Kaspr vs. Seamless.AI

Last updated on

Reviewed by Paddy Stobbs

PS

Kaspr and Seamless.AI serve distinctly different prospecting needs, with Kaspr excelling as a LinkedIn-centric prospecting tool while Seamless.AI offers a more comprehensive database-driven approach.

Kaspr is better suited to small teams with low monthly prospecting volume who primarily source leads through LinkedIn, offering superior LinkedIn integration and bulk list creation features. Conversely, Seamless.AI better serves moderate-volume teams needing broader prospecting capabilities beyond LinkedIn, with its extensive contact database, intuitive interface, and comprehensive company profiles. Neither tool offers complete sales engagement functionality, requiring integration with dedicated outbound platforms.

Advantages of Kaspr

Kaspr is significantly better at LinkedIn prospecting
We found Kaspr's LinkedIn integration to be more sophisticated than Seamless.AI's, with powerful features like bulk list creation from LinkedIn searches and one-click lead creation. This is particularly valuable for sales teams heavily focused on LinkedIn-based prospecting who need to quickly build targeted lists from LinkedIn's search filters.

Advantages of Seamless.AI

Seamless.AI offers a more comprehensive contact database than Kaspr
While testing, we found Seamless.AI provides one of the largest contact databases in the market with comprehensive search capabilities. Unlike Kaspr, which lacks a traditional database search interface and relies solely on LinkedIn-based prospecting, Seamless.AI offers robust filtering options and company coverage.
Seamless.AI is significantly easier to use than Kaspr
We found Seamless.AI's interface to be notably more intuitive and user-friendly, with an average SMB employee able to master it in under 15 minutes. In contrast, Kaspr's unusual interface requires several hours of familiarization and features a confusing onboarding process centered around Chrome extension installation.
Seamless.AI offers better sales engagement platform integration than Kaspr
We found Seamless.AI integrates with major sales engagement platforms like Outreach and Salesloft, which Kaspr doesn't support. This is particularly valuable for teams using these platforms for outbound campaigns.

Kaspr is best for

  • Businesses with a low prospecting volume (50-200 leads per month)
  • Who need LinkedIn-centric prospecting and require powerful Chrome extension functionality for bulk lead creation
  • And/or who want basic CRM integration capabilities with Salesforce, HubSpot, and Pipedrive

Seamless.AI is best for

  • Businesses with a moderate prospecting volume (200-1000 leads per month)
  • Who need an intuitive prospecting interface with granular filtering options and some AI research functionality
  • And/or who need access to a particularly large contact database (1.3B records)

Kaspr is less good for

  • Businesses with high prospecting volume (1000+ leads per month) who need a traditional database search experience
  • Who need advanced sales engagement features like email sequencing, tracking, and AI-powered personalization
  • And/or who need deep company insights including intent signals, tech stack data, or org charts

Seamless.AI is less good for

  • Businesses with high prospecting volume (1000-5000 leads per month) who require advanced workflow automation and territory management
  • Who need comprehensive sales engagement features like email sequencing, tracking, and meeting scheduling
  • And/or who need enterprise-grade features like API access, lead scoring, and custom contact fields

Functionality

2/10

<p>Kaspr is best viewed as a LinkedIn centric lead generation tool. Unlike most of its competitors, it lacks a traditional database search interface for both individual contact or companies. Instead, the only way to prospect is via their Chrome extension which acts over LinkedIn, or by enriching a CSV of LinkedIn URLs. As such, many common features and filters are omitted entirely. Additionally, Kaspr does not provide any native outbound sequencing functionality, meaning that you'll need to pay separately for a dedicated outbound platform too.</p>

Functionality

4/10

<p><span style="color: rgb(0, 0, 0);">Seamless.AI is best viewed as a lead generation platform as opposed to a rounded lead generation platform. When it comes to prospect search, its database is one of the largest on the market and its prospecting interface covers all the basic filters you'd expect. However, adjacent features around email engagement are omitted entirely meaning that you will need to pay for dedicated outbound tools separately. However, Seamless.AI do provide a email/message personalisation AI feature which integrates nicely across the product.</span></p>
Ease of Use

Ease of Use

4/10

<p>Despite, Kaspr's limited feature set, its unusual interface means that it takes slightly longer to get acquainted with on first use. On average, it would take an SMB employee a few hours to become comfortable with its core features. Whilst the Chrome extension itself is intuitive once installed, being forced to install it as step one of the onboarding process felt overwhelming and confusing.</p>

Ease of Use

<p><span style="color: rgb(0, 0, 0);">Seamless.AI's relatively limited feature set means that its web app is relatively easy to navigate. Its prospecting interface is familiar, intuitive and well designed. It would take an average SMB employee less than 15 minutes to master its use. </span></p>

Look and feel

4/10

<p>Kaspr's interface and design aesthetic is par amongst competitors. Whilst some pages are intuitive and well laid out (such as the leads list interface), others are overwhelming, cramped and confusing (such as the onboarding page). The design aesthetic feels a bit dated with excessive use of bright colours which feels distracting with extended use. However, when tested, we find page load times are fast and snappy.</p>

<p><span style="color: rgb(0, 0, 0);">Seamless.AI's web app is simple and easy to navigate. It's design aesthetic is minimalist, clean and modern - something which is rare amongst products in the space. Additionally, when tested, we find it's search pages and other interfaces were generally fast to load.</span></p>
Customisability
4

Customisability

4/10

<p>Kaspr lacks many routes of customisability that are common amongst its competitors, such as the ability to create custom fields for leads or manage/assign territories to specific sales agents. However, you are able to create custom workflow automations and create targeted lists off the back of these automations.</p>

Customisability

4/10

<p><span style="color: rgb(0, 0, 0);">Seamless.AI offers only a handful of channels for customisation. Beyond the ability to create targeted lists, there is also the ability to create custom searches. Additionally, businesses can provide their AI with a description about their objectives which will be used when drafting email suggestions. However, we were disappointed to see some enterprise friendly features omitted, such as the ability to manage/assign regions to agents. </span></p>
Ease of Setup

Ease of Setup

7/10

<p>Kaspr offers a self-serve free trial for their platform. When tested, we found the initial setup to be simple (taking &lt;10 mins). However, we did find the setup process to have a moderate amount of friction as you are forced to immediately download their chrome extension in order to use the product.</p>

Ease of Setup

8/10

<p>Seamless.AI offers a simple, self-serve free trial for their platform. When tested, we found the initial setup to be very simple (taking &lt;5 mins). Additionally, the lack of any native email sequencing functionality means it doesn't take long to get the most out of the platform either.</p>
Customer Support

Customer Support

7/10

<p>You can contact Kaspr's support agents via a live chat widget inside their web app. When tested, we find it extremely easy and quick to contact a real agent, often taking less than 2 minutes. Once contacted, support agents were responsive and helpful. Additionally, Kaspr offers a details help centre which is able to answer most basic questions.</p>

Customer Support

3/10

<p>On Seamless.AI's Free and Basic plans, we were disappointed to find that there was no live chat option made available - this is a feature gated to higher plans only. Instead, the primary channel for customer support is via email. When tested, we find responses to take roughly 24 hours. Additionally, their help centre is hard to navigate and articles were often lacking in depth.</p>
