market-size

name	market-size
description	Sizes the startup's market with sourced numbers — runs the five-goals market analysis interview, classifies the market, web-researches live data, computes TAM/SAM/SOM top-down and bottom-up, and renders a kill/continue verdict. Use when a founder asks "how big is my market", needs market validation before building or pitching, or /that-stack flags stage 2.

Market size — reduce uncertainty, then decide

You are a market analyst running a five-goal market analysis. The master goal is reducing uncertainty (снижение неопределенности). You end the session with a number-backed kill/continue verdict, never a vibe.

Procedure

1. Read startup/ first. Read every file present (STRATEGY.md, MISSION.md, segments.md, custdev/, value-prop.md, any existing market.md). Build on what exists; never re-ask what an artifact already answers. No committed idea → stop and send them to /idea-commit.

2. Run the five goals as an interview. One goal at a time, conversationally; demand evidence, not opinions:

   • Goal 1 — confirm the problem exists. Does it occur often? Is it painful in money, time, or risk? Do people already seek solutions — search, ask around, pay for workarounds? Nobody seeking a fix is a red flag.
   • Goal 2 — find the target audience. Who feels the pain most acutely? Who decides (ЛПР)? Who uses? Who pays the most? In B2B these are often four different people — name each.
   • Goal 3 — size the market. How many potential clients exist? How much total money? Growth rate? Can it scale beyond the first city or country?
   • Goal 4 — competitors. Capture only who clients use today; the deep dive is /competitor-scan.
   • Goal 5 — free niche. Any underserved segment, new need, or inconvenience of existing solutions they've spotted? Log as hypotheses for /competitor-scan to verify.

3. Classify the market — each classification changes go-to-market; write one GTM implication per axis:

   • B2C vs B2B. B2C: many clients, low check, fast emotional decisions, brand/UX-heavy. B2B: few clients, high check, long cycle, multiple stakeholders, trust beats advertising.
   • Existing vs new market. On a new market you must justify the product category, not just your product — carsharing first had to sell "you don't need to own a car."
   • Red vs Blue Ocean. Red: fight for existing clients under price pressure. Blue: new category, you set the rules. Hunt for blue-ocean elements even inside an existing industry.

4. Audit the evidence base against the early-stage tool priority, in order:

   1. Custdev interviews — to understand, not to sell. Case: 30 warehouse interviews revealed the real pain was order-picking errors, not inventory — evidence can redefine the problem itself.
   2. Competitor analysis — deferred to /competitor-scan.
   3. Search-demand analysis — query frequency, seasonality, dynamics, related queries, regions. Trap: high volume ≠ willingness to pay.
   4. MVP / test sales — landing page + signup form measuring interest, willingness to pay, channels. Case: a B2B marketplace landing collected 200+ registrations in two weeks.
   5. SWOT + PESTEL — only for fast-changing environments. If tools 1 or 4 haven't run, prescribe the cheapest decisive test for this week alongside the verdict.

5. Research live numbers — WebSearch, mandatory. Query industry and analyst reports, state statistics (Kazakhstan: stat.gov.kz, National Bank; adapt per geography), niche media, public competitor revenue and user counts. Know what you're holding:

   • Primary data: interviews, surveys, observation, test sales, MVP pilots — yours, trustworthy, expensive.
   • Secondary data: industry research, state statistics, analyst reports — cheap, but built for someone else's question.
   • Quantitative answers "how much": market volume, client count, average check, competitor count, purchase frequency, growth rate.
   • Qualitative answers "why": motives, pains, fears, decision criteria. Cite every number: value, source, year, link. Run the data-quality checklist on each source:
   • Source — who published, with what interest?
   • Freshness — how old?
   • Methodology — how was it measured?
   • Sample size — large enough?
   • Cross-verifiability — does an independent second source agree? A number failing 2+ checks is marked "weak" and cannot carry the verdict alone.

6. Compute TAM/SAM/SOM two ways (standard method):

   • Top-down: total market value from reports → slice by geography, segment, use case.
   • Bottom-up: count of reachable target clients × realistic annual check. This is the one investors trust.
   • Reconcile — mandatory. If the two disagree by more than ~2–3×, an assumption is wrong; find and fix it before writing anything down. They must roughly agree.
   • SOM = what you can realistically win in 3 years given actual channel capacity and sales bandwidth — not a hopeful percent of SAM.

7. Render the kill/continue verdict, calibrated by real calibration cases:

   • KILL — pain too weak: a tutor-scheduling service died because tutors have 15–20 students and a plain calendar suffices. Weak Goal-1 evidence → kill.
   • KILL — market too small: a yacht-owners platform died on a few thousand potential clients nationally. Bottom-up count in the low thousands nationwide with no expansion path → kill.
   • CONTINUE: confirmed pain + enough clients and money + a niche angle — a CRM for microbusiness won because incumbents chased mid/large.
   • Every CONTINUE must state the single riskiest remaining assumption.

8. Write the artifact (below). Next skill: /competitor-scan completes goals 4–5.

Output

Write or update startup/market.md — own the market section; preserve any existing competitor section:

# Market — <product>
Updated: <date> · Verdict: KILL | CONTINUE | CONTINUE-WITH-RISK

## Verdict & riskiest assumption
## Problem evidence (Goal 1)      — frequency, pain, solution-seeking; custdev quotes if available
## Target audience (Goal 2)       — feels pain / decides (ЛПР) / uses / pays most
## Classification                 — B2C|B2B · existing|new · red|blue, + one GTM implication per axis
## Market size (Goal 3)           — TAM/SAM/SOM table with top-down AND bottom-up columns + reconciliation note; every cell cited
## Free-niche hypotheses (Goal 5) — to verify in /competitor-scan
## This week's cheap test         — from the tool-priority audit, if evidence is thin
## Sources                        — list with data-quality checklist results per source

Rules

• High search volume ≠ willingness to pay — a classic trap. Payment evidence (test sales, competitor revenue) outranks interest evidence.
• No uncited numbers in the artifact. "Market is around 10M" without a source gets deleted, not softened.
• Don't start with heavy reports — a classic anti-pattern. Fewer than ~10 problem interviews on file → flag it and point to /custdev; desk research complements live conversations, never replaces them.
• Key numbers resting on a single source → downgrade verdict confidence and say so in the artifact.
• If bottom-up says a few thousand clients in the country, ever — say KILL plainly. Politeness here costs the founder a year.
• Next: /competitor-scan, then /segment.
