What the first 2,400 thinkers say

★★★★★
I replaced 30 minutes of Instagram with 3 minutes on Cortx. My CDS hit 6,200 in 3 weeks and my manager noticed a genuine shift in how I frame problems.

The Strategic Scenarios are insane. I solved a "budget freeze" at 7am and by 3pm a real version came up in a client call. I already had the framework ready.
