Since our 1999 investment in Google, Kleiner Perkins has long partnered with teams building the web’s core infrastructure. Today, we are co-leading Parallel’s $100M Series A with Index Ventures. Founded by Parag Agrawal, Parallel Web Systems is building the web for agents. The platform provides a native search API and index that can retrieve, organize, and rank tokens—not blue links—so AI systems can access and reason over accurate, current context. As part of the round, Mamoon Hamid will join Parallel’s board. As Parag Agrawal puts it: “Agents aren’t issuing keywords. They declare intent and receive high-signal tokens.” Watch Mamoon’s conversation with Parag ⬇️

“AI is the super cycle of all super cycles.” At this year’s Startup Grind, Aaron Levie and Mamoon Hamid reflected on two decades of building and investing at the frontier of enterprise software—and where we go from here. The conversation covered everything from the rise of product-led growth to the emergence of AI-native business models. A few highlights: 1. PLG still scales. Products like Box, Slack, and Figma didn’t just ride trends—they reshaped how software gets adopted. “All of these products had a magical out-of-box experience,” Mamoon said. “If something works at 10 users, it often works at 10 million.” 2. The best companies don’t just compete—they create. Mamoon put it simply: “When you create a category, you’ve created your own playing field—and you get to play your own game.” 3. AI is more than a feature—it’s a new foundation. Box is embedding AI across its platform to power knowledge work at scale. As Aaron explained, “We’re reinventing the company—while retaining all the current revenue.” The Startup Grind community is special, and we enjoyed being part of it.
