Pagers in an iPhone World: A CTO's Take on the Agentic Web

Parag Agrawal just said what every CTO is thinking

Twitter's former CEO sat down with Madrona Ventures last week and said something that should make every B2B infrastructure team stop what they're doing: "When the customer changes, everything changes."

The customer he's talking about? AI agents. Not humans. Agents.

In a conversation with Nikita Shamgunov (who led Neon through its AI pivot before the Databricks acquisition), Agrawal laid out the case that the entire web needs to be rebuilt. Not tweaked. Not optimized. Rebuilt. Because the thing consuming it is no longer a human with a browser. It's an agent with a task.

As a CTO, I've been thinking about this exact inflection point. Here's what hit hardest from that interview, and why it validates the direction we've been building toward.

The web was built for eyeballs. Agents don't have eyes.

Agrawal rebuilt search indexes from scratch at Parallel Web Systems because existing ones were designed for humans. Models have parametric memory. They don't browse. They don't scroll. They query. The ranking functions, crawl strategies, indexing priorities: all of it needs to change.

Shamgunov saw this firsthand at Neon. Agents were creating databases at 4X the rate of humans. Not slightly faster. Four times. That's not a usage bump. That's a different species of customer.

This is exactly the problem we tackled with the Agentic Web specification. The web isn't broken for humans. It's broken for agents. And agents are increasingly the ones doing the buying research, the vendor comparisons, the qualification conversations that determine where pipeline actually goes.

MCP isn't optional anymore

Shamgunov made a point that resonated with every infrastructure decision we've made this year: when Anthropic shipped MCP in December, his team launched MCP servers immediately. Not after a "strategy review." Not after a pilot. Immediately. Because in this environment, you ship when the standard ships or you miss the window.

We made the same bet. The Agentic Web spec is built on MCP, extended with A2A (Google's agent-to-agent protocol), NLWeb (Microsoft's natural language layer), and Schema.org. A /.well-known/mcp endpoint that any agent can discover. Open protocols, not proprietary lock-in.

When Agrawal says companies need to redesign for this new customer, this is what redesigning looks like. Not a chatbot on your homepage. A machine-readable endpoint that gives agents verified, real-time, first-party answers.

From pull to trigger: the shift that changes everything

Both founders agreed on where this is heading: the web shifts from pull-based (humans requesting information) to trigger-based (agents responding to world changes automatically). A single human action spawns massive agent work. CRM updates, competitive analysis, procurement workflows: things that take hours of human effort, completed in seconds.

For B2B, this means the buying conversation is about to get a lot faster and a lot more structured. An agent evaluating your product won't browse your features page. It will query your endpoint, get verified pricing, check compliance certs, and book a demo with the right AE. All in one interaction. All without a human touching a form.

The companies that expose structured endpoints win that interaction. The companies that don't? They're invisible to the agent. And increasingly, invisible to the buyer.

The pager line

Agrawal's sharpest quote from the interview: "Companies that don't redesign products for this new customer will be left selling pagers in an iPhone world."

That's not hype. That's an architectural truth. The web is being rebuilt around agent-to-agent communication. The protocols exist (MCP, A2A, NLWeb). The demand is real (agents are already mediating B2B buying). The infrastructure gap is closing fast.

As a CTO, the question I keep asking myself isn't whether to build for the agentic web. It's whether we're building fast enough. Because the window between "early mover" and "playing catch-up" in infrastructure shifts like this is measured in months, not years.

The interview is worth watching in full. Two founders who've operated at massive scale, both independently concluding that the web's primary customer is changing. And that everything downstream changes with it.

We built the Agentic Web because this infrastructure didn't exist. Watching two of tech's sharpest operators arrive at the same conclusion from completely different directions is the strongest signal I've seen that this shift is real, it's now, and the companies that move first will own the agent-to-agent layer that increasingly decides where revenue flows.
