Method and coverage
How this page is built
Two sources, joined on website domain. Where the join fails, the company still appears — with no figure rather than a guessed one.
Batch membership comes from Y Combinator's own company directory at ycombinator.com/companies, filtered to batch:Winter 2021. YC is the only authoritative record of who was in a batch, so nothing is added to or removed from that list here. The snapshot was taken on 15 August 2026.
Dealroom has no batch field, so each YC company is joined to a Dealroom company record by website domain. Where the domains do not meet, an exact name plus the same country is accepted, and only when exactly one Dealroom company matches both. 302 companies matched on domain and 23 on name and country. 11 did not match and appear in the table with no funding figure.
A company being backed by Y Combinator is not used as evidence of batch membership. Dealroom records Y Combinator as an investor in companies from every batch and in companies whose batch it does not know, so it can neither confirm nor rule out W21 membership.
Every figure on this page names the population it is computed over. Money raised is total funding on Dealroom's record for the 321 companies that have any, so it is a floor for the batch, not a total for it — the 15 companies without a figure include both unmatched companies and matched companies with no round on record. Sector, country and status come from YC and cover all 336 companies. Unicorn and exit counts are Dealroom flags and are counted over the 325 matched companies only.
Dealroom data pulled 15 August 2026. Rebuild both halves with node scripts/build-yc-batches.mjs --refresh.
