Marc Andreessen and Ben Horowitz will host their Clubhouse show "One On One with A & Z" on Wednesday, September 22, 2021 at 5:00 PM Pacific.
Unresolvable The public record could not settle it.
Said for an organisation they lead or work for; it counts on both records.
What would count as true or false
The claim is that Andreessen and Horowitz would host their Clubhouse show 'One On One with A & Z' on Wednesday, September 22, 2021 at 5:00 PM Pacific. TRUE: the episode, hosted by both of them, took place on Clubhouse at or about that date and time. MOSTLY TRUE: it took place on September 22 with both hosts, but the start time shifted somewhat, or one minor detail differed. MOSTLY FALSE: it was postponed to a later date, or took place without one of the two named hosts. FALSE: a cancellation notice, a statement that it did not happen, or the absence of an episode in a dated episode list for that period shows it was not held.

Reasoning
E1 and E2 confirm that "One on One with A and Z" was an a16z Clubhouse show hosted by Marc Andreessen and Ben Horowitz, but they give no date for any session. E3 and E4 list podcast excerpts published on Aug 25, 2021 (#10) and Sep 28, 2021 (#11). These are publication dates for podcast excerpts, not the dates the live Clubhouse sessions were held. Episode #11 appearing on Sep 28 fits with a session on Sep 22, but it does not show that the show took place on Sep 22 at 5:00 PM Pacific with both hosts, so the evidence settles neither outcome.
