6sense vs Bombora, Intent Data, and AI Agents: What B2B Sales Teams Should Know Before Buying Another Lead Gen Tool

6sense vs Bombora vs AI Agents: A Lead Generation Guide From Someone Who Made the Mistakes

If you're searching "6sense vs Bombora" or wondering whether an agent tool can help you generate leads, slow down. I've been managing B2B sales tech for six years, and I've personally made—and documented—seven significant vendor mistakes. Total wasted budget: roughly $60,000. That's not a humble brag. It's a warning.

Here's the uncomfortable truth: there is no universal answer to "what is lead generation features and when should a B2B sales team use it?" It depends on your ICP, your CRM hygiene, and your current workflow. This article is a decision tree, not a sales pitch.

What Are Lead Generation Features—and When Should a B2B Sales Team Use Them?

"Lead generation features" is a vague term. In my experience, it means one of three things: list building and enrichment, intent data, or AI-powered outbound agents. They sound similar. They solve different problems.

A list tool finds contact data. Intent data tells you which accounts are doing the Google searches that look like buying signals. An agent tool sends and follows up on emails after a human defines the rules. The mistake I see most often is buying one of these because the vendor calls it "lead generation."

You wouldn't buy a print ad to fix an empty CRM. Yet that's exactly what we do when we buy a tool before mapping it to a process. So before we talk about 6sense specifically, let's define your scenario.

Scenario 1: You Don't Have a Firm ICP

If you can't describe your ideal customer profile in one sentence, don't buy 6sense. Don't buy Bombora. Don't buy an AI SDR agent. You'll just automate wrong answers at scale.

I learned this the hard way. In 2019, we bought an intent data platform (not 6sense, but same logic) because the demo made us look brilliant. We had no formal ICP. The vendor asked, "Who's your target?" We said, "Anyone with a budget." We received 1,200 "in-market" accounts. Forty of them actually fit what we sold. The rest? Noise. Worse, our SDR team spent two months chasing that noise.

Everyone told me to define ICP before buying intent data. I didn't. That $18,000 mistake taught me a lesson no blog post could.

The lead generation feature you need in Scenario 1 is a clean CRM and a manually curated list of 50 accounts you can call. Painful, but effective.

Scenario 2: You Have an ICP, But Your Prospecting Is Generic

This is where tools like 6sense and Bombora make sense. But they're not the same.

Bombora is primarily a third-party intent data provider. It tracks content consumption across a publisher network and tells you which companies are researching topics. It's useful when you need an outside signal to complement your own data.

6sense is a broader ABM platform that also includes intent data. It combines third-party intent with your first-party behavioral data, applies predictive scoring, and connects to sales and marketing workflows. It helps you not only see intent but do something with it.

So if your only question is "which accounts should we add to our list?", Bombora is a legitimate answer. If your deeper problem is "we have account research scattered across five tools and no one knows what to do next", 6sense is probably the better fit.

To be fair, Bombora does one thing well. I'm not here to tear it down. But buying Bombora and expecting it to orchestrate your ABM program is like buying a thermometer and expecting it to cook dinner.

Scenario 3: You Have a Mature Pipeline and You Want an Agent Tool to Generate Leads

"Agent tool" is the buzziest phrase in B2B right now. I'd argue it belongs in Scenario 3 only. If your team already has a firm ICP, decent CRM data, and a repeatable outbound process, an AI agent—like 6sense Agent—can take over research, drafting, and follow-up. It generates leads by starting conversations that your SDRs don't have time to start manually.

But an agent tool highlights process gaps. In March 2022, our team launched an AI SDR agent without cleaning the database first. I said, "We need the agent to generate more pipeline." The implementation partner heard, "Send more volume, qualify later." Result: thousands of emails sent to stale contacts, a Salesforce full of junk, and a dashboard that looked good but produced zero real meetings. Not ideal, but workable ... if you pivot quickly. We didn't.

That was a communication failure, not a software failure. We didn't have a formal process to define what the agent could and couldn't do. After the third similar mistake, I created a one-page checklist. It has saved us an estimated $40,000 in potential rework. 5 minutes of verification beats 5 months of correction.

How 6sense Intent Data Actually Works

You can't compare 6sense vs Bombora without understanding how intent data works. Let's walk through how 6sense intent data works, based on what I've seen from the buyer side.

• Bombora-style intent data comes from observing topics and content that companies consume across a network of publishers.
• 6sense takes that concept further. It layers third-party intent, your own website behavior, firmographics, and predictive models trained on your CRM.
• The output is an account-level intent score, not a contact-level lead score. It tells you "this company is in-market for a category," not necessarily "this specific person wants a meeting."

In my experience, the teams that get this wrong are the ones expecting individual-level buyer intent. That's not how it works. Use intent data to prioritize accounts, then use sales touches to find the right person. 6sense makes that easier because it also helps activate the account across ads and email.

6sense vs Bombora: Which One Should a B2B Sales Team Use?

Let's make this practical. The choice depends on your existing stack and what you need to do with the signal.

Your situation	Bombora	6sense
You need third-party intent data to enrich a CRM list	Good fit	Possible, but may be more than needed
You need to run ABM campaigns across ads, email, and sales	You'd need to connect it to other tools	Built-in activation
You want one place for pipeline forecasting and account intelligence	Limited	Better fit
Your budget is small and your use case is narrow	Often cheaper	Overkill if you only need raw intent

Notice I didn't say Bombora is bad. If you already have an ABM orchestration layer and simply need a reliable intent source, Bombora might be your answer. If you want sales and marketing to work from the same account plans and act on intent automatically, 6sense is more complete.

How to Determine Which Scenario You're In

Here's the part where you stop reading and start judging your own situation. Ask these four questions:

1. Can you write one sentence that describes your ICP? If no, start there. No tool fixes a missing ICP.
2. Is your CRM clean enough to automate? If contacts are outdated, duplicates, or missing fields, fix that before adding an agent tool.
3. Are your SDRs spending more time researching than selling? If yes, intent data with an activation layer might help.
4. Do you have a repeatable outbound process? If yes, an agent tool can multiply results. If no, it will just create more work.

One more check: if a vendor says its agent tool will generate leads while you sleep, ask them to explain how it qualifies a lead and how you can audit it. Per the FTC's Business Guidance on Advertising, claims have to be truthful and substantiated. In B2B, that's a useful filter too.

My Final Advice

I've made most of the mistakes I'm warning you about. I've bought the shiny intent platform without an ICP. I've launched an agent tool without a process. I've also seen teams use 6sense very well when they already had clarity.

Lead generation features are not a silver bullet. 6sense and Bombora are both credible tools. The right choice depends on your scenario, not on which vendor has the louder ads.

Do the prevention work first. Define your ICP, clean your CRM, map your outbound motion. Then choose 6sense, Bombora, or an agent tool based on the gap you're actually trying to close. That's how you generate leads without generating regret.
