Methodology
Entrepreneurial Check publishes the citable table of its modeled founder equity estimates at https://entrepreneurialcheck.com/dataset.
Entrepreneurial Check publishes model-based estimates from public Y Combinator directory data and market assumptions — illustrative only, not appraisals or verified net worth.
Company valuation
- Every private company with a published raise: company mid = raise × 10. Seed and Series A use the same multiple.
- YC-only with no published outside raise: default mid $7M.
- Disclosed or tracker valuations override raise × 10 when we have them.
Ownership
Two-founder teams with a CEO plus a COO, CTO, or other partner always split the remaining founder pool 60/40.
On seed / YC-only, that pool is 100% (SAFE investors are not treated as priced equity yet), so a seed CEO is 60% of the company mid and the partner is 40%. After a priced round (Series A+), investors have converted and the remaining founder pool is smaller (about 28% at A, 17% at B, 10.5% at C+), then split 60/40. Series A is about 16.8% for the CEO and 11.2% for the partner. These are assumptions, not disclosed cap tables.
Paper wealth
Mid ≈ company valuation × modeled ownership. Ranges use a 0.7×–1.5× valuation band.
Public figures beyond YC
For well-known public-company founders and operators, the mid can be a published tracker estimate (Forbes Real-Time or Bloomberg Billionaires) with a citation and as-of date, not the seed-stage raise model. Ownership uses disclosed proxy / 13D figures when we have them.
Those marks move daily. Treat them as dated snapshots, not appraisals.
Sourced rows are collected on startup founder equity estimates. The same rows download as dataset.csv. Figures there are model estimates, not verified net worth.
