Memory Triggers
Tiny cues. They reconstruct big topics.
Define a startup
Steve Blank: temporary org searching for repeatable, scalable, profitable model.
Three pillars
Innovation × Scalability × Structured Uncertainty (jointly necessary).
Four phases
Idea→Hypothesis | Problem-Solution Fit | PMF | Go-To-Market.
FOMO vs FOLS
Emotional pull vs rational brake. Act I + Act II of pitch.
3C
Convergence, Connectedness, Context — trend-spotting.
Hype Cycle stages
Trigger → Peak → Trough → Slope → Plateau. Slope = sweet spot.
Hexagon six formulas
X^d (Generalize), X+Y (Fusion), X↑ (Nails), X↓ (Hammers), X++ (Adjective), X̄ (Opposite).
Oxygen Test
Would anyone struggle to breathe if it vanished? Binary, no appeal.
Five Filters
Problem, Market, Solution, Team, Business Model. Each is a veto.
35%
Of startups die from no market need (CB Insights). Why the Oxygen Test exists.
Levine's Law
Fall in love with the problem, not the solution. Tree: Product → Solution → Problem (root).
5Ws
Who, What, When, Where, Why. Why = keystone.
Seven stakeholder roles
Decision Maker, Influencer, Buyer, Manager, Operator/User, Evaluator, CFO.
Painkiller test
High Frequency + High Magnitude = Urgent Problem. Vitamin if either is low.
Bias is the enemy of validation
Survey design rule. Past behaviour > hypothetical future. Quantify pain.
Old Map vs New Compass
Traditional linear product dev vs Customer Development loop with pivot arrows.
Four stages of Customer Development
Discovery (Problem-Solution Fit) → Validation (PMF) → Creation (scale demand) → Building (scale org).
Six hypothesis types
Product, Customer/Problem, Distribution/Pricing, Demand Creation, Market Type, Competitive.
Hypothesis formula
My idea solves [problem] by [solution]. Narrow + emotional pain explicit.
Detective Phase four questions
Tell me how you currently do X / How is that working / What's the hardest part / If you could improve anything…
Validation Board
Track pivots (up to 4). Design experiments (riskiest assumption). Results: validated/invalidated.
BML loop
IDEA → BUILD (MVP) → MEASURE → LEARN → (Persevere or Pivot) → IDEA.
MVP three letters
Minimum (smallest), Viable (actually works), Product (any artefact — landing page, mock, prototype, software).
Earlyvangelist Pyramid
Five tiers: You-know they have problem | They know | Looking | Hacking workaround | Have budget. First customers at the apex.
Market pulls (PMF)
Andreessen: in a great market, market pulls product out of startup. Direction-of-force reversal.
Value Hypothesis (Tren Griffin)
Three deliverables: features, audience, business model.
Experience Economy ladder
Commodity → Goods → Service → Experience → Transformation. Higher rung = more value, more price.
Value equation
Customer Value = Value Created − Price; Marketer Value = Price − Cost; Total = Value Created − Cost.
Next Best Alternative
Pricing principle: value is always relative to NBA. Price = value above NBA, capped by willingness to pay.
VPC six slots in order
Customer first: 1 Jobs, 2 Pains, 3 Gains. Then VP: 4 Products & Services, 5 Pain Relievers, 6 Gain Creators.
Christensen on VP
VP helps customers do more effectively, affordably, conveniently a job they've been trying to do.
10 characteristics of great VP — top two
#4 narrow (few jobs done extremely well). #9 substantially differentiated on at least one dimension.
BMC nine blocks
Front Stage (CS, CR, CH) | VP centre | Back Stage (KR, KA, KP) | Box Office (CS$, RS$). Nine blocks, three zones, one bridge.
BMC viability equation
Inflow > Outflow. Revenue Streams must exceed Cost Structure.
Lean Canvas four substitutions
Key Partners → Problem; Key Activities → Solution; Key Resources → Key Metrics; Customer Relationships → Unfair Advantage.
Riskiest Assumption
The block that would kill the business if wrong. Test it first with a cheap MVP.
STP three verbs
Identify (Segment), Determine (Target), Create (Position).
Five-petal flower
Segmentation diagram: overlapping segments at intersection of value bring. Up to 5 most compelling.
AHA Grid four quadrants
Benefits × Price. Top-left Contenders (disruption sweet spot), Top-right Leaders, Bottom-left Laggards, Bottom-right Challengers.
USP Defensibility ladder
T1 Cannot be imitated (patents) | T2 Difficult (brand, network) | T3 At a cost | T4 Easy (commodity). Aim for T1/T2.
SWOT axes
Internal vs External × Helpful vs Harmful. Weakness internal; Threat external — don't confuse.
SWOT connections
SO/ST/WO/WT cross-quadrant moves. At least one explicit on the exam.
Find Your USP four zones
Winning (Brand × Consumer, not Comp) ✅ | Risky (all three) ❓ go emotional | Losing (Consumer × Comp, not Brand) ❌ | Who Cares (Brand × Comp, no Consumer) — wasted energy.
4P marketing mix
Price, Product, Promotion, Place. STP feeds the 4Ps.
Cross-phase #1
VPC is a zoom into BMC's Customer Segments + Value Proposition blocks. Nested, not alternative.
Cross-phase #2
BMC = hypotheses. Validation Board = scoreboard. BML = the game.
Cross-phase #3
5Ws Who → BMC Customer Segments → STP Segmentation → AHA Grid axes. One identity, four labels.
Cross-phase #4
Painkiller (Phase 2) + Contenders quadrant (Phase 4 AHA) = the defensible startup recipe.
