Company Funding: Validation Set

75 companies for developing and tuning against the company funding benchmark. Every provider receives the same company domain, and the benchmark scores the latest funding round it returns.

Dataset Description

75 examples: 67 rounds announced between 2026-09-14 and 2026-10-14, and 8 older rounds from earlier in 2026. None of them appear in the public release used by the leaderboard. Each row has:

• case_id: stable identifier, prefixed val-.
• slice: recent for rounds announced inside the 2026-09-14 to 2026-10-14 window, older for anything earlier.
• input_domain: the domain sent to every provider.
• input_name: the company name, for reference.
• latest_stage: the most recent funding round, in the benchmark's canonical stage taxonomy (pre_seed, seed, series_a through series_h, private_equity, venture_unspecified, debt_or_credit, and others).
• latest_announced_on: the date the round was announced, YYYY-MM-DD.
• latest_amount: the round size in currency. Empty when the amount was not disclosed.
• currency: ISO currency code for latest_amount.

Every reference value was reviewed by hand.

Scoring

The headline metric is correct stage yield: the share of companies for which a provider returned the correct latest stage. A missing or wrong stage lowers the score. An LLM judge compares each provider's stage, date, and amount with the reference values, using these rules:

• Series A through H need the same letter. Same-letter suffixes such as B1, B2, or B+ match Series B.
• Seed, Seed Bridge, and Pre-Series A are equivalent. Seed and Pre-Seed are different stages.
• Private equity, growth equity, and strategic or corporate investment are equivalent.
• For other disagreements outside the Series letters, an exactly matching date or amount can make the answer correct.

Date and amount count toward returned-data coverage, but they don't affect the headline score.

Scores on this set are directional only and are not comparable to the leaderboard.
