On 23 July 2026, HubSpot launched Agent Hub and Agent Builder in public beta for Professional and Enterprise customers. If you've been quietly running a Customer Agent here, a Prospecting Agent there, and wondering whether any of them know the others exist - that's precisely the gap this closes. Here's what actually shipped, what it means in practice, and what to do about it.
HubSpot has been shipping individual AI agents for a couple of years now - Customer Agent for support, Prospecting Agent for sales outreach, various others along the way. Each one is genuinely capable. The catch is that they've been operating in their own little worlds.
HubSpot's own example of the problem is a good one: a Prospecting Agent reaches out to a contact the same week a Customer Agent is handling an open complaint from that same account, and neither agent has the faintest idea the other is talking to that customer. One arm doesn't know what the other is doing, which is a personnel organisational failure for a set of tools that are supposed to be smarter than that.
Agent Hub is the fix. A single console where every agent running across your go-to-market shares the same customer context, instead of each one working from its own narrow slice of the picture.
Agent Hub is best understood as the new home base for AI agents in HubSpot, in fact, it's the evolution of what used to just be called "Breeze Agents," now given its own proper hub rather than being scattered across other product areas.
Inside it, you get one place to:
See what's running. Every agent active in your account - the pre-built ones from HubSpot, anything you've installed from the Marketplace, and anything custom you've built - organised by the outcome it's driving. HubSpot's own framing groups agents by goals like building demand, winning deals, delighting customers, and scaling growth, rather than by which hub they happen to live in.
Check performance. Instead of digging through separate reporting for each individual agent, Agent Hub gives you visibility into what's actually happening - what's being resolved, what's being escalated, what's working.
Turn things on. If HubSpot has agents available on your plan that you haven't activated, they're visible here rather than buried in a settings menu somewhere.
Reach the Marketplace without leaving. Pre-built agents you might want to install are accessible directly from Agent Hub, rather than being a separate shopping trip through HubSpot's broader app ecosystem.
The genuinely useful shift here isn't any single feature. It's that "which agents do we have, and are they doing anything sensible" finally has one honest answer instead of five scattered ones.
Agent Builder is the other half of this release, and it's the part with real hands-on substance. It's also had a rename: this is what used to be called Breeze Studio.
Agent Builder is where you build and improve your own custom agents and automations - on a single canvas, in plain language, with no coding required. You describe what you want the agent to do, and it builds itself from that description, working from data that's already sitting in your CRM: contacts, deals, conversations, call transcripts, whatever context is relevant.
A few things worth knowing about how it actually behaves:
Agents and automations sit on the same canvas. You're not switching between a workflow tool and a separate AI tool - triggers, actions, and agent hand-offs connect in one place. Work that used to take a dozen manual steps can genuinely become one connected build.
Triggers are flexible. An agent can kick off from a scheduled time, a contact property changing, a webhook, or a third-party integration - not just a form submission.
You control how much autonomy it gets. Agent Builder includes approval steps, so you can require a person to sign off on each action while you're building trust in what the agent does, then loosen the reins once you're comfortable it behaves the way you expect.
It reuses your existing playbooks, in the sense that agents are built on the context already in your CRM rather than starting from a blank slate every time - the same records, history, and data your team already relies on.
One useful distinction while we're here: HubSpot separates agents from assistants. Assistants (accessed through Breeze Assistant) answer questions and provide guidance quickly - think of them as the fast, conversational helper. Agents, built and customised in Agent Builder, actually complete structured tasks and take actions in your account, which is slower because it's doing more. Worth knowing which one you actually need for a given job.
Agent Builder isn't only for building agents from a blank canvas. HubSpot's Marketplace includes pre-built agents you can install directly, then customise inside Agent Builder to fit your own business rather than starting from nothing.
Worth knowing before you install one: HubSpot-built agents come with default inputs, instructions, and tools that can't be edited, deleted, or rearranged. You're customising around the edges of a pre-built agent, not gutting it and rebuilding it from the frame up. For a lot of common jobs, the kind of task plenty of businesses in your position also need - that's a genuinely sensible starting point. Install, adjust what's adjustable, and see how it performs before deciding whether you need something fully custom instead.
This matters for how you approach the whole thing. The instinct with any new AI capability is to imagine the most elaborate possible use case and try to build it immediately. A better first move is usually the boring one: check what's already built, install it, and see whether it does eighty percent of the job before you invest time building the remaining twenty percent from scratch.
Here's the bit that actually affects your budget, and it's more nuanced than "everything costs credits now."
Agent Hub and Agent Builder themselves are included for all Professional and Enterprise customers - no extra fee just to access the console or start building.
Automations and workflows built inside Agent Builder don't consume HubSpot Credits. If what you're building is fundamentally rule-based - trigger, action, done - that's included in your subscription the same way workflows always have been.
Custom agents consume HubSpot Credits when they complete an action you've configured. This is usage-based, not a flat fee - you're charged as the agent actually does the work, not just for having it switched on.
This tracks with the broader shift HubSpot made back in April 2026, when its two flagship agents - Customer Agent and Prospecting Agent - moved to outcome-based pricing: you pay per resolved conversation or per recommended lead, not per attempt. If you've seen older material quoting a flat monthly credit allowance for these agents, that's now out of date - the current model charges for completed outcomes, which is a genuinely fairer structure than paying regardless of whether the agent actually got anywhere.
The practical takeaway: the free part is the visibility and the building tools. The part that costs money is the actual work the agents do, which is the right place for the cost to sit.
If you're already running HubSpot agents, here's the useful next step: go and actually look at Agent Hub. Most businesses running Customer Agent or Prospecting Agent have never had a single view of what those agents are doing side by side, this is your first real chance to see the whole picture rather than piecing it together from separate reports.
If you've been meaning to build something custom but didn't have the technical resource to justify it, Agent Builder's natural-language, no-code approach genuinely changes that calculation. Describing a task in plain English and having it build the automation is a much lower bar than it used to be - worth revisiting anything you'd previously dismissed as "we'd need a developer for that."
And if you're running multiple agents that have never been coordinated - which, per HubSpot's own framing, is a genuinely common problem - this is the moment to check whether your Prospecting Agent and your Customer Agent are stepping on each other's toes with the same accounts. That coordination gap is exactly what this release exists to close, but only if someone actually goes and looks.
Because this is public beta, expect the usual early-stage caveats: features will likely shift, some rough edges are normal, and it's worth treating what you build now as an evolving thing rather than a permanent fixture.
Agent Hub and Agent Builder aren't a flashy new AI capability so much as HubSpot finally doing the organisational housekeeping its own agent sprawl needed. One place to see what's running, one canvas to build what's next, and a cost model that charges for completed work rather than mere existence.
If you're running HubSpot AI agents and you can't currently answer "what are they all doing and do they know about each other" - that's the gap this release was built for. Worth a look this week, not next quarter, while it's still fresh enough that most of your competitors haven't worked out what to do with it either.
