6sense vs KeepSync: Feature Comparison for B2B Sales Tools

FOR HUBSPOT TEAMS
Track Job Changes at 1/10th the Cost
KeepSync monitors your HubSpot contacts for job changes with 94% accuracy. Free for up to 1,000 contacts. No annual contracts.
Request Early Access →6sense leverages its Signalverse™ system to process an astounding one trillion signals daily [6]. These signals include anonymous website visits and keyword searches across a wide network of B2B publishers. The platform draws from three key types of intent data:
Its 6signal Graph tracks 4 billion IP addresses, enabling it to link anonymous web activity back to specific companies [4]. By combining AI and natural language processing, 6sense provides a buying stage score - ranging from Target to Purchase - helping you pinpoint exactly where accounts are in their buying journey [5][7]. Additionally, it offers scoring for Account and Contact Fit, as well as In-Market likelihood, ensuring your outreach efforts are directed at the right opportunities [5].
This method is tailored for Account-Based Marketing (ABM). Instead of passively waiting for potential customers to fill out forms, 6sense identifies companies actively researching solutions, often months before they engage with vendors.
"Would you rather spray and pray, wasting resources, or target somebody who's raising their hand? That's the 6sense difference."
- Chris Kein, KBX Logistics [6]
While 6sense excels at analyzing anonymous intent signals, KeepSync takes a more personal approach by focusing on individual relationships, offering a complementary tool for sales teams.

Unlike the data-heavy approach of 6sense, KeepSync zeroes in on individual contacts - such as former champions, power users, or closed-lost prospects - and notifies you when they take on new roles. By cross-referencing over 30 data sources weekly and incorporating human verification, KeepSync achieves an impressive 94% accuracy rate.
When a tracked contact transitions to a new company, KeepSync sends real-time alerts through Slack, email, or HubSpot. These alerts include verified details like their updated email, phone number, and company information. This gives you a "warm" entry point into a potential account, as you're reconnecting with someone who already knows and trusts your brand.
The emphasis here is on relationship-driven growth. Instead of chasing anonymous signals, you're leveraging established relationships to uncover new opportunities. With its native integration into HubSpot, KeepSync allows these job change events to trigger automated workflows, update lead scores, or create targeted sales segments [3]. This approach turns existing trust into a new sales pipeline, eliminating the need to start from scratch with cold leads.
Choosing the right tool for your sales automation strategy depends on understanding the strengths and focus areas of each option. While 6sense excels at uncovering hidden demand, KeepSync (Job Change Tracking) highlights relationship-driven opportunities.
| Feature | 6sense | KeepSync (Job Change Tracking) |
|---|---|---|
| Primary Signal Type | Intent & behavioral (e.g., research patterns, keyword searches) | Relationship & milestone (e.g., career transitions) |
| Data Sources | Signalverse (1 trillion signals daily), 4 billion IP addresses, B2B publishers, review sites [6][4] | 30+ professional data sources with human verification |
| Accuracy | AI-powered predictive modeling with a 25%+ higher match rate [1] | 94% accuracy through multi-source verification |
| HubSpot Integration | Native bi-directional sync, embedded iframes, automated field updates [1] | Real-time alerts, workflow triggers, and 5-minute setup |
| Setup Time | Multi-month rollout with significant admin involvement [10] | Ready to use in days with minimal effort [10] |
| ROI Timeline | Takes months to establish a strong ABM motion [1] | Delivers results in days to weeks by targeting warm leads [9][10] |
| Pricing Model | Enterprise credit-based model ($50,000–$60,000+ annually) [9][10] | Transparent monthly plans starting at $149/month |
| Target Use Case | Account-Based Marketing (ABM), identifying unknown demand in large TAMs [10] | Warm outbound selling, relationship-focused sales, and churn prevention |
This table highlights where each tool fits into your sales strategy. 6sense is ideal for teams focused on identifying prospects researching solutions before they fill out forms. It uses predictive modeling to pinpoint accounts in the early stages of interest, helping prioritize efforts on a smaller, in-market segment. On the other hand, KeepSync notifies you when existing contacts change roles, offering a warm entry point into accounts and creating opportunities for relationship-driven sales.
Implementation and return on investment (ROI) timelines also set these tools apart. 6sense requires a significant investment and a multi-month setup, making it better suited for large organizations with complex ABM needs. Meanwhile, KeepSync provides a faster, more accessible solution with monthly pricing and quick deployment, making it a flexible option for teams of any size.
Turn to 6sense when you need to uncover accounts actively researching solutions in what’s often called the Dark Funnel. With 78% of B2B buyers defining their requirements before even reaching out to a seller [4], catching them during their research phase can give you a crucial early edge.
6sense shines in competitive scenarios by identifying accounts that are actively comparing options on third-party review sites. Considering that most buyers go with the first vendor they engage, getting in front of them early could make all the difference [4].
For complex deals involving 11 or more stakeholders [2], 6sense helps you zero in on the key decision-makers. For example, Auth0 saw a $3 million pipeline increase in just six weeks and a 25% bump in their average selling price [12]. Similarly, Showpad experienced a 289% increase in close rates by focusing on opportunities flagged by 6sense’s intent signals [12].
If you’re dealing with an overwhelming list of cold accounts, 6sense’s predictive scoring can help you prioritize. Instead of reaching out blindly, it identifies accounts that resemble past buyers - companies in the Awareness or Consideration stages - so your outreach is more targeted and effective.
While 6sense is excellent at reviving dormant accounts through predictive insights, KeepSync offers a complementary strategy focused on maintaining personal connections.
KeepSync complements 6sense by focusing on relationship-based opportunities to drive pipeline growth. It’s especially useful when reconnecting with established contacts can open doors.
The period immediately after someone transitions to a new role is particularly powerful. When a former customer or power user moves to a new company, they often arrive with a fresh mandate and budget. Reaching out within their first few months - before they’ve locked in vendor relationships - can give you a major advantage. Being the first to engage these buyers can significantly boost your chances of success [11].
Job change alerts also provide a natural way to revive stalled deals. If a deal previously fell through due to budget issues or internal hurdles, a new decision-maker can reset the conversation and create fresh opportunities.
KeepSync is ideal if you have a well-established database of former customers or unconverted leads. These contacts may not have been a fit in the past due to timing, budget, or company needs, but their new roles could completely change the game. With 94% accuracy and real-time notifications, KeepSync ensures you’re ready to act as soon as these high-value contacts move - long before your competitors catch on.
Additionally, automated tracking keeps your contact records up-to-date with new professional emails and titles, saving your team from chasing outdated information or dealing with bounced emails. With a quick 5-minute HubSpot setup and pricing starting at $149/month, KeepSync allows you to turn warm leads into opportunities almost immediately. This efficient approach not only improves outreach timing but also strengthens your overall sales automation efforts.

6sense links with HubSpot using a Sales Intelligence extension and CRM cards, allowing intent data to appear directly on company and contact pages within HubSpot’s interface [13][14]. This gives your sales team immediate access to details like account temperature, predictive scores, and technographic insights, all in one place.
You can map 6sense data into custom HubSpot fields by using mapping profiles [15]. Each HubSpot object - Account, Contact, or Lead - can have up to five mapping profiles, which let you assign key values like Account Temperature and Predictive Scores. These values can then trigger automated workflows.
When mapping, you have two options: choose "Fill if Blank" to keep manual entries intact or select "Override" to prioritize 6sense data [15]. The integration also supports Intelligent Workflows, which automatically enrich HubSpot records with firmographic and technographic data. It can even create new accounts and contacts based on anonymous intent signals [8][15]. This automatic data enrichment helps your team target leads more effectively and speed up the sales process.
You can set data syncs to occur in real-time, daily, or weekly. Real-time syncs are especially useful as they immediately trigger sales actions [16]. To access the 6sense Sales Intelligence Dashboard, make sure third-party cookies are enabled in your browser settings [14].
While 6sense focuses on enriching intent data through custom mapping, KeepSync takes a different approach by delivering immediate, relationship-driven alerts.
KeepSync offers a native HubSpot integration that takes just five minutes to set up. Once connected, KeepSync monitors contacts weekly across more than 30 sources, sending real-time alerts whenever a contact changes jobs.
These job change alerts can instantly trigger HubSpot workflows, update lead scoring, and generate lists [3]. For example, if a former champion moves to a target account, the integration can automatically create tasks for your sales team to reach out promptly. This ensures your team can act quickly on opportunities.
KeepSync also enhances contact records by adding verified professional emails, phone numbers, and updated company details. This eliminates the hassle of chasing outdated information. With a 94% accuracy rate and plans starting at $149/month for 5,000 contacts, KeepSync focuses on transforming warm leads into actionable opportunities. For those who want to test the waters, the Starter plan includes 1,000 contacts per month at no cost, making it easy to try out the integration with real data before committing to a paid plan.
Together, these integrations supercharge your HubSpot workflows by combining intent data and relationship signals, leading to more effective and automated sales processes.
6sense analyzes over 1 trillion signals every day to uncover which accounts are actively researching solutions - even if they haven't landed on your website. This provides broad, account-level insights. On the other hand, its job change tracking feature pinpoints when a known contact moves to a new company, offering more focused, person-level signals. Together, these insights can help refine your strategic investments.
When to Choose 6sense: If you're running large-scale ABM campaigns or want to uncover hidden demand before competitors, 6sense is a powerful choice. Its enterprise-level pricing starts at approximately $50,000 and typically requires multi-year commitments, but it delivers measurable ROI [9].
When to Choose KeepSync: For relationship-driven selling, KeepSync is ideal. It tracks when former champions or power users move to target accounts, giving you instant access to warm leads. The platform monitors contacts weekly across 30+ sources with 94% accuracy. Pricing starts at $149/month for 5,000 contacts, and it integrates seamlessly with HubSpot to automate workflows when job changes occur.
For a comprehensive pipeline strategy, combining these tools can be a game-changer. Use 6sense to identify and prioritize accounts showing intent, and layer in KeepSync's job change alerts to create warm, contact-level entry points. This dual approach ensures you're addressing both the 10% of your market that's actively searching for solutions and maintaining relationships that lead to faster conversions [4].
Whether you're looking to leverage existing relationships with job change tracking or break into new markets with predictive analytics, aligning your tools with your sales goals can significantly enhance your outcomes.
KeepSync and 6sense take distinct paths when it comes to identifying sales opportunities, each catering to different sales strategies.
6sense leans on predictive analytics and intent data to monitor account-level activities like website visits and ad interactions. This approach helps sales teams pinpoint accounts that demonstrate buying intent, making it a strong fit for account-based marketing (ABM) strategies.
In contrast, KeepSync zeroes in on tracking job changes within target organizations. By spotting role transitions, it delivers contact-level insights, allowing sales teams to engage directly with decision-makers at just the right moment. While 6sense highlights broader account-level trends, KeepSync takes a more individualized approach, focusing on specific leads experiencing job changes to enable precise and timely outreach.
Tracking job changes can be a game-changer for sales teams. When you identify contacts who've moved to new roles or companies, it opens the door to warmer outreach opportunities. These connections often lead to 2 to 4 times higher engagement rates compared to traditional cold outreach because they tap into existing relationships during key career transitions.
But that's not all. Keeping an eye on job changes can reveal new revenue streams, reignite deals that might have fallen through, and give your team a head start by connecting with prospects before competitors catch on. The benefits are clear: shorter sales cycles (by about 25–40%), improved win rates, and more precise, timely outreach. It's a strategy that can significantly boost your B2B sales efforts.
Integrating 6sense and KeepSync with HubSpot brings together valuable insights, making it easier for sales teams to work efficiently within a single platform. Here's how these tools make a difference:
When combined with HubSpot, these tools enable sales teams to automate and personalize their outreach strategies. Intent data reveals which companies are showing interest, while job change tracking highlights critical organizational shifts. This dynamic pairing ensures that outreach is both timely and relevant, helping teams prioritize leads, reduce manual effort, and ultimately improve conversion rates. Together, they simplify the sales process and strengthen pipeline management, delivering more effective results.
