6sense vs. Amplemarket

Last updated on

PS

Amplemarket and 6sense serve distinctly different needs in the lead generation market. Amplemarket excels as an all-in-one lead generation platform with powerful AI automation, multi-channel outreach capabilities, and an intuitive user interface, making it ideal for SMBs seeking to maximize the impact of smaller sales teams.

6sense, while offering a larger database and better enterprise security compliance, functions primarily as a basic contact database with intent signal tracking, better suited for larger organizations that already have established sales engagement tools and require strict security compliance.

Advantages of 6sense

6sense has a significantly larger contact database

With over 449M contact records worldwide, 6sense offers superior reach for teams needing extensive contact coverage. This is particularly valuable for enterprises requiring broad market coverage or those targeting niche segments where contact availability might be limited.

6sense offers more sophisticated intent scoring

6sense provides granular intent scoring across multiple dimensions, including account profile fit, buying stage prediction, and reach scores. This is particularly valuable for enterprise sales teams who need to prioritize accounts based on complex buying signals. We find this feature especially useful for teams that require a more nuanced approach to account prioritization.

Advantages of Amplemarket

Amplemarket is significantly more advanced in AI-powered automation
Amplemarket's AI sales co-pilot, Duo, stands out by autonomously discovering leads, crafting personalized outbound sequences, and executing them across both email and LinkedIn channels. This level of automation is particularly valuable for SMBs looking to maximize the impact of smaller sales teams. 6sense, in contrast, offers no automated prospect list building or AI-powered engagement features.
Amplemarket offers superior outbound campaign capabilities
While 6sense lacks any native email sequencing functionality, Amplemarket provides comprehensive outbound capabilities including email sequences, LinkedIn automation, and even the unique ability to send personalized voice messages via LinkedIn using your own cloned voice. This makes it particularly effective for teams pursuing multi-channel outreach strategies.
Amplemarket delivers a significantly better user experience

We find Amplemarket's interface to be more intuitive, with snappy performance that loads pages in under 1 second. In contrast, 6sense's interface is cluttered with technical jargon and suffers from slow page loads of up to 5 seconds.

6sense is best for

  • Businesses with a moderate prospecting volume (200-1000 leads per month)
  • Who need to identify in-market buyers through intent signals and need predictive analytics to score accounts
  • And/or who want a large verified contact database and already have a common CRM solution in place

Amplemarket is best for

  • Businesses with moderate to high prospecting volume (1000-5000 leads per month)
  • Who need autonomous AI-driven lead generation and outreach, with capabilities like voice cloning for LinkedIn messages
  • And/or who want comprehensive intent signal tracking with multi-channel outreach automation across email and LinkedIn

6sense is less good for

  • Businesses with low or very high prospecting volume who need advanced automation and engagement features
  • Who need streamlined workflows and intuitive user interfaces for high-volume prospecting
  • And/or who need comprehensive automation capabilities like workflow automation, automated list building, or email sequences

Amplemarket is less good for

  • Businesses with a very low prospecting volume (<50 leads per month)
  • Who need basic and focused contact lookup without AI-powered automation and personalization
  • And/or who want standalone sales engagement platform integration with tools like Outreach or Salesloft

Stackfix Verdict
Functionality

Functionality

4/10

<p>At its core, 6sense Revenue for Sales is just a contact database. While the predictive AI feature may help identify in-market buyers, the filtering options are rather standard. An exception is that you can track website engagement on 6sense to see how your prospects are engaging with you. Beyond that, there’s no additional functionality—you can’t even send emails directly from the platform.</p>
9

Functionality

9/10

<p>Amplemarket is not a standalone lead generation database. Instead it's an all-in-one lead generation platform that bundles a comprehensive database (300M contacts), an email/LinkedIn sequencing tool and rich signal tracking capabilities. It's AI sales co-pilot, Duo, is worth calling out as when tested, we found its capabilities to be particularly comprehensive. Despite requiring some initial setup to define personas and tracking signals, Duo can find leads, craft custom outbound sequences and execute on them, all autonomously.</p>
Ease of Use
3

Ease of Use

3/10

<p>For a tool with limited functionality, 6sense still manages to introduce unnecessary friction. The use of overly technical jargon like "Technographics" instead of "tech stack" or "Psychographics" instead of "keywords" feels needlessly complicated. Basic workflows, like creating a new list after bulk-selecting contacts, are clunky. Even small tasks, such as unlocking email details, require you to click on them one by one—a frustrating and time-consuming process.</p>
6

Ease of Use

6/10

<p>Amplemarket's interfaces are well designed and intuitive. It's core prospecting experience is familiar and easy to use. Additionally, its email sequencing tool is also well laid out and easy to grasp. However, importing contacts into sequences - a key workflow - is extremely clunky.</p>
Look and feel

Look and feel

4/10

<p>6sense is a functional, no-frills database. While the information is laid out clearly and organized well, performance is a letdown. Pages can take up to 5 seconds to load, which disrupts the overall experience.</p>
9

Look and feel

9/10

<p>When tested, we find Amplemarket to one of the best designed sales tools on the market. It's interfaces are minimalist, sleek and modern. We especially appreciated the keyboard shortcut options presented. When tested, its search pages were snappy and quick to load (often &lt;1 second) and any AI interfaces which required time were well presented with beautiful loading animations.</p>
Customisability
2

Customisability

2/10

<p>Customization options are extremely limited. The platform only allows you to create custom lists. You can’t add custom fields, save searches, or share searches with your team—basic features you’d expect from a tool like this.</p>
8

Customisability

8/10

<p>Amplemarket offers a wide array of channels to customise your experience. Most of these related to Duo, its AI sales copilot. To get the most out of the product, you're able to customise which buying/market signals are relevant to you, define personas &amp; ICPs and also provide clear definitions of you and your competitors (and where your edge lies).</p>
Ease of Setup
5

Ease of Setup

5/10

<p>Though 6sense gates most of its pricing tiers behind a sales call, they do offer a limited self-serve free trial with a limited range of features. When tested, we found the platform reasonably simple to set up and onboard into. Additionally, the lack of any kind of native outbound functionality means that there isn't much further integration or customization work that needs to be done either.</p>
3

Ease of Setup

3/10

<p>Frustratingly, Amplemarket does not offer a self-serve option to try out the platform. Instead, you’ll need to trudge through two sales demos before you are able to access their trial. Once access was granted, we found the platform very simple to set up initially, however, there are a lot of details you’ll want to customise (such as personas, competitors etc. for their Duo AI system) that can take several days to complete.</p>
Customer Support
4

Customer Support

4/10

<p>There’s no in-platform help, which is disappointing. 6sense claims to offer a support portal and help center through a separate site called RevCity, but we were shown an error message when attempting to login to the platform.</p>
4

Customer Support

4/10

<p>You can contact Amplemarket's customer support via a chat widget inside its web app. When tested, we found the initial AI chatbot to be unhelpful, and reluctant to pass over to a human agent. Multiple users also report dissatisfaction with the speed and helpfulness of Amplemarket's human agents. However, its help centre documentation and 'university' guides are very rich and well laid out, answering most questions we had about the product.</p>
Integratability
4

Integratability

4/10

<p>6sense offers native integrations with popular CRMs like Salesforce and HubSpot, as well as sales engagement platforms like Salesloft. However, it lacks key integrations with tools like Zapier or Outreach, which are widely used in sales workflows. While it does provide an API, relying on this for custom integrations may not suit every team.</p>
4

Integratability

4/10

<p>Amplemarkets array of integrations covers the basics. It offers integrations with major CRMs (Salesforce, Hubspot) as well as automation platforms like Zapier. We were also pleased to see an API that allows businesses to interact with Amplemarket's leads database directly. However, we would also liked to have seen integrations with external sales engagement platforms such as Salesloft or Outreach.</p>
Ease of Migration

Ease of Migration

7/10

<p>6sense allows you to export both contact and company data via self-serve functionality. It also offers a well-documented API for businesses that want to interact with its database programmatically.</p>
