Seamless (formally Seamless.AI) Reviews & Product Details

Seamless.ai (the B2B sales intelligence platform) consistently highlight its real-time search engine as its most powerful asset. Unlike static databases, the platform uses AI to crawl the web instantly, often uncovering verified emails and direct dials that competitors miss.

Sales teams value the Chrome Extension, which allows them to capture leads directly from LinkedIn or company websites and sync them to CRMs like Salesforce or HubSpot with one click. Additionally, users appreciate the "Autopilot" feature for automating list-building and the "Smart Lists" that provide fresh daily leads, significantly reducing manual research time and boosting overall prospecting efficiency.

While the lead generation is fast, the data accuracy can be a major headache. I’ve run into too many "verified" emails that ended up bouncing, which puts my domain reputation at risk. The user interface also feels a bit cluttered and overwhelming, making the learning curve steeper than it needs to be. Review collected by and hosted on G2.com.

I really like that Seamless gives lots of phone number options, more than one email, and multiple bits of data. Seamless offers many more phone numbers than other software, and they're updated regularly using AI in real time, making them feel more accurate. Review collected by and hosted on G2.com.

I really don't like the fact you have to hit "find" and then get it to load, but I understand why it does that because it's searching in real time. The thing I would definitely change though is having an employee scale rather than actual employee number, even if it's a bit of a guess. It makes it really, really hard because if you work for a company that's segmented in different employee numbers of who you can reach out to and who you can't, having 50 to 200 or 200 to 500 employees is really frustrating. if your cut off is 250 Review collected by and hosted on G2.com.

Seamless.ai is extremely powerful when it comes to quickly finding contact data and building prospect lists. The platform makes it very easy to discover potential leads, especially for outbound sales teams. I particularly like the speed of the search and the ability to enrich company and contact data in a few clicks. For sales prospecting and lead generation it can significantly accelerate workflow compared to manual research.

The interface is fairly straightforward and once you understand the filters, you can build very targeted lists. The integrations with CRM systems and sales tools also help streamline the process of moving leads into sales pipelines. Review collected by and hosted on G2.com.

The data quality can be inconsistent at times. Some email addresses or phone numbers need additional verification, so it’s important not to rely on the data blindly. I’ve also run into occasional bugs or UI glitches, especially when exporting lists or running larger searches.

Customer support can be slow depending on the issue, and the pricing structure can feel expensive for a small team if you don’t fully use the credits. Review collected by and hosted on G2.com.

The only redeeming quality of Seamless.AI was its integration with Salesforce — that part worked. Unfortunately, much of the contact data populated into our CRM was inaccurate, which ultimately defeated the purpose. Review collected by and hosted on G2.com.

Terrible customer service experience. I reached out multiple times to discuss amending my contract due to changes in our systems — a completely reasonable request — and was met with complete silence. No response to emails, no response through the help desk. They simply ghosted me.

What's most frustrating is that I wasn't asking for anything unreasonable. I just wanted the opportunity to explain my situation and work together toward a solution. They wouldn't even give me that. Zero communication, zero flexibility, zero accountability.

The product may work for some, but if you ever run into a contract or account issue, don't expect any support. I would not use Seamless.AI again and would not recommend them to anyone who values responsive, professional customer service. Review collected by and hosted on G2.com.

The price/benefits ratio is pricely were a contact search tool should be located. And the tool finds about 90% contacts correctly that we need to look up. A clean user interface, allows you to quickly find not only your curent information, but also look up you past searches.

The export tool is great whcih creates you a file that can be operated in Excel.

This tool has all the needed features to satisfy our needs. Review collected by and hosted on G2.com.

Sometimes it doesn't find a contact, or only after I also put the company information in. I don't like to do this, becasue in rare cases this tool makes up an email address. I use this feature as the last resort.

I also dind't find yet an ability to give my feedback and it stays in the record when I found a functional email address.

Lastly at the begin of a search I would like to select the category where the contact should be automatically store. Right now I can only do this after it finds the contact and I change a from default association to my select. of course I could change the default, but then I have to do this probably on every second search.

What stands out the most about Seamless (formally Seamless.AI) for me is the real-time data verification. Unlike other databases that can have outdated contact information, Seamless AI researches and verifies data in real-time. This significantly improves deliverability and reduces bounce rates in our outbound campaigns. This feature is quite unique compared to other service providers. For early-stage founders, who often run lean and can't afford to waste resources on failed outbound attempts, this is invaluable. Review collected by and hosted on G2.com.

I think that Seamless works pretty well, so there's not a big opportunity for improvement. That said, one of the main areas for improvement is data accuracy consistency. While the real-time verification is a strong feature, the quality of the contact data can vary depending on the industry and seniority level of the prospects. For instance, direct dials, in particular, tend to be hit or miss, especially for senior decision-makers who are harder to reach. Review collected by and hosted on G2.com.

I find Seamless (formally Seamless.AI) very easy to use. I love the ability to filter as finitely as I want to dig in deeper and be very specific, or to keep my searches more broad. The filtering options are great because I can find a very specific industry or job position, and also target specific areas, allowing for very finite searches. It also allows me to keep my search more broad to maybe cast a larger net of prospects. Additionally, the initial setup was super easy and very quick to do. Review collected by and hosted on G2.com.

I would like to see the CRM integration to go high level via native CRM integration, and I think the different levels of cost could be more cost competitive. Review collected by and hosted on G2.com.

What I like most about Seamless.AI is how accurate and comprehensive the contact data is, especially when it comes to identifying decision-makers and qualified leads. After more than two years working with the platform across different companies, I’ve seen firsthand how powerful it is for both prospecting and enriching our existing database. The integration with outreach workflows is smooth, and the tool helps accelerate the entire lead generation process in a way that is difficult to achieve with other platforms.

At times, some contact information may need validation, especially in less active markets, which requires occasional manual double-checking. However, even in those cases, the volume and ease of access to data still make the platform highly efficient and worth using daily. Review collected by and hosted on G2.com.
