What This Update Actually Is
HubSpot shipped Custom Signals inside the Buyer Intent app on June 30, 2026. Before this, buyer intent in HubSpot meant choosing from a fixed list of pre-built signal categories. Things like "visited your pricing page" or "viewed a competitor." Useful, but generic.
Custom Signals changes that. You write a plain-language description of a buying moment that matters to your specific business. HubSpot's AI reads it, monitors the web and available data sources, and surfaces companies that match. Every match comes with cited sources so you can verify the signal before acting on it.
The signals you define aren't siloed inside the intent app. They're first-class objects you can drop into any segment, workflow, lead scoring rule, or report. That's the part that makes this different from a bolt-on intent tool.
Why HubSpot Shipped This
Most intent data platforms assume every business cares about the same signals. They don't. A cybersecurity firm needs to know when a company posts a CISO job listing. A staffing agency needs to know when a manufacturing plant announces a new facility. A niche SaaS needs to know when a prospect files an RFP with language that matches their exact use case.
The internal frustration is real. Humans running revenue teams told us they were stitching together LinkedIn alerts, Google News subscriptions, third-party tools, and manual rep research just to find the right moment to call. That's expensive, inconsistent, and impossible to scale.
HubSpot is betting that CRM-native agentic intent (the AI actively monitoring on your behalf) is the thing that finally closes this gap. Custom Signals is a direct answer to the argument that generic intent platforms understand your ICP better than your own CRM does.
How to Use It Step by Step
- Open the Buyer Intent app in your HubSpot portal and navigate to the Signals tab.
- Click "My Signals" to see your existing signals and the option to create a custom one.
- Review the AI-generated signal suggestions. HubSpot reads your company profile and ICP to recommend starting points. Use them or ignore them.
- Write your signal in plain language. Describe the buying moment in one or two sentences. No prompt engineering. No boolean logic. Just say what you're looking for.
- Run the preview. HubSpot auto-generates a set of matched companies so you can see if the signal is too broad or too narrow before you turn it on.
- Check the source references on any matched company. Every detection includes citations so reps can verify before reaching out.
- Activate the signal. Once it's live, add it to a contact or company segment, wire it into a workflow enrollment trigger, fold it into lead scoring, or pull it into a report.
What It Touches in Your HubSpot Strategy
Custom Signals isn't a single-tool feature. It's an input layer that runs underneath several systems at once. Here's where the ripple effect lands.
Lead scoring gets a serious upgrade. Right now, most HubSpot lead scoring models reward behavior inside your own portal: page views, email opens, form fills. Custom Signals adds external buying behavior as a scoring dimension. A company posting a hiring surge in your buyer's job function is worth points. Wire that signal directly into your score.
Key Takeaway
Custom Signals can feed lead scoring with real-world buying triggers, not just portal engagement. That's a meaningful shift from reactive scoring to proactive scoring.
Workflow automation becomes event-driven in a new way. When a target account matches your custom signal, you can enroll them in a sequence immediately. Assign a task to the rep. Send an internal Slack alert. Update a CRM property. The trigger is the buying moment, not a form fill that happened three weeks ago.
If you're already building more sophisticated automation chains, pairing Custom Signals with HubSpot's ability to reference records created mid-workflow means you can spin up a new deal record the moment a signal fires and populate it with context in the same flow.
Segments get sharper. Instead of targeting "all companies in manufacturing with over 200 employees," you can target "all companies in manufacturing with over 200 employees who filed a vendor RFP in the last 30 days." That's a different conversation than a cold outreach to a static list.
Reporting now reflects signal performance. You can track which custom signals generate the most pipeline, which ones lead to closed deals, and which ones were noise. That feedback loop lets you refine your signal library over time.
Key Takeaway
Custom Signals work best when they're connected to the rest of your HubSpot stack: scoring, workflows, segments, and reports. Activating a signal and not wiring it into automation is leaving the feature half-used.
Third-party intent tool consolidation is now a real conversation. If you're paying for a standalone intent platform that feeds data into HubSpot anyway, Custom Signals gives you a reason to audit that spend. The case for consolidation gets stronger when the signals live natively in the CRM where your team already works.
This update also fits into a bigger picture. HubSpot has been building aggressively toward a native intent layer. If you want the strategic context behind that direction, our breakdown of what HubSpot's acquisition of Warmly actually means for your portal is worth reading alongside this one.
Who Should Care Most
Not every HubSpot customer needs to act on this immediately. Here's who should move first.
- Revenue operations leaders who own lead scoring models and want to add external buying triggers to an existing score without rebuilding from scratch.
- Sales managers at companies with long deal cycles and niche ICPs. If your buyers show up in specific, trackable ways (RFPs, regulatory filings, hiring patterns), Custom Signals was built for you.
- Marketing ops humans who manage enrollment triggers. Custom Signals opens a new class of workflow trigger that didn't exist before: real-world events instead of portal behavior.
- B2B companies spending on a standalone intent platform. This is the right moment to audit whether that tool still earns its seat at the table.
- Sector-specific businesses in education technology, government contracting, climate tech, or any vertical where buying signals are public but unusual. These humans have always been underserved by generic intent tools.
George's Take
I've audited a lot of HubSpot portals where the lead scoring model was built entirely on things that happened inside the portal itself: pages visited, emails opened, forms submitted. That's fine as a starting point, but it misses everything happening in the real world. A company quietly shopping your category, posting jobs that signal a budget approval, filing a public document that says "we're about to buy something." Custom Signals finally brings that external layer into HubSpot natively, and it does it without requiring humans to become prompt engineers or data scientists to get value from it.
“The best buying signals rarely happen on your website. They happen in the world. Custom Signals is HubSpot finally watching the world for you.”
This is also a clear signal (no pun intended) of where HubSpot's agentic platform is heading. If you want the bigger picture on that direction, our full guide to the HubSpot agentic platform breaks down what's available today and where it's going.
If you want help defining the right signals for your ICP, wiring them into your lead scoring model, and building the workflows that fire when a match hits, that's exactly the kind of work we do at Sidekick Strategies. Book a strategy call and we'll map it out together.
Frequently Asked Questions
What are Custom Signals in HubSpot Buyer Intent?
Custom Signals let you describe a buying trigger in plain language, such as a competitor hiring surge or a public RFP filing, and HubSpot's AI monitors the web to surface companies that match. Each match includes source citations. You can use custom signals in segments, workflows, lead scoring, and reports.
Who has access to HubSpot Custom Signals?
Custom Signals are available to all HubSpot customers with HubSpot credits. You access them through the Buyer Intent app under the Signals tab, then "My Signals." Check your portal's credit balance before setting up multiple signals, as credit usage may vary based on the number of active signals and matches.
How is a Custom Signal different from HubSpot's standard buyer intent signals?
Standard HubSpot intent signals track predefined categories like competitor visits or pricing page activity. Custom Signals let you define the trigger yourself in plain language. You're not choosing from a list; you're describing a niche buying moment specific to your business, and HubSpot finds companies that match it.
Can Custom Signals trigger HubSpot workflows automatically?
Yes. Once a custom signal is active, you can use it as a workflow enrollment trigger. When a company matches your signal, HubSpot can assign a task to a rep, send an internal notification, update a CRM property, enroll the contact in a sequence, or any combination of those actions.
Can Custom Signals replace a third-party intent tool?
For many businesses, yes, especially if you were using a standalone intent platform primarily to feed signals into HubSpot workflows. Custom Signals are CRM-native, cited, and connected directly to scoring, segmentation, and automation. The consolidation case is strongest for teams with niche ICPs and specific, trackable buying triggers.
How do I know if a Custom Signal is working before I activate it?
HubSpot generates a preview of matched companies before you activate any custom signal. You review that list to check whether the signal is too broad or too narrow, then refine your plain-language description until the preview matches your actual ICP. Source references are included so you can verify each match.
