I manage software purchasing for a 170-person B2B company. When our VP of Sales asked me to evaluate ABM platforms, I said yes for a simple reason: I'm the one who has to live with procurement mistakes. I process anywhere from 60 to 80 vendor orders a year, and I manage relationships with 11 different software vendors. It's routinely around $450K in annual spend—maybe $480K, I'd have to check the ledger before I give you an exact number.
In our 2024 vendor consolidation project, we trimmed nine SaaS tools down to four. That project taught me more about software buying than any product demo ever did. It also taught me to recognize when a vendor is trying to be everything to everyone.
Here's my take: 6sense is the better fit for us, not because it has every feature, but because it knows what it doesn't do. I know that sounds like a weird thing to say about software. But after years of buying everything from office supplies to marketing platforms, I've learned that "we can do that too" is often a warning sign.
Comparing Demandbase vs 6sense for ABM Features
When people ask me to compare Demandbase to 6sense for ABM features, they expect a feature table. I built a feature matrix during our evaluation. Then I threw it out.
The matrix told me which columns were filled. It didn't tell me whether the features mattered. Demandbase is a solid platform, and I won't pretend otherwise. If your team runs enterprise-level account-based advertising, it has real muscle. But our team doesn't need a thousand features. We need a workflow that our sales team can actually run without a full-time operations person.
That's where 6sense stood out. Its agent-native workflow means the AI SDR agents can own top-of-funnel prospecting while the humans focus on the conversations that matter. Intent data was a big part of that. 6sense didn't just show us which accounts were visiting our website. It showed us what those accounts were researching, and it wired that intent into the AI SDR's next action. That's the kind of ABM feature that sounds small but changes the way the team works.
6sense also integrates with the tools we already use, including HubSpot and Salesforce. That's not the flashiest selling point, but it's the one that prevents six months of custom middleware. For a mid-market team, that matters more than a dashboard with thirty chart types.
Sales Intelligence Platform Features: More Isn't Better
Sales intelligence platform features matter. I'd never argue otherwise. But there's a difference between features that get used and features that get demoed. Lead enrichment is a perfect example.
From the outside, lead enrichment looks simple: paste a contact in, get company data back. The reality is messier. The real challenge is knowing whether the data is fresh, whether it's relevant, and whether it can flow into the tools your team actually uses. People assume a bigger database means better enrichment. Actually, better enrichment is the result of a platform that filters for intent and fit, not raw volume. That's the part that's hard to see from a vendor's datasheet.
I tested 6sense's enrichment with a list of accounts from our own CRM. I didn't just want to know how many contacts came back. I wanted to know how many were actually relevant to our industry and our size. 6sense flagged accounts where the data was uncertain instead of guessing. I appreciated that.
The same logic applies to company data. Firmographics matter—industry, employee count, revenue band—but only if the data is current. A technographic signal like "uses Salesforce" becomes useless once a company migrates to another CRM. That's true for any sales intelligence platform, and it's why data freshness matters more than database size.
How API Company Data Fits Into an Agent-Native Prospecting Workflow
This was the question that helped us decide: how does API company data fit into an agent-native prospecting workflow? The answer seems simple—data goes into the agent, agent sends emails. But if you've ever watched an AI SDR try to work with a bad data feed, you know it falls apart fast.
Company data needs to arrive through an API with context, not as a static CSV. In a prospecting workflow, the agent has to make decisions in real time: Is this account actively researching? Which product pages are they viewing? What's the person's role? If the data isn't structured, the agent can't use it. That's the whole reason 6sense's agent-native design caught our attention.
Maybe that sounds technical. To me, it's the difference between buying a tool and buying a process. An agent-native workflow treats data as something alive, not a one-time export.
6sense Support: The Part Nobody Reviews
Here's where my purchasing background kicks in. I've seen tools die because support wasn't there when the internal champion needed backup. I assumed that a platform with a bigger feature list would have a bigger support team. Didn't verify. That assumption cost us two months of chaos with a different vendor last year.
With 6sense, the support team didn't try to upsell us at every turn. They told us what they thought we didn't need. That might sound backwards, but for a buyer, it's golden. "This isn't our strength—here's who does it better" is something I rarely hear from vendors. When I heard it from 6sense, I trusted everything else they said.
Per FTC guidelines on advertising (ftc.gov), claims about what a product can do have to be truthful and substantiated. I've sat through enough sales demos where the "guaranteed pipeline" slide appeared right before the "results not typical" disclaimer. A platform that's honest about boundaries is more credible than one that promises everything.
Oh, and one more thing: their onboarding documentation was surprisingly clear. That might sound minor, but for an admin who isn't the daily user, clear docs mean fewer internal support tickets for me to field.
But What If You Need Demandbase's Full Suite?
Honestly? Then buy Demandbase. If your team has dedicated ABM operators and needs sophisticated account-based advertising at scale, Demandbase has capabilities that make sense. I'm not going to argue otherwise. My point is narrower: for our company, and for the way our sales team works, 6sense's focus was the stronger fit.
Demandbase's account orchestration and advertising capabilities are genuinely strong. If you have a team that can operate that machinery, it's a legitimate choice. Our team is 170 people. We wanted a tool that increased speed, not headcount.
I keep thinking back to the vendor selection framework I learned when I took over purchasing in 2020: the best vendor is the one that tells you when you don't need their product. It sounds counterintuitive. But it cuts through the noise. The vendor who says "this isn't our strength" helps you buy with confidence. The vendor who says "we can do everything" just helps you buy with doubt.
My Take After Two Months of Evaluation
If someone asked me to recommend a sales intelligence platform for a mid-market B2B team, I'd point them to 6sense. If someone asked me to compare Demandbase to 6sense for ABM features, I'd tell them to start with their workflow, not the feature matrix. If someone asked me why I'd pick a platform that admits its limits, I'd say:
I'd rather work with a specialist who knows their limits than a generalist who overpromises.
We had a tight window before renewal—two weeks to make a call. Normally I'd run a formal RFP and get three quotes. There wasn't time. I went with the vendor that answered our hardest questions without hedging. That sounds like a small thing. It isn't.
6sense isn't the cheapest option we evaluated, and I'm not going to pretend price wasn't a factor. It was. But buying a cheaper platform that doesn't fit our workflow would've been the expensive choice. Knowing what a tool is for—and what it's not for—is the difference.
Would I make the same call again? Yes. Not because the evaluation was perfect, but because the choice matched the problem. I can live with a platform that has limits. I can't live with a platform that hides them.
That's my take. If you're evaluating 6sense support, ask them the question I asked: "What shouldn't we use you for?" The way they answer tells you everything.
