“Lifetime access” to anything on the internet is never a wise offer and sets one up for potential issues down the road. You would think he’d know to word that differently. Could’ve achieved the same outcome with some sort of 10-year license or the like.

Vanta is a rocketship and we're proud to be early backers 🚀🚀 Right on the heels of their $150M Series D, we had their CRO, Stevie Case, on the podcast. When Stevie became CRO at @vanta, the company had massive inbound, one-call closes, and a market lead. They also had no CRM…

I suspect the next few weeks after Grok 4 follows the same pattern as Grok 3 xAI beats everyone to market with the first RonnaFLOP model. The benchmarks show the 10-20% improvement the scaling law suggests. In the coming months, the other labs release their RonnaFLOPs, catch up.
Fierce competition in this space just continues to push everyone to go bigger and go faster. Massive win for the rest of us.
