We're bringing back one of our most loved episode on Founders in Arms.

Parag Agrawal is the co-founder and CEO of Parallel, building infrastructure for the agentic web. Previously CEO of Twitter, Parag now leads a company architecting how AI agents will interact with the open web at orders of magnitude beyond current human scale. Two years after founding in stealth mode, Parallel recently announced a $100M Series B co-led by Kleiner Perkins and Index Ventures.

What you'll learn:

1. Why everything built for human web consumption will become irrelevant when agents become the primary users
2. How Parallel's APIs enable agents to search, fetch, and monitor the web with unprecedented scale and speed
3. The evolution from simple tool calls to autonomous sub-agents with real decision-making capability
4. Why the web must transition from "pull" (searching on demand) to "push" (alerting when conditions are met)
5. The new business models needed to compensate content creators in an agent-driven web
6. Parag's counterintuitive approach to fundraising: why VC rejections don't sting but customer rejections do
7. The rational game VCs play that founders misinterpret as genuine enthusiasm
8. Why Parag believes we're not in an AI bubble—but an overreaction is coming (and it'll be faster than dot-com)
9. How Parallel built quietly for a year before product-market fit arrived with the agent explosion
10. The operational philosophy of extreme in-person collaboration that shaped Parallel's early culture
