Strategy

Product-Market Fit is the degree to which your product satisfies a strong market demand. When you have PMF, customers are actively pulling your product from you rather than you pushing it onto them. Marc Andreessen defined it as 'being in a good market with a product that can satisfy that market.' The Sean Ellis test quantifies it: if 40%+ of users say they'd be 'very disappointed' without your product, you have PMF. Before PMF, nothing else matters — marketing spend is wasted, hiring is premature, and features are guesses. After PMF, everything gets easier: organic growth appears, retention improves, and word-of-mouth starts compounding.

PMF Score = % of users who'd be 'very disappointed' without your product (target: ≥40%)

Pricing strategy determines how much you charge customers and directly impacts revenue, positioning, and perceived value. The three primary approaches: (1) Cost-Plus: price = cost + margin (lazy, leaves money on the table). (2) Competitor-Based: match or undercut competitors (race to the bottom). (3) Value-Based: charge 10-20% of the value you create for the customer (optimal). If your product saves a customer $50,000/year, charging $5,000/year (10% of value) is the sweet spot. The customer gets 10x ROI, and you capture meaningful revenue. Pricing is the fastest lever for revenue growth — a 1% price increase typically adds 11% to profits.

Optimal Price ≈ 10–20% of the $ value your product creates for the customer

A competitive moat is a durable advantage that protects your business from competitors, just like a castle moat keeps invaders out. Warren Buffett popularized the term: he only invests in companies with 'wide moats.' The 5 types are: network effects, switching costs, brand, cost advantages, and proprietary technology. Companies with strong moats earn 20%+ returns on capital vs 8-10% for those without.

Moat Strength = Switching Cost ÷ Annual Subscription Value

Total Addressable Market is the total revenue opportunity for your product if you achieved 100% market share. It's broken into three layers: TAM (total market), SAM (Serviceable Addressable Market — the segment you can reach), and SOM (Serviceable Obtainable Market — what you can realistically capture). Investors use TAM to assess if a market is worth entering. VCs typically want a $1B+ TAM to justify their fund economics.

Bottom-Up TAM = Number of Target Customers × Annual Contract Value

A Go-To-Market (GTM) strategy is the plan for how you'll reach, acquire, and serve customers profitably. It answers three questions: WHO is your ideal customer? HOW will you reach them? WHY will they choose you over alternatives? There are three dominant GTM motions: Sales-Led (Salesforce, $80K+ ACV), Product-Led (Slack, Figma, <$1K ACV self-serve), and Channel-Led (Microsoft through resellers). Choosing the wrong motion for your price point and buyer is the #1 reason startups stall at $1-5M ARR.

GTM Efficiency = Net New ARR ÷ (Sales + Marketing Spend)

A network effect occurs when a product becomes more valuable as more people use it. Metcalfe's Law states that the value of a network grows proportional to the square of its users (V ∝ n²). A phone network with 10 users has 45 possible connections; with 100 users, it has 4,950. This creates a virtuous cycle: more users → more value → more users. Facebook, Uber, Airbnb, and LinkedIn all built trillion-dollar businesses primarily through network effects. There are 4 types: Direct (WhatsApp — more users = more people to message), Indirect/Two-Sided (Uber — more riders attract more drivers and vice versa), Data (Google — more searches = better results), and Platform (iOS — more users attract more app developers).

Metcalfe's Law: Network Value ∝ n² (where n = number of users)

The Flywheel Effect, coined by Jim Collins in 'Good to Great,' describes a self-reinforcing growth loop where each component accelerates the next, building unstoppable momentum over time. Amazon's flywheel: lower prices → more customers → more sellers → greater scale → lower costs → even lower prices. Each turn of the flywheel makes the next turn easier. Amazon grew 27% annually for 20 years not from any single initiative, but because every investment strengthened the flywheel. The key insight: flywheels are HARD to start (the first few turns require enormous effort) but nearly impossible to stop once spinning.

Switching costs are the barriers (financial, procedural, emotional) that make it expensive or difficult for a customer to switch to a competitor. Higher switching costs = higher retention and pricing power. There are 4 types: Financial (Salesforce's $10K+ migration cost), Procedural (retraining 200 employees on a new CRM takes 6 months), Data (your 5 years of Slack messages are trapped), and Emotional (brand loyalty, familiarity). Apple's ecosystem has all four: $2,000+ in repurchased apps, learning a new OS, losing iMessage/AirDrop interoperability, and identity attachment. This is why Apple's iPhone retention rate exceeds 92%.

Total Switching Cost = Migration Cost + Retraining Cost + Productivity Loss + Data Migration Risk

Positioning is the deliberate act of defining how your product is perceived in the minds of your target customers compared to alternatives. It dictates your obvious ideal customer, the specific problem you solve, and why you are clearly better than the status quo.

The Business Model Canvas is a strategic management template that visualizes the fundamental building blocks of a business on a single page. It explicitly connects your Value Proposition (what you sell) with your Customer Segments (who you sell it to), backed by the operational and financial structures required to deliver it.

Freemium is a business model where the core product is offered completely free to amass a massive user base, while premium functionality, advanced features, or usage limits are gated behind a paid subscription. It acts simultaneously as a product strategy and a top-of-funnel customer acquisition channel.

Freemium Viability = (CAC of Free User + Cost to Serve Free User) < (LTV of Paid User × Conversion Rate)

Land and Expand is a B2B sales motion where you sell a small, low-friction deal to a single user or small team within a large organization (the 'land'). Once value is proven, you systematically upsell more seats, higher tiers, or cross-sell to other departments (the 'expand'). This strategy bypasses slow, top-down enterprise procurement cycles.

Net Revenue Retention (NRR) = (Starting MRR + Expansion MRR - Contraction MRR - Churned MRR) / Starting MRR

A pivot is a structured course correction designed to test a new fundamental hypothesis about the product, strategy, or engine of growth, while keeping one foot rooted in what you've learned. It is not a random, desperate change of direction; it is a calculated turn when the data proves your current path leads to a dead end.

Blue Ocean Strategy is the simultaneous pursuit of differentiation and low cost to open up a new market space and create new demand. Instead of competing head-to-head in existing, crowded industries (Red Oceans) where competitors fight for a shrinking profit pool, you make the competition irrelevant by creating undisputed market space.

Porter's Five Forces is a framework that proves industry profitability is not determined by the product, but by the structure of the market. It dictates that your margins are constantly under attack from five directions: Existing Rivals, Powerful Suppliers, Powerful Buyers, Substitute Products, and New Entrants. If all five forces are strong, nobody makes money.

Economies of scale occur when a company's per-unit cost of production decreases as its volume of output increases. When you possess massive fixed infrastructure—like a global logistics network or complex software code—scaling your customer base allows you to spread those fixed costs over millions of units. This generates an unbeatable structural cost advantage over smaller rivals.

Unit Cost = (Total Fixed Costs ÷ Total Volume) + Variable Cost Per Unit
