Glean has grown into a $7.2B company by giving employees AI assistants and agents that extend their capabilities.CEO Arvind Jain is back on Grit alongside Joubin Mirzadegan. Here’s what stood out:“My mindset by default is that if you build something last year, that it's got to be obsolete. There has to be a new way to do that thing better today. If not, then it's just lack of imagination.”“I have no doubts that AI capabilities are just going to increase more and more over the next few years.

I would say that we've not even used 1% of current capabilities of these models”“If you're trying to be everything to everyone, then you just cannot compete with somebody who's focused on a smaller problem and going deep into that.”You can also listen to Arvind’s earlier episode here: https://www.youtube.com/watch?v=iIH0Qp6d6bg&list=PLRiWZFltuYPF8A6UGm74K2q29UwU-Kk9k&index=96Guest: Arvind Jain, founder and CEO, Glean​Connect with Arvind JainX: https://x.com/jainarvindLinkedIn: https://www.linkedin.com/in/jain-arvind/Connect with JoubinX: https://x.com/JoubinmirLinkedIn: https://www.linkedin.com/in/joubin-mirzadegan-66186854/Email: [email protected] on LinkedIn:https://www.linkedin.com/company/kpgritFollow on X:https://x.com/KPGrit​Learn more about Kleiner Perkins:https://www.kleinerperkins.com/
