  • Perplexity3.7
    DirectLLM chatbot

    Brad Gerstner has an angel check in Perplexity and has publicly championed the product as the answer engine that's rewriting commercial search. In a LinkedIn post he framed Perplexity's differentiation as 'connecting people to relevant content/information in a more effective way' versus ChatGPT's tendency to make underlying content irrelevant. He repeats the thesis on BG2 episodes where he positions Perplexity as the meaningful challenger to Google's search incumbency.
