Ugg hunt the mammoth FIRST, then make the spear

Foolish caveman make the spear first, THEN look for the mammoth. Sometimes no mammoth — spear wasted, tribe hungry. Smart way: find the mammoth first. That is Phase 3 — one job: hunt down a business model that is REAL, one that survives meeting real tribe-folk.

Two wise elders teach this. Steve Blank give us Customer Development — the way to hunt for how-tribe-make-food. And Eric Ries give us Lean Startup and the Build-Measure-Learn fire-loop. A business model is just: how tribe make shiny stones. Fancy elders say "how you create, deliver, and capture value" — same thing: get food, keep some.

Old map bad, new nose good

Old caveman follow the Old Map — one straight line scratched on the cave wall:

He think he already KNOW what tribe want. Big danger — he build thing nobody want.

Smart caveman use the New Compass — a loop, sniff-sniff, follow footprints:

When the tracks say wrong way, caveman pivot — turn around, go back to Discovery. Remember the one big lesson: Old Map executes a plan; New Compass discovers a model.

Four camps, two halves, one gate

Steve Blank draw four camps you walk through:

• Customer Discovery — "Is my guess about the tribe's problem right?" Win here = Problem-Solution Fit (the pain is real, my idea touches the pain).
• Customer Validation — "Did I make a thing tribe actually USE and PAY shiny stones for?" Win here = Product-Market Fit (PMF).
• Customer Creation — "Can I make MANY tribe want it?" (grow the crowd)
• Company Building — "Can my little hunt-party become a steady tribe?"

Ugg warn: Problem-Solution Fit is NOT Product-Market Fit! First you learn the pain is real; LATER you learn people pay. Two rocks, in ORDER. Foolish caveman beat chest "I have PMF!" holding only the first rock. Fire-god sees the lie.

First two camps = Search (pivot allowed; wander to find good hunting ground). Last two = Execute (animals are here, so dig in and grow). The line between them is Product-Market Fit:

Ugg warn LOUD: do NOT build a giant camp before you find the mammoth! Grow big before PMF and you just make the same leak bigger — spend all shiny stones, tribe starves. That is the number-one way tribes burn money. PMF is the gate. Carve on your spear: No business plan survives first contact with customers.

Six guesses and one magic sentence

Before you talk to anyone, write six kinds of guess (hypotheses):(1) Product,(2) Customer & Problem,(3) Distribution & Pricing,(4) Demand Creation,(5) Market Type,(6) Competitive. Test all six later — don't write six then forget four.

Then squeeze each into the Hypothesis Formula:

Ugg warn: name the REAL hurt, not the boring action. Bad: "solves the need to do laundry." Good: "solves the inconvenience and big time-eating of clean laundry by 24-hour delivery." Narrow, sharp, name the feeling.

Be the detective, hide your spear

The hard rule that fights every caveman's gut — the Detective Phase:

Your goal is NOT to ask the tribe what they think of your idea. It is to find and validate their needs WITHOUT showing your solution.

Do not wave your shiny spear and shout "you like?" Tribe-friends lie to be nice, and lies are bad meat. You are a detective hunting footprints of the problem — shut mouth, LISTEN, let the tribe build the thing for you. Four detective questions, all about what they do NOW (never dream-future):

• "Tell me how you currently do ____."
• "How is that working for you?"
• "What's the hardest part about ____?"
• "If you could improve anything about ____, what would it be?"

Scratch the scoreboard — the Validation Board

The Validation Board is a flat rock where you track the hunt like a wise shaman. Four zones:

• Track Pivots — rows (Customer, Problem, Solution guess) and columns (Start, 1st, 2nd, 3rd, 4th Pivot). You get up to four pivots before you earn the right to quit.
• Design Experiments — list every leap-of-faith, then circle the Riskiest Assumption (the one guess that, if wrong, kills the tribe FASTEST), the Method (a cheap test), and the Minimum Success Criterion (the bar the test must clear — set it BEFORE you look, no moving it after).
• Results — two columns: Invalidated / Validated.
• Across the top, Steve Blank roars: GET OUT OF THE BUILDING. You cannot fill this rock sitting in your cave!

And remember: a pivot is not a failure. A pivot is a structured response to invalidated learning.

Build-Measure-Learn — the fire-loop

Eric Ries gives the engine:

• Idea — your best guess right now.
• Build — make a MVP (Minimum Viable Product). Three parts: Minimum (smallest build that tests the Riskiest Assumption) + Viable (works enough for tribe to really use) + Product (a drawing on a rock, a fake storefront, a Wizard-of-Oz trick where a caveman hides behind the curtain doing the work by hand, or real software). Ugg warn: an MVP is the CHEAPEST test, NOT a half-broken final spear! It may look nothing like the finished spear — that is fine, it only tests the one guess.
• Measure — watch what tribe DO, not what they say.
• Learn — one of two shouts: Persevere (data good, refine and keep going) or Pivot (data bad — change ONE big guess: customer, problem, solution, channel, pricing, or market type — and run the loop again). Change only ONE thing, or you never know which change moved the tracks.

Scoreboard and game: Validation Board = scoreboard. BML loop = the game. Each loop scratches exactly one row on the board.

Find the hungry one — the Earlyvangelist Pyramid

Not all tribe are equal for your FIRST sale. The Earlyvangelist Pyramid — five layers, wide bottom, sharp top:

• (base) You know they have a problem (they may not know yet)
• They know they have a problem
• Actively looking for a solution
• Already hacked their own patched-together fix
• (apex) Have budget — berries set aside to solve THIS problem

An earlyvangelist sits at the apex — Steve Blank's word for early-adopter PLUS evangelist. They forgive your ugly MVP (pain is sharp!) and bring you new tribe for free (they truly cheer). So "who is your first customer?" is NOT "everyone with the problem" — it is the hungry one at the apex with budget. Sell there first; that is your wedge, then walk DOWN the pyramid to the bigger crowd later, after PMF.

Ugg remember

• Old Map = straight line (executes a plan). New Compass = loop (discovers a model). Search first (pivot allowed), Execute after; the gate is PMF. Grow big before PMF and the tribe burns all its shiny stones.
• Problem-Solution Fit (Discovery) comes BEFORE Product-Market Fit (Validation). Two rocks, in order — don't brag PMF holding only PSF.
• Detective Phase: hide your spear, ask the four "how do you do it NOW" questions, LISTEN. Never pitch — friends lie to be nice.
• MVP = Minimum + Viable + Product — cheapest test of your Riskiest Assumption, not a half-built final thing. Run the BML loop (Idea → Build → Measure → Learn → Persevere or Pivot), one guess per pivot; log each result on the Validation Board.
• Earlyvangelist apex = the one with budget — sell there first. Always: GET OUT OF THE BUILDING. No business plan survives first contact with customers.
