Hosted a happy hour last night with founding AEs and early GTM operators in SF during RSA week. Last night was about more than one conversation. We are building a community of sellers who want to stay sharp, share what’s working, and be connected to what’s coming next. That includes being in the loop when Greylock is making new investments. If we’re backing a company, I want the best sellers to know about it early. If you’re building or selling at the early stages and want to be part of this — reach out. #RSAC2026 #Startups #GoToMarket #Greylock #FoundingAEs #FoundingSEs

Great read from Nir Zuk, the founder and CEO of Cylake, on why sovereignty is becoming the defining boundary in cybersecurity. In the AI era, the most important security boundary will no longer be the network. It will be who controls the infrastructure that processes the data. 📖👇
