Factual Their own work or organisation

Sam Altman invested in TrialSpark, announced on 2021-09-30.

Resolved true The record shows it happened or was so.

Factual: Statements about the present or the past, checked against the record: did they hold up?

What would count as true or false

True: a dated record shows that Altman personally invested in TrialSpark and announced it on or around 2021-09-30, for example a tweet from him on that date, or a TrialSpark funding announcement listing him as an investor. Mostly true: he invested, but the announcement date is off by a few days, or the investment was made through a vehicle he controls. Mixed: the evidence shows only a related tie, such as investment through a fund he does not control, or an advisory role. Mostly false: there is only an expressed intent to invest, with no completed investment. False: records show he was not an investor in TrialSpark.

Reasoning

TrialSpark's press release dated 2021-09-30 [E1] says it raised a $156MM Series C round led by Sam Altman and Lachy Groom. Fenwick's deal note from the same date [E2] says the same, and the VC News Daily funding database [E3] lists Sam Altman among the investors in the Series C dated 09/30/21. Together these meet the true criterion: a dated funding announcement names Altman personally as an investor on that date.
