Scale's Meta transaction provided shareholder and vested-holder liquidity; its approximately $14.3B total is not a disclosed primary-proceeds figure. The issuer's $1B 2024 Series F mixed primary and secondary financing also lacks a split. An unrelated South African payments company named Scale raised $700K in 2024; that row was removed. The investor's contemporaneous Series A announcement establishes public disclosure by May 22, 2017, not settlement; one Series A database claim and two possible overlapping seed claims remain unresolved. YC's own profile (https://www.ycombinator.com/companies/scale-ai) confirms Summer 2016 participation but does not establish actual check amounts, security terms or two separate investments. This is not an independently reviewed complete history or a verified lifetime primary-funding total.

The founder's December 1 announcement gives raised capital, a lower-bound post-money valuation and Tiger Global as lead; other imported participants are not established by this source. The date is the announcement date, not authenticated settlement. Public investor names do not establish subscribing legal vehicles, allocations or retained current ownership.

Series A

Accel (lead) · Y Combinator (lead)

The issuer discloses $4.5M led by Accel. Daniel Levine's contemporaneous May 22, 2017 announcement (https://medium.com/accel-insights/scale-ceb24ddc9c5b), linked by Accel's August 2018 account, establishes disclosure by that day. The issuer post displays July 16, 2017; both link the same WSJ report (https://www.wsj.com/articles/scale-helps-engineers-outsource-microtasks-1495452603), not two separate Series A rounds. The observation uses the investor announcement date, not an authenticated closing date. The issuer's separately cited August 2018 retrospective specifically names Accel and Y Combinator as A leads, rather than deriving YC participation from accelerator terms. Its pooled individual names are not all assigned to A; board appointment is not personal subscription. The May 24 database claim may overlap.

Seed

Investor participation not independently verified

FundBat lists a $120K August 1 seed with a Y Combinator lead label, without a transaction-specific source link. Possible overlap with the June seed database claim; exact settlement, amount, security type and subscribing vehicle remain unverified. Retained as an unresolved database lead, not a second authenticated YC check or exact primary proceeds.

Seed

Investor participation not independently verified

The Seedlist profile explicitly says AI-generated and bases its approximate seed amount on standard YC program terms, not a Scale-specific closing record. Possible overlap with FundBat's August seed claim. Program participation alone does not authenticate Scale's actual check, security terms, subscribers or settlement; amount and financing kind remain unresolved.
