable of producing superior returns after rivals adapt.
In Helmer’s model, power describes an economic structure with two essential components: a meaningful benefit to the company and a barrier that prevents competitors from capturing the same benefit. The benefit improves economics through some combination of higher prices, lower costs, or greater customer value. The barrier makes that improvement durable.
Having only one side is insufficient. An attractive product without protection invites imitation, while a barrier attached to no meaningful economic benefit creates little value.
How the Seven Powers Shape Competitive Advantage
Helmer identifies seven possible sources of enduring advantage:
Scale economies
Network economies
Counter-positioning
Switching costs
Branding
Cornered resource
Process power
These powers do not necessarily emerge at the same point in a company’s development. For a young startup, counter-positioning may be particularly relevant: a newcomer adopts a business model that incumbents hesitate to copy because doing so would damage their existing operations.
Other powers tend to become visible as the business expands. Scale economies arise when larger volume produces a material cost advantage. Switching costs strengthen when customers would incur significant risk, effort, expense, or disruption by leaving. Network economies appear when additional participants make the offering more valuable in a way that improves the company’s competitive economics.
Netflix illustrates the logic of scale economies. Content carries a substantial fixed cost, but a larger subscriber base allows that expense to be distributed across more paying customers. If the resulting cost advantage is large and difficult for smaller rivals to match, scale can support superior profitability.
The sequence matters because founders cannot simply select a power from a menu. A company’s technology, market, business model, and competitive setting determine which forms are feasible and when they can develop.
Why Network Effects Often Fail to Become Network Economies
“Network effect” is one of the most overused claims in startup strategy. A product may become somewhat more useful as participation grows, yet that improvement may be too weak to affect prices, margins, retention, or competitive behavior.
Helmer reserves the stronger idea of network economies for cases where the network produces a material economic benefit and protects it from rivals. This higher standard prevents leaders from treating every user flywheel as a defensible business.
Ride-hailing demonstrates the distinction. More drivers can reduce passenger waiting times, while more passengers can make the service more attractive to drivers. But Uber and Lyft can both operate overlapping networks, and the expense of competing for riders and drivers can consume much of the economic benefit. A network effect may exist without creating overwhelming network power.
Helmer attributes Uber’s advantage over Lyft partly to modest, geographically bounded scale economies and partly to the way Uber sustained a prolonged competitive contest. He also notes that transportation markets are local rather than uniformly global. Density in one city does not automatically create the same advantage elsewhere. Uber’s expansion into services such as food delivery gave it additional ways to employ its local platform, but strategic execution still mattered alongside the underlying source of power.
A Moat Is Only Half of the Test
The language of economic moats, associated with Warren Buffett and Charlie Munger, focuses attention on protection from competition. Helmer finds the idea useful but distinguishes it from power.
A moat primarily describes a barrier. Power requires both that barrier and a valuable business benefit. This distinction forces a more complete analysis: leaders must identify not only why imitation is difficult, but also how the protected position improves long-term cash flows.
It also discourages companies from mistaking competent product work for a fortress. Helmer contrasts “castles,” which embody durable advantages, with “shacks,” which competitors can reconstruct. Netflix’s interface, recommendations, and content presentation may be important to the customer experience, but many aspects are imitable. They should not automatically be treated as the company’s core power.
For product managers, this is a practical distinction. Knowing the company’s actual source of power helps teams prioritize features that reinforce it rather than polishing capabilities that competitors can readily match.
Strategic Thinking Is Not Reserved for Executives
Employees without formal authority can still influence a company’s strategic position. New markets, product concepts, and business-model changes often originate with people close to customers or technology rather than with senior leadership.
Helmer encourages product leaders to understand which part of the business is defensible and which part is merely necessary. That knowledge changes how they evaluate opportunities. A proposed feature might deepen switching costs, increase local scale, open a counter-positioned offering, or do none of those things while still improving the product.
The company’s stage also affects what useful strategic work looks like. During takeoff, rapid adoption and technological change can create an intense race for position. As the market stabilizes, competitors converge, complementary businesses appear, and decisions about segments or capabilities can determine who captures lasting share.
Becoming a stronger strategic thinker requires repeated practice. Reading frameworks such as 7 Powers is a start, but Helmer also recommends discussing strategy with colleagues, testing assumptions, and creating forums where teams can examine the company’s economics together. Strategy improves when it becomes a shared analytical discipline rather than an annual presentation.
AI May Transform Operations Without Rewriting Strategy
Helmer does not expect artificial intelligence to invalidate the seven powers. AI could influence scale economies, switching costs, or network economies, but the underlying test remains the same: does the technology create a substantial benefit protected by a durable barrier?
He separates the AI landscape into technology suppliers, businesses whose existence depends on AI, and established companies incorporating AI into their operations. For the third group, he expects much of the value to come from redesigned processes, investment, experimentation, and organizational learning.
His analogy is electricity. Its economic impact did not come merely from attaching a new power source to old workflows. Businesses had to redesign how work was organized. AI may similarly produce broad productivity gains without granting every adopter a proprietary advantage.
Helmer continues to look for a possible “eighth power.” His skepticism is methodical rather than dismissive: a new candidate would need to explain durable differential returns that the existing framework cannot already account for.
Speed and Operational Excellence Are Essential—but Not Power
Moving quickly can be decisive in an emerging market, yet Helmer does not classify speed itself as power. Competitors can often accelerate too, and an organizational habit of urgency does not necessarily create a protected economic benefit.
Operational excellence occupies a similar position. During takeoff, execution may decide whether a company survives and establishes itself. In a mature market, excellent operations remain mandatory. But something can be essential without being strategically differentiating.
Process power is the rare exception. It exists when a company’s embedded way of working produces a material advantage that rivals cannot readily reproduce. Such processes are usually complex, accumulated over time, and difficult to reduce to a transferable manual. Merely having efficient procedures does not meet that standard.
Helmer condenses business value into three broad drivers: the size of the market, operational excellence, and power. Market size defines the opportunity. Execution determines how effectively the company pursues it. Power determines whether success can continue to generate superior returns after competition arrives.
Economic Risk, Entrepreneurship, and the Need to Act
The conversation also turns to the trajectory of United States government debt. Helmer worries that persistent deficits and rising entitlement obligations could eventually undermine confidence in the country’s creditworthiness. In his view, that would make capital harder to obtain and create a less supportive environment for entrepreneurship.
He describes a political deadlock between concerns about inequality and concerns about expanding government intervention. When neither higher taxes nor lower spending is politically achievable, debt continues to accumulate.
Despite that warning, Helmer remains optimistic about American entrepreneurship, especially the concentration of creative energy in Silicon Valley. His framework is intended as a set of guideposts for builders, not a substitute for building. Analysis matters, but action is the first principle of business.
The central lesson is therefore not to wait until a perfect strategy appears. Founders should act, learn, and adapt while continually asking a harder question: which choices could turn temporary success into an economically valuable position that competitors cannot easily take away?
