Confidence breakdown

How much we trust each of the four valuation methods for this specific company, and why.

Method A — Peer-multiple

weight 25%→ $0.4B23% confidence

↳ Effectively excluded from the blend — this method is structurally unreliable for this company.

Growth-weighted peer EV/Revenue: 20.1x → 25% private-company discount → 15.1x on $25M revenue. Output implies less than half the recent market anchor ($2B) — this company is likely valued on optionality / non-revenue factors and Method A is structurally less reliable here.

Method B — Secondary-implied

weight 45%→ $1.5B55% confidence

Recency-weighted average of 2 secondary indications (180-day decay)

Method C — Primary time-decay

weight 20%→ $2.0B20% confidence

↳ Effectively excluded from the blend — this method is structurally unreliable for this company.

$1.7B round (2023-02-24) × 6.76× growth × 0.85× multiple decay over 3.3 years — capped at 1.3× recent secondary ($1.6B → $2.0B)

Method D — Sector momentum

weight 10%→ $1.8B11% confidence

↳ Effectively excluded from the blend — this method is structurally unreliable for this company.

$1.7B × (1 + 1% p.j.)^3.3yr = $1.8B via WCLD ETF-proxy

Overall confidence

36%

Weighted average of the four methods. Above 65% is high, 40–65% medium, below 40% low.

Profile: a hypothetical employee who joined Temporal 24 months ago (2024-05-26) with 2,000 options, on the standard 4-year vesting schedule with a 1-year cliff.

Transparent assumptions

What we assumed where exact data isn't available. If any of these don't match your situation, the numbers above will be off.

Fully-diluted share count

160M shares

We don't have authoritative cap-table access for private companies. The number above is reconstructed from SEC Form D filings, secondary-market price-vs-valuation math, and leaked share-class summaries. Actual fully-diluted count (including unvested option pool and SAFEs) may differ by 5–15%.

Common-stock waterfall

1.0× to common

We assume a clean common-stock outcome — i.e. preferred-share liquidation preferences and ratchets do not extract value before common. In a down-exit, this assumption can be very wrong: preferred stack can take 30–70% of proceeds.

Private-company illiquidity discount

25% off public peers

Applied to Method A (peer-multiple). Per-company because category leaders with deep secondary markets and a clear IPO path warrant a smaller discount than early-stage names. The literature range is 10–35%; for Temporal we use 25% based on secondary-market depth, valuation history, and proximity to liquidity.

Revenue growth assumption (Method C)

80% YoY

Compounded forward from the last primary date to today to estimate the company's value drift. Set per-company based on disclosed or reported ARR trajectory. Method C is further capped at 1.3× the most recent secondary trade (if any) to stop runaway extrapolation when revenue growth outpaces what the market is actually paying.

Sector ETF momentum (Method D)

WCLD @ 1%/year

Method D applies the trailing return of WCLD as a market-proxy adjustment to the primary valuation. Crude — meant as a tiebreaker when peer and secondary data conflict, not as a primary signal.

Outlier auto-downweight

Methods >50% from median get ½ weight

Robust-statistics safety net: any method whose output strays more than 50% from the median of the other three methods has its confidence weight halved when computing the blended mid-point. Prevents a single bad extrapolation from dragging the headline.

Recency decay for secondary trades

180-day half-life (e⁻ᵈ/¹⁸⁰)

A trade from 30 days ago counts ~5× more than one from 180 days ago. Tunable; some platforms use shorter half-lives.

Tax estimate

US federal only, single filer

Uses 2024 US federal brackets, ignoring state tax, NIIT, AMT credit recovery, and any other deductions. Treat as a directional sanity check, not a tax bill.
