Seamless.AI vs Uplead - Comparison 2025

Seamless.AI vs. Uplead

Last updated on

PS

Seamless.AI and Uplead both offer straightforward contact database solutions for small to medium-sized businesses and growing enterprises. Seamless.AI stands out as the superior choice in most scenarios, combining an excellent user experience with an extensive contact database of over 1.3 billion records.

While Uplead does provide comprehensive company data, it falls short of Seamless.AI in virtually every other aspect. However, neither platform offers robust native engagement or CRM capabilities, so businesses should plan to integrate them with dedicated CRM solutions for optimal results.

Advantages of Seamless.AI

Seamless.AI is significantly easier to use
We found Seamless.AI's interface to be notably more intuitive and user-friendly compared to Uplead. Its minimalist, clean design and fast-loading interfaces mean new users can master the platform in under 15 minutes, which is particularly valuable for SMB teams looking to quickly onboard new sales staff.
Seamless.AI has better automated list building
Seamless.AI's 'Autopilot' feature automatically generates prospect lists based on parameters, while Uplead lacks any automated list building functionality. This is especially useful for teams wanting to maintain a consistent pipeline of fresh prospects without manual intervention.
Seamless.AI offers a much larger contact database

Seamless.AI boasts a contact database with over 1.3 billion records, much larger than that of Reply's - making it better suited to businesses who need to prioritise breadth and coverage

Seamless.AI has superior security compliance
Seamless.AI maintains SOC 2 Type II compliance, which Uplead lacks. This makes Seamless.AI a better choice for enterprise customers or those working with sensitive data who require robust security certifications.

Advantages of Uplead

Uplead is significantly better at customer support
We find Uplead's customer support to be notably superior, with quick access to live chat support and helpful first-response resolution. In contrast, Seamless.AI's support is primarily handled through email, which can be frustrating for teams needing immediate assistance.
Uplead offers more comprehensive company insights
When testing company profiles, we find Uplead provides richer context including fundraising history, technology stack, competitors, and recent news flow. Seamless.AI's company profiles, while extensive in number, lack this depth of contextual information which is valuable for sales teams conducting account research.

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)

Uplead is best for

  • Businesses with a moderate prospecting volume (200-1000 leads per month)
  • Who need granular contact and company filtering capabilities across a reasonably large database of 160M+ leads
  • And/or who want basic, no-frills lead generation features to complement existing CRM and engagement tools

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

Uplead is less good for

  • Businesses with high prospecting volume (1000+ leads per month) who need to manage and assign territories to sales teams
  • Who need advanced automation capabilities like AI-powered email personalization and workflow automation
  • And/or who need integrated email engagement sequencing and tracking functionality

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

8/10

<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>

<p><span style="color: rgb(0, 0, 0);">Uplead's no-frills feature set means that its web app is relatively easy to navigate. Its prospecting interface is familiar when compared to competitors, however, some interfaces are clunky and cramped and often require a second look to find the data point/button you're hunting for. It would take an average SMB employee a few hours to master its use.</span></p>

Look and feel

7/10

<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>

Look and feel

2/10

<p><span style="color: rgb(0, 0, 0);">Uplead's design and UI feels dated. When tested, we find many pages to be overwhelming and confusingly laid out which made navigation difficult at times. Additionally, search pages were often slow to load (occasionally taking &gt;5 seconds to load).</span></p>
Customisability

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>

Customisability

4/10

<p><span style="color: rgb(0, 0, 0);">While Uplead offers the ability to create custom lists, it lacks some customisability facets that larger businesses may find helpful. These include the ability to save and share custom searches with colleagues or to manage and assign territories to specific sales agents.</span></p>
Ease of Setup

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

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>

Customer Support

8/10

<p>You can contact Uplead's support agents via a live chat widget in their web app. When tested, we find it quick and simple to contact a real support agent (often &lt;5 mins) and once contacted, we find them to be helpful and about to troubleshoot technical questions often in the first response.</p><p>Additionally, Uplead provides a help centre which should cover most basic support needs.</p>

Integratability

<p><span style="color: rgb(0, 0, 0);">Seamless.AI provides a number of integrations with popular CRMs (Salesforce, Hubspot), email engagement platforms (Salesloft, Outreach) and automation platforms like Zapier. However, we would like to have seen an API which could be leveraged to interact with their database directly - this is something which is offered by most competitors. </span></p>
