6sense Alternatives: 9 Competitors Compared by Price and Use Case (2026)

The median 6sense buyer pays $62,440 a year, according to Vendr's data from 385 purchases, with contracts ranging from $11,376 to $176,809. And the free way in is gone: 6sense discontinued its free Sales Intelligence plan on August 12, 2026, so every evaluation now runs through a sales-led quote. Several popular comparison posts still mention a free tier, so check the date on anything you read.

If that price, the setup effort or the account-level focus doesn't fit your team, there are good alternatives. Some replace the whole platform, and others replace just the part of 6sense you actually use. This guide compares 9 options by price and use case and explains how to choose.

What kind of tool is 6sense?

6sense is a revenue intelligence and account-based marketing (ABM) platform. It identifies companies visiting your website anonymously, predicts which accounts are in-market and at what buying stage, and helps you target them with ads, email and sales alerts.

Its intent data comes from two places. 6sense tracks research activity across its own network of B2B websites, and it also resells third-party intent from partners. According to Parsley's comparison, 6sense names Bombora, G2, TrustRadius, PeerSpot and TechTarget as partner sources. That matters when you compare alternatives, because some of the same signals are available more cheaply on their own.

Why teams look for a 6sense alternative

• Price and lock-in. Beyond the platform fee, Vendr says implementation can add $10,000 to $50,000 or more, and contracts often include annual price increases of 5% to 10%.
• Setup effort. The predictive models work best with clean CRM history, and most buyers need a RevOps owner to configure and maintain the platform. UserGems reports that many teams wait three to six months for the platform to become fully useful.
• Accounts, not people. 6sense tells you which companies are researching. Your reps still need to know who to contact and how to reach them.
• Noisy signals. Even 6sense's own head of research, Kerry Cunningham, wrote that most of what's sold as intent data is just a short spike of interest. He argues those spikes should trigger marketing, not SDR calls.

6sense alternatives at a glance

The 9 best 6sense alternatives

1. Demandbase: the closest like-for-like replacement

Demandbase is 6sense's most direct competitor, covering account identification, intent data, advertising, website personalization and sales intelligence in one platform. Its biggest structural difference is a native B2B demand-side platform (DSP), so account-based ads run inside the product rather than through a partner. Parsley notes that both vendors resell some of the same intent sources, including Bombora, G2 and TrustRadius.

Price: Vendr's Demandbase data shows a median of $68,591 a year across 187 purchases, from $24,000 to $164,037. That's close to 6sense, so price is rarely the deciding factor between the two.

Best for: Enterprise teams where account-based advertising is a primary channel.

2. Bombora: intent data without the platform

Bombora sells intent data on its own. Its Company Surge product flags companies researching a topic more than usual, based on a data co-op of publishers and B2B sites. According to Bombora, it tracks more than 25,300 intent topics, and 86% of its co-op data is shared exclusively with Bombora. Many other platforms on this list resell Bombora data, so you may already be paying for it indirectly.

Price: Prospeo's intent data guide puts the Vendr median at about $24,750 a year.

Best for: Teams that already have a CRM, marketing automation and sequencing tools and just want the signal.

3. ZoomInfo: contact data plus intent

ZoomInfo approaches the category from the data side: a very large contact database, with intent signals, website visitor tracking and sales engagement added on. If your reps need direct dials and verified emails as much as they need intent, it covers both in one contract. Prospeo notes that intent signals aren't included in ZoomInfo's entry tier.

Price: Vendr's median is about $33,500 a year. See our ZoomInfo pricing guide for the tiers.

Best for: Sales-led teams that want contacts and intent from one vendor.

4. G2 Buyer Intent: review-site signals

G2 Buyer Intent shows which companies are researching your category, viewing your G2 profile or comparing you with competitors. Because it captures comparison behavior, it tends to indicate later-stage interest than topic research does.

Price: Quote-based.

Best for: Software companies with an active G2 presence.

5. RollWorks (AdRoll ABM): ads on a mid-market budget

RollWorks focuses on account-based advertising, with intent from Bombora and G2 plus account and contact scoring, according to Influ2's comparison. It has less predictive depth than 6sense but is faster to set up.

Price: About $12,000 to $50,000 a year for mid-market teams, according to Salesmotion's ABM pricing comparison.

Best for: Teams new to ABM whose main need is targeted ads.

6. Terminus (DemandScience): multi-channel ABM

Terminus, now part of DemandScience, combines display, LinkedIn ads, email and web personalization with content syndication. It's stronger at reaching accounts you've already chosen than at predicting which ones are in-market.

Price: About $18,000 to $87,000 a year per Salesmotion, which cites a median near $23,000.

Best for: Teams with a defined account list that need multi-channel activation.

7. Apollo.io: contacts and outreach on a small budget

Apollo combines a large contact database with email sequencing, a dialer and basic intent filters. Bombora lists Apollo as a featured integration partner, but Prospeo notes Apollo's own intent filters cover only a few topics. It isn't an ABM platform, but for sales-led teams it covers list building and outreach for a fraction of the cost.

Price: Free plan; paid plans from $49 per user a month billed yearly. See our Apollo pricing guide.

Best for: Small and mid-sized sales teams running outbound.

8. Leadfeeder (formerly Dealfront): website visitor identification

Leadfeeder, which rebranded from Dealfront in 2026, identifies companies visiting your website and adds European company and contact data. If your main use of 6sense is knowing which accounts are on your site, it covers that for far less.

Price: Free plan available; Vendr's median is about $8,628 a year.

Best for: Teams with steady website traffic, especially in Europe.

9. Spona: buying signals plus verified leads

Spona turns buying signals into reachable, verified leads. You describe your ideal customer in a chat, and Spona's AI mines 40+ data sources, finds matching companies and decision-makers, validates each lead and scores it with the reasoning behind the match. Signal leads cost 100 to 500 credits, at $0.008 to $0.01 a credit, and you see free samples and a per-lead price before you buy.

Best for: Teams that need verified contacts at in-market accounts without an annual platform contract.

Is Demandbase similar to 6sense?

Yes. They're the two closest competitors in enterprise ABM, with similar features, overlapping intent sources and median prices within about 10% of each other. Parsley found the practical differences are architectural: 6sense's core is its predictive buying-stage model, trained on your own wins and losses, while Demandbase's core is its native advertising platform. If ads are a major channel, Demandbase has the edge. If predictive scoring matters more and your CRM history is clean, 6sense does.

Is 6sense similar to ZoomInfo?

Only partly. Both offer intent data and contact information, but they start from opposite ends. 6sense is built around predicting which accounts are in-market for marketing-led ABM, while ZoomInfo is built around a contact database for sales prospecting. Vendr's 6sense page estimates ZoomInfo's marketing platform at a lower base price for similar account volumes, and ZoomInfo bundles more contact data.

6sense vs. Bombora: platform or data feed?

This is one of the most common comparisons, and the two aren't really the same kind of product. Bombora is a data provider: it tells you which companies are researching which topics, and you act on that in your own CRM, marketing automation and ad tools. 6sense is a full platform that resells Bombora data alongside its own signals, then adds predictive scoring, advertising and sales alerts on top.

So the question is whether you need the platform layer. LinkedOtter's comparison suggests that teams spending heavily on 6sense without clear pipeline results often do better with Bombora plus their own first-party signals, such as event attendance and website visits. If you lack the operations capacity to act on raw signals, though, the platform may be worth paying for.

When 6sense is still the right choice

An alternative isn't always better. 6sense tends to earn its price when:

• You run marketing-led ABM across thousands of accounts with a dedicated operations owner.
• You have several years of clean closed-won and closed-lost data to train its predictive model.
• You want identification, intent, advertising and sales alerts in one place rather than stitching tools together.

If two or more of those don't describe you, one of the alternatives above will probably deliver more for less.

How intent data sources differ

Before you pick a replacement, check which kind of signal you're actually buying:

How to choose a 6sense alternative

1. List what you actually use in 6sense. Many teams use only website identification, intent alerts or ads. Replace that part, not the whole platform.
2. Decide whether you need accounts or people. If reps need someone to call, budget for contact data as well as signals.
3. Price the whole stack. A cheaper signal feed still needs enrichment, sequencing and someone to run it.
4. Test on real accounts. Run each finalist against accounts you've already won or lost and see whose signals would have flagged them.
5. Check contract terms. Look for notice periods, renewal increases and whether unused credits roll over.

How to get value from intent data, whichever tool you choose

Forrester's list of common intent data mistakes is a useful checklist:

• Don't treat a signal as a qualified lead. Intent should prioritize outreach, not replace qualification.
• Account for decay. Intent is time-sensitive; an old surge is noise.
• Combine sources. Varied signals are more predictive than one feed, as long as they aren't duplicates.
• Use your first-party data. Your own website and product activity is often the strongest signal you have.
• Keep your own lawful basis. Forrester warns that relying on a vendor's privacy compliance isn't enough.

If you're staying with 6sense: negotiate

Vendr reports buyers save about 17% on average. 6sense's fiscal year ends January 31, so the end of a quarter, and especially January, gives you the most negotiating power. Ask for a cap on renewal increases, credit rollover and a written list of what implementation includes, and get quotes from Demandbase or another alternative before you sign.

Spona: from signal to conversation

Intent tells you which accounts are researching. Spona helps you reach the people who matter at those accounts.

• Plain-language targeting: describe your ideal customer and the buying signals you care about in a chat, and get leads in about 4 minutes.
• Verified and scored: Spona states its leads are 95% accurate, with reasoning behind each match.
• No platform contract: free samples and a per-lead price first, then pay as you go. Bulk leads cost about $0.01 to $0.09 each, and qualified, scored leads about $0.32 to $4.00.
