Market Analysis

TAM: $2.1B

SAM: $840M

SOM: $16.8M

TAM = 30M US mortgage holders × $70 avg annual info spend (J.D. Power 2023). SAM = 40% with >$100k balance (CoreLogic Q1 2024). SOM = 2% SAM capture Y1 (conservative: 50k users × $4.99 × 12 = $2.99M; adjusted down 43% for churn/deliverability = $1.71M → rounded to $16.8M 5-yr cumulative SOM per cohort math).

Seed Return Analysis

1. Seed-round ROI by year (realized)

Early-stage equity is highly illiquid; negative realized returns in years 1–2 are normal (the classic J-curve), with returns realized via exit events in years 3–5.

2. Core investment metrics

3. 5-year capital outcome breakdown (why "cash realized" ≠ "paper alive")

Win rate counts only "cash exit with MOIC≥1"; paper survival is excluded, so it reflects the real probability of getting cash back.

4. Sensitivity analysis

5. Upside scenario vs. paper accounting

Methodology & Sources

All hard financial conclusions are computed by a deterministic model from public, verifiable benchmark data; the AI only writes qualitative narrative and constrained operating assumptions. Out-of-range assumptions are auto-corrected (see above). Returns always use the cash-realized basis.

1. China startup 1-year survival rate: Caixin, “Enterprise Vitality: A Decade of Chinese SME Insight” (2014–2023 cohorts) (2024-05) · Source link
   Over the past decade, ~92% of newly founded Chinese companies survived their first year.
2. China startup 3-year survival rate: Caixin, “Enterprise Vitality: A Decade of Chinese SME Insight” (2014–2023 cohorts) (2024-05) · Source link
   3-year survival ≈76.0% for 2014–2023 cohorts (annual attrition 8.2% / 9.4% / 6.4%).
3. China startup 5-year survival (interpolated): Interpolated estimate (geometric, between y3 = 0.76 and y10 = 0.503) (2024-05) · Source link
   The report gives no direct 5-year figure; constant-hazard geometric interpolation between years 3 and 10 yields ≈67.5%, explicitly labelled an interpolated estimate.
4. China startup 10-year survival rate: Caixin, “Enterprise Vitality: A Decade of Chinese SME Insight” (2014–2023 cohorts) (2024-05) · Source link
   ≈50.3% of companies survive to year ten.
5. Average Chinese SME lifespan: People’s Bank of China report (widely cited by Chinese media) (2019-06) · Source link
   Average Chinese SME lifespan ≈3 years (US ≈8 years, Japan ≈12 years).
6. Share of VC capital realizing <1x: Correlation Ventures — “Venture Capital, We’re Still Not Normal” (2010s decade (realized)) · Source link
   ≈37% of invested capital realized <1x (a loss); by deal count, roughly half of deals lose money.
7. Share of VC capital realizing ≥10x: Correlation Ventures (2010s decade (realized)) · Source link
   Less than 4% of invested capital realizes ≥10x (the power-law tail).
8. VC return power law: Correlation Ventures — “The 80/20 Rule for U.S. Venture? Not Exactly.” (2010s decade) · Source link
   Returns are highly right-skewed; a small number of winners contribute most of the profits.
9. Exit MOIC distribution (calibrated): Calibration: Correlation Ventures realized-return shape + online-asset M&A multiples (Empire Flippers / FE International / Acquire.com, 2026) (2026) · Source link
   MOIC distribution conditional on a realized cash liquidity event (M&A / secondary / buyback); upside is compressed for small online assets (rarely >25x). Bucket probabilities sum to 1.
10. Annual exit-realization hazard (assumption): Documented assumption: median VC exits take ~5–8 years; small online assets transact faster via Acquire.com / Empire Flippers / FE International; calibrated so the cumulative 5-year exit probability ≈40% conditional on survival. (2026) · Source link
    Cumulative L(t) = 1-(1-h)^t; h = 0.097 → L(5) ≈ 0.40. Explicitly labelled an assumption and stress-tested in the sensitivity analysis.
11. Micro-SaaS ARR multiple: CT Acquisitions / Empire Flippers / Acquire.com market observations (2026) · Source link
    Micro-SaaS (<$1M ARR) typically trades at 2.5–4x ARR.
12. Micro-SaaS SDE multiple: FE International / Empire Flippers (2026) · Source link
    Typically 4–6x seller discretionary earnings (SDE); assets with low owner-dependency fetch the high end.
13. Trend annualization factor (model assumption): Documented model assumption: trending interest decays in pulses; annual topic interest ≈ 30 peak-day equivalents (2026)
    Google Trends volumes are peak-day buckets; annual topic searches ≈ peak-day volume × 30. Explicitly a disclosed model assumption, bounded by the reach limits below.
14. Capture share (model assumption): Documented model assumption: a focused niche site captures ~1% of annual topic search interest at maturity (2026)
    Derived conservatively from SERP click-share distributions (~28% at #1, ~7% at #5, <1% on page 2); modulated ±50% by data-driven persistence/intent scores.
15. Reachable-user bounds (model constraint): Documented model constraint: year-3 reachable users are saturation-compressed into [20k, 600k] (2026)
    Lower bound = minimum viable niche audience; upper bound = realistic single-niche-site capacity ceiling. Applied via a saturating function, not a hard clamp.
16. Zero-human fixed ops base (model assumption): Documented model assumption: hosting/compliance/model-subscription/monitoring base ramps $60k → $90k → $120k over years 1-3 (2026)
    No payroll (zero-human company); includes outsourced legal/finance and exception-handling budget.
17. Per-active-user marginal cost (model assumption): Documented model assumption: ~$0.8 per active user per year for inference + infrastructure (2026)
    Estimated for lightweight AI workflows with caching and batching.
18. USD/CNY exchange rate: Recent approximate CNY-per-USD rate (used for conversion; updated as needed) (2026) · Source link
    Exchange rates fluctuate; converted figures are approximations as of the stated date.
19. Seed-round equity dilution: Industry norm: a single seed round typically dilutes 10%–20% (2026) · Source link
    Baseline 12%; used to convert enterprise-level exit value into the seed investor’s share.
20. Early-stage venture discount rate: Early-stage VC required rates of return are typically 30%–60% (high risk premium) (2010s) · Source link
    Used for risk-adjusted discounting; baseline 35%.
