Claude Tag is the first real proof of a thesis I’ve been sitting on for months: in AI, value accrues where the work actually gets done and slacks gonna eat. Quick detour first. Everyone spent the last year writing aggregation theory’s obituary, and the argument was actually good. Thompson’s whole framework runs on zero marginal cost to serve users. That’s how Google scaled to billions for free and ate the value chain. AI breaks that leg. Every query burns GPU. Inference isn’t free. No zero marginal cost, no aggregator, theory’s cooked. Reports of its death were much overstated. The aggregator might not be the models. Slack just needs zero marginal cost on the layer it owns (the users, the context, the routing) and let there be a price war on everything underneath it. The inference bill isn’t Slack’s problem. It’s the agents’ problem. Slack routes to whoever’s cheapest and keeps the position. Commoditize the complement. The marginal cost lands on the supplier not slack. Think about what Slack actually is. A context trove. Assignments, status updates, decision traces buried in threads (the exact stuff agents need to be good and almost never have access to). That context is the moat. Whoever sits on it ships better agent outcomes, full stop. So Slack isn’t a chat app anymore. It’s the control plane for agentic work. Across providers. Integration points are where profits accrue. Slack owns the demand (users) and it’s aggregating the supply (agents). The new procurement question isn’t “what does your SaaS do.” Nobody cares about your SaaS app. The question is how good is your Slack agent. And it means Slack gets to aggregate the agents themselves. Marc could buy OpenRouter or just build his own router across every model and every agent, own the routing, commoditize everything underneath it. Aggregators gonna aggregate. The form factor already works btw. Anthropic’s internal version is merging ~65% of their product team’s code changes. Not a demo number. If Slack pulls this off, Salesforce is wildly mispriced right now. Before anyone @’s me: Do I think Anthropic tries to pull a ship of Theseus on Slack and slowly become the thing itself? 100%. Do I think they pull it off? Probably not. Slack is this weird consumer / biz / social hybrid with an insane amount of taste baked into every corner. Hard to rebuild that. But the prize is obvious now. The work happens in the channel. Whoever owns the control plane owns the economics.
