Evidence strongly supports the core of Jason’s prediction— that Founder University, in partnership with Sanabil (not “Sonabel”), would run a program based in Riyadh starting in November 2025 — but there is no clear public evidence about him personally spending a full week there, so the prediction as normalized can’t be fully verified.

What’s confirmed

• Sanabil and Jason Calacanis’s firm LAUNCH announced “Sanabil Founder University by LAUNCH,” a 12‑week pre‑accelerator based in Riyadh for early‑stage founders. (zawya.com)
• Multiple independent outlets and the official press release state that the first cohort begins in November 2025 in Riyadh and that it is a Sanabil–LAUNCH/Founder University collaboration. (zawya.com)
• The official program site for Sanabil Founder University by LAUNCH lists “Cohort 1 – November 2025” and describes it as a 12‑week pre‑accelerator for MENA-based startups, with select in‑person sessions in Riyadh. (mena.launch.co)
• The published schedule shows in‑person “Day 1–3” programming in Riyadh from November 3–5, 2025, including talks and founder activities, with Jason Calacanis listed as a speaker on Day 1 (“Startups 101”) and Day 3 (founder pitches), indicating he is physically present on at least those days.

• In his own announcement, Calacanis wrote that “On November 3rd, I’ll be on the ground in Riyadh to launch Sanabil Founder University by LAUNCH,” and invites founders to spend 12 weeks in the Kingdom, reinforcing that the program is indeed centered in Riyadh during that period. (linkedin.com)

What remains uncertain

• The normalized prediction adds the specific detail that this would be a “week-long” program in Riyadh and that Jason (“B”) would be “physically spending a week there.”
• Public materials consistently describe the initiative as a 12‑week program with a mix of virtual and in‑person components, not as a strictly “week‑long” program. (mena.launch.co)
• While the schedule and Calacanis’s own announcement confirm he is in Riyadh to launch the program and present on at least November 3 and 5, no reliable source specifies that he stayed for a full continuous week, nor do they frame the entire program as only a week long.

Because the partnership, location, and November 2025 timing are clearly correct, but the exact duration of his stay (a full week on the ground) is not verifiable from public sources, the overall prediction — as normalized with the “week‑long / week there” detail — is best classified as ambiguous rather than fully right or wrong.
