# Datadog — Capital Time Machine Explore 5 documented funding stages and their hypothetical value at the IPO offer price. Canonical citation: https://capitaltimemachine.com/private/datadog Dataset revision: ctm-research-2026-10-01; evidence register reviewed: 2026-09-19. Each observation retains its own check date. Publisher: CapitalTimeMachine. Methodology: https://capitaltimemachine.com/methodology ## What this supports Published four-decimal issuance prices already reflect the four-for-one and September 2019 three-for-one splits. The pro forma disclosure converts 179,011,431 preferred shares into the same number of Class B shares; Class B converts 1:1 to Class A equivalents. The table date is not a purchase date. The 2019 repurchase is not used as an entry price. No additional split or holder-specific conversion adjustment is applied. IPO offering-price mark only, not realized proceeds or proof of investment access. ## Limitations - Historical research and hypothetical arithmetic, not live quotes, investment advice or an offer to invest. - Company valuation changes are not shareholder returns. Financing, dilution, security rights and exit access matter. - IPO offer-price marks are not realized sale proceeds; minimum investments and access are not established. - User-entered prices and valuations are assumptions, not sourced observations. Fee and carry treatment is stated by each method; taxes and distributions are excluded. - Selected surviving companies are not representative of private-market outcomes; investments may lose all value. ## Sourced observations ### DDOG-SEED — Seed Value: 0.0575 USD; scope: per_share_issuance_price Date: 2019-06-30; precision: day; role: historical_table_snapshot; actual investment date: not established Security: Seed preferred; share basis: retrospectively_split_restated Verification: primary_verified; checked: 2026-09-17 Published four-decimal issuance prices already reflect the four-for-one and September 2019 three-for-one splits.
