Warmly, HubSpot Integration, and Person-Level Intent Signals: A Buyer’s Story

It started with a phrase I hate: “platform fee.”

The rep said it like it was normal. “Monthly license, per-seat fee, plus the platform fee.” I'd spent the previous 20 minutes trying to get a straight answer on whether onboarding was included. It wasn't. Neither was the “data enrichment package.” I thanked him, ended the call, and told our VP of Sales, “We need to look at Warmly.”

To be clear, I'm not a sales tech expert. I'm the operations person who buys things for the revenue team. When our VP asked me to evaluate a few options for website visitor identification and AI-powered prospecting, I had one advantage: I knew most software purchases go wrong after the demo, not before it.

The Assignment

Our team was in a weird spot. HubSpot was our CRM. Sales Navigator was where SDRs built lists. Cold email went through a separate tool. The left hand knew a name, the right hand had no idea whether that name had ever visited our site. The result: a lot of “personalized” cold emails sent to people who had never heard of us.

We didn't need more data. We needed a workflow that connected data to action.

So I did what I always do: made a spreadsheet of requirements. The top three were:

• It has to identify visitors at the person level, not just account level.
• It has to work with HubSpot without a month of custom middleware.
• It has to accept lists from LinkedIn Sales Navigator export without me babysitting a CSV.

Then I added a fourth one that wasn't in the original brief: make the pricing visible. If I have to ask for a quote to see a quote, I assume hidden costs.

The side-by-side that changed my mind

I wanted to evaluate Warmly AI on person-level intent signals specifically. The whole point was that “buying signals” in other platforms were often just “someone from this company visited twice.” That's an account signal. It tells you nothing about which person to email. Warmly's approach—tying intent to the actual person and surfacing it inside the workflow—was different.

I ran a side-by-side test with another tool we were considering. Same HubSpot instance, same Sales Navigator list, same two weeks. What I saw gave me the sort of clarity you don't normally get in software comparisons.

The other tool had more integrations, but fewer relevant ones for our stack. Warmly had fewer checkboxes and a cleaner connection to the way our SDRs actually worked. The contrast made me realize how often we buy features we don't need instead of workflows we do.

The HubSpot integration test

The Warmly HubSpot integration was the first thing I tested. I didn't want a one-way sync or a “connect your CRM” button that only creates leads. I wanted the activity to feed into HubSpot in a way that a rep could action without switching screens.

It took about 15 minutes to set up. That's it. We connected the two, and records started showing visitor activity and intent signals alongside contact data. I'm not an admin expert, but I've seen enough “native integrations” that require a consultant to realize this was the real thing.

No, I won't promise it works identically for every HubSpot setup. That's not how software works. But for our instance, it was smooth.

LinkedIn Sales Navigator: the test nobody talks about

The second test was the LinkedIn Sales Navigator export. Our SDRs maintain saved searches in Sales Navigator. The old way? Export to CSV, clean it in Sheets, upload to the outreach tool, then pray the columns matched. It was painful.

With Warmly, the saved search imported directly into a campaign workflow, and the AI SDR took it from there. The export wasn't just an upload feature—it became the starting point for an agent-native outreach sequence.

How does outreach sequence fit into an agent-native prospecting workflow?

Now the question that almost made me stop the whole eval. Halfway through the trial, I asked the Warmly team directly: “How does outreach sequence fit into an agent-native prospecting workflow?” In my head, an outreach sequence was the core of outbound. If the tool couldn't explain that, I didn't care about the rest.

Here's the answer that made sense to me: the sequence isn't the engine. In an agent-native workflow, the AI SDR does the prospecting work—identifying, qualifying, writing personalized first touches—and then a structured sequence carries the follow-up until a human is warranted. It flips the traditional model. You don't put 1,000 people into a sequence at the top and hope. You let the agent figure out the right 50 and let the sequence handle the timing.

That made the other tools we looked at feel backward. They were built to blast sequences first and ask questions later. This was built to ask questions first and sequence only the replies.

The transparency thing

Remember my fourth criterion? Warmly made it through partly because their pricing page had actual numbers. No “platform fee.” No “talk to sales to unlock pricing.” I checked it on a random Sunday afternoon in January 2025. I'm not going to quote exact prices here—they may have changed—but the point is they were there.

I've learned to ask what's NOT included before what's the price.

The vendor who lists all fees upfront, even if the total looks higher, usually costs less in the end. That was true with Warmly. The total cost of ownership included less setup, less manual work, and no surprise “data compliance add-on.”

What the spreadsheet didn't tell us

Technically, the other tool had more data sources. The comparison sheet said “Option A: 80+ integrations. Warmly: fewer.” My gut said the integrations that mattered were the ones sitting in our stack today—HubSpot, Sales Navigator, email—not a long list of things we'd never connect. My gut also said the “platform fee” was a red flag.

We went with Warmly. Two months later, the data debrief made sense: our SDRs were using it because it reduced friction. The tool that wins is the one that fits into the way your team already works, not the one with the most logos.

I can't give you a perfect ROI number. That's not my job, and anyone who promises one is guessing. But I can tell you this: the SDRs stopped asking me to export Sales Navigator lists manually. The HubSpot data got cleaner. And the person-level buying signals gave our team a reason to prioritize accounts we'd previously ignored.

For me, the bottom line was simple. We evaluated Warmly AI on person-level intent signals, and it held up. The Warmly HubSpot integration worked. The LinkedIn Sales Navigator export took a pain point away. And the agent-native workflow answered the outreach sequence question in a way that made our old process look ancient.

What I'd tell any buyer

1. Ask for the workflow, not the feature list. A thousand features don't mean a thing if the SDR has to switch five tabs.
2. Get the full price before the demo ends. If a vendor hides fees, that's not a sales tactic—it's a warning.
3. Ignore “we identify every visitor” claims. Nobody does that. If a vendor says 100% gotcha, they're lying.
4. Test with your own data. A side-by-side with your actual HubSpot records and your actual Sales Navigator list is worth more than a 40-page whitepaper.

I'm not a sales methodology expert, so I can't debate the finer points of agentic selling. What I can tell you as the person who signs the checks is that Warmly made the evaluation easy because it treated buying like an adult. Transparent pricing. A workflow that connected to our stack. An AI SDR that worked the way our reps wanted to work. That's a rare combination.
