# Market Position & Share Analysis

## What this is

A method for answering "where do we actually stand" with rigor instead of a pitch-deck TAM. In the market-intelligence tradition, it defines the market precisely (not the biggest number you can justify), sizes it top-down and bottom-up and reconciles the two, estimates share and — more importantly — share *trajectory*, positions the company against real competitors on the dimensions customers buy on, and reads market acceptance signals (adoption, retention, willingness to pay). Every figure is tied to a source and labelled measured or estimated, so the picture survives a skeptical investor.

## What this is NOT

Not affiliated with or endorsed by S&P Global or any market-intelligence firm — it uses the publicly understood discipline (defined markets, triangulated sizing, competitive positioning) as a reference lens, not their data products or brand. Not a TAM-inflation exercise: the fastest way to lose credibility is a market definition drawn to hit a big number, and this refuses it. Not investment advice, and not a substitute for primary market research. Estimates are labelled estimates; a sourced range beats a confident single number.

## Method

1. **Define the market precisely.** The specific segment you actually serve and compete in — not the adjacent universe. A precise smaller market is more useful than an inflated large one.
2. **Size it two ways and reconcile.** Top-down (industry data) and bottom-up (units × price, or customers × ACV); when they disagree, find out why — the reconciliation is where the honest number is.
3. **Estimate share and, above all, trajectory.** Current share matters less than whether it's rising or falling and how fast; a small rising share beats a large eroding one. Label the estimate.
4. **Position against real competitors.** Map the field on the dimensions customers actually decide on (not the ones flattering to you); name where you genuinely lead, match, and lag.
5. **Read market acceptance.** Adoption rate, retention/repeat behaviour, willingness to pay, and reference-customer strength — the demand-side evidence that the position is real, not asserted.
6. **Identify the structural forces.** Switching costs, network effects, distribution, regulation — what actually protects or threatens the position over time, beyond the current feature race.
7. **Triangulate and cite.** Cross-check figures across sources; attach each number to where it came from; flag the ones that are single-sourced or weak.
8. **State the position honestly.** A clear read of where the company stands and where it's heading, with the confidence level and the data gaps named — not a number designed to impress.

## Quality bar

The market is defined precisely to what's actually served · size is triangulated top-down and bottom-up and reconciled · share and its trajectory are estimated and labelled, with trajectory emphasised · competitors are mapped on the dimensions customers buy on, with honest lead/match/lag · market acceptance (adoption, retention, WTP) is read from evidence · structural moats and threats are named · figures are triangulated, cited, and weak sources flagged · the position is stated with confidence levels and data gaps.

## Guardrails & escalation

An analytical method in the market-intelligence tradition — not affiliated with S&P Global or any firm. Market definitions are honest, not drawn to inflate TAM. Every figure is sourced and labelled measured or estimated; single-sourced numbers are flagged. This is not investment advice or a substitute for commissioned primary research — a raise or an investment decision routes to qualified advisors, and where the stakes justify it, to primary market research. A number without a source is not used here.
