"Great Tool but Dishonest Company"
What do you like best about Seamless.AI?

Seamless makes it very simple to locate potential contacts and their contact information

What do you dislike about Seamless.AI?

They send an abundance of spam emails that you need to unsubscribe from. Additionally, they paid for these reviews via Gift Cards but underpaid what they originally stated. Dishonesty is not something I can support.

What problems is Seamless.AI solving and how is that benefiting you?

Very few problems. Benefits include ease of use, quick results, and above all reliable results

What do you like best about Seamless.AI?

I like the integration into Hubspot the best,

What do you dislike about Seamless.AI?

It is not accurate and has only a fraction of the relevant contacts I search for.

What problems is Seamless.AI solving and how is that benefiting you?

Inaccurate contacts, wrong emails, not sync'd data. Of the minimal contacts that I have found, only a handful are up to date.

"Good availability of names, fast, easy to use, a few headaches"
What do you like best about Seamless.AI?

Seamless has a great list of available names. it's fast, easy to use, and its search function works well.

What do you dislike about Seamless.AI?

The contact information is guessed by their AI, sometimes it's very accurate, and other times it's not.

What problems is Seamless.AI solving and how is that benefiting you?

I've found literally hundreds of prospects and potential candidates.

"Mixed Results"
What do you like best about Seamless.AI?

I like that it does have plugins and integrations that make it easy to pull contacts from websites.

What do you dislike about Seamless.AI?

A bunch: 1. Email Data. Since purchasing, we've seen around 20% of emails bounce back because they weren't correct. 2. Technology. We specifically purchased Seamless to find companies with certain technology, but half the time that information is out of date compared to Wappalyzer 3. Upsells. Seamless.ai literally charges you for auto clicking a button. It's the most insane thing ever and then we get constant upsells for additional features. I'm not sure once anyone has contacted me to ask how I like the product.

What problems is Seamless.AI solving and how is that benefiting you?

It is helping me find buyers, but the most critical issue is that the data is inaccurate or incorrect.

"It's helpful, but not perfect"
What do you like best about Seamless.AI?

It's great at providing targeted contact information

What do you dislike about Seamless.AI?

The information pulled is not always accurate or current. For example, we've pulled contact information for people who it turns out don't work at that company anymore and haven't for some time - even though we filtered that way.

What problems is Seamless.AI solving and how is that benefiting you?

We need new leads and contacts

"Be careful what you're buying"
What do you like best about Seamless.AI?

The account manager was very helpful while deciding which platform to go with. He was patient and hopped on a few calls to answer my questions. The tool allows for 1,000 contact downloads a day, which is more than most other platforms.

What do you dislike about Seamless.AI?

They claim to have the most data, but they are missing A LOT of data (for example, out of 600,000 restaurants in the USA, they had less than 2% on Seamless). Also, they claim data comes from Linkedin, but it's definitely not as it doesn't list all employees of a company - companies we work with have over 500 employees, and Seamless often only shows 2 or 3! There are also a lot of unresolved bugs that the company and team (client success, AM, support) don't care about fixing. For example, even if you select a specific department to find contacts of a company, it will list a bunch of other unrelated roles from other departments. Also, you can't download a list at once, you have to do it page by page (and pages only contain 15 results!) So even if you're allowed to download 1,000 contacts a day, it takes forever!

What problems is Seamless.AI solving and how is that benefiting you?

We use Seamless to find key decision makers and their contact information. Since the process has shown a lot more difficult and tidious than expected, we unfortunately do not see benefits as it is now.

"Seems like a good idea, execution is poor"
What do you like best about Seamless.AI?

It's a plugin to find employee and leadership info on a website. Also, the Sales Navigator plugin allows you to scrape and transfer leads over to Seamless lists.

What do you dislike about Seamless.AI?

The data scraper will routinely bring up bogus or previous emails. Sometimes, it would even fabricate emails based on the pattern companies used as a naming convention for emails. You would build up a massive list just to get a 20%-30% bounce rate.

What problems is Seamless.AI solving and how is that benefiting you?

Initially, it helped us with cold outreach. Email and cold calling. It allowed us to be productive while we worked up our organic and paid strategies, as well as our partnerships and referrals.

"Looking for something cheaper than ZI and found it...and I understand why it's cheaper"
What do you like best about Seamless.AI?

1. 1,000 searches/downloads a day 2. The phone numbers seem to be accurate, when they are there - which is different than ZI.

What do you dislike about Seamless.AI?

1. The interface is cumbersome. 2. Would like a way to store all downloads in corporate account to avoid duplicates. 3. Can only see 10 companies at a time. 4. Very tedious to add data. 5. The email addresses are not great! So many bounce and they really boast how thorough their review process is in checking data. 6. Support hasn't been great. They've gone silent since we we live, which is quite the turn. The sales process had an Account Manager/Executive reaching out daily.

What problems is Seamless.AI solving and how is that benefiting you?

We wanted a source of data that wasn't close to $30k, which is what we were paying ZI and Seamless fit the bill. It hasn't increased productivity because the tool is cumbersome to use.

"Good Software but Poor Customer Support and Won't Cancel Subscription at end of Year"
What do you like best about Seamless.AI?

The software performs as expected and delivers ease of use and good information

What do you dislike about Seamless.AI?

They will do everything they can to not cancel a subscription and will keep charging after cancelation. Really tough to end the service. Shame to have a good product but lack integrity when it is time to part ways.

"Mediocre solution at best"
What do you like best about Seamless.AI?

cost is cheap so if you are on a budget, this can be a valid solution for list building. I do like how it has a browser extension and works within linkedin.

What do you dislike about Seamless.AI?

Quality of emails is terrible, constantly having to use Lusha to supplement email finding. It is super slow to load most of the time. Phone numbers are correct maybe 2 percent of the time. Segmentation of industry and sub industries are challenging. For example, I have a tough time finding lighting manufacturers without pulling in a ton of energy companies. Also cannot pull interior designers vs. graphic designers or branding agencies. For some reason, I get a lot of toy companies in my lists when my main target are architecture and design industry companies. Email quality is poor - Kickbox usually verifies only 15% of the emails taken from seamless. With Seamless and needing to use supplemental software, building a list of 600 people takes me about 6 hours....

What problems is Seamless.AI solving and how is that benefiting you?

list building - i am able to build b2b lists but the time it takes to accomplish the task is bogging me down.

"Not as good as ZoomInfo, but a lot cheaper"
What do you like best about Seamless.AI?

The cost. I think we're paying about $6K for an annual subscription. Probably 1/3 of what ZoomInfo would cost.

What do you dislike about Seamless.AI?

1. Limited searchability. There are only a few fields you can use to search, and some of these have a limited number of options. (For title searches for example, you can only do a total of 7-8 positive and negative keywords.) 2. Wonky overall. It consistently returns contacts that don't meet the criteria I'm searching for. 3. Manual effort - a lot of work to select all of the contacts that you want to save, download, etc. They have a HubSpot integration, but you have to click the HubSpot icon on EACH contact. So if you want 100 contacts, that's 100 clicks (plus additional clicks to get to advance the pages.)

What problems is Seamless.AI solving and how is that benefiting you?

We essentially built our contact database from scratch. So Seamless was a good, affordable way to find a lot of relevant prospects.

What do you dislike about Seamless.AI?

"Bad customer service, causing it to be not value for money"
What do you like best about Seamless.AI?

the tool itself is affordable for SMBs, and the data itself we can say is 60-70% accurate (from a bounce rate perspective).

What do you dislike about Seamless.AI?

Their customer support/service is one of the worst I've encountered. isn't worthing the cheaper pricing you pay vs. the industry-standard solutions, as it costs you with the time you need to invest in fixing settings problem, or with understanding why and to solve the below: - users are losing access to the platform - billing issues - changes with CSM without any notice - no replying to emails the thing is, we extended our contract after the first year (although all the things I wrote above happened), but now, after the second year of the contract has gone, we won't continue with seamless.ai as the history repeat itself and even a worse shape than last year

What do you dislike about Seamless.AI?

The seamless navigator is horrible. If you don't have linkedin sales nav then seamless is basically useless. Also, Many leads simply won't import and have no explanation. Then, many leads, sometimes 20-30% of an import will have wrong names and contact info.

"Not a great product. Not even worth the $150 a month expense. They do offer great service"
What do you like best about Seamless.AI?

Their customer service team is very responsive if a question arises. They provided adequate follow-up, and they do care about listening to any issues.

What do you dislike about Seamless.AI?

The contact information isn't great. There is a high bounce rate for emails. Many phone numbers are just the primary number you could find on the company's insight. When you search for companies in a particular industry, you don't get many results. The AE that worked with me didn't provide a great experience, and they didn't ask too many provoking questions as to why I was interested in using the platform. I had a couple of questions after I purchased, to which the AE said they would talk to their engineering team and get back to me. The AE never responded. Not even worth spending the $150 a month for the subscription.

"Alright Platform - Not the greatest support team"
What do you like best about Seamless.AI?

It served its purpose of searching for contacts number, email and relevant information.

What do you dislike about Seamless.AI?

The sales and support team was not supportive during the COVID era and consistently threw legal jargon to reinforce their point. Was not willing to be flexible and offer alternatives. The data that was provided could not be altered in a way with HubSpot that properly allows automation and quality check before loaded into HubSpot. There was no forum for product enhancements. We did not receive an onboarding - nor did we have anyone introduce themselves as support post-sale. Kinda left on our own. They had an odd clause that if you failed to notice before 60 days of desire to cancel, they would automatically re-enroll you onto another annual contract.

What problems is Seamless.AI solving and how is that benefiting you?

We needed leads and prospects to engage with accuracy. Seamless filled the void compared to the competitor ZoomInfo who we were comparing with. Massive price difference but clear indicators of added features and support. We got our leads with 80% accuracy which was good to know

"Accurate and Quick"
What do you like best about Seamless.AI?

Accurate information, Can get more credits by referring team members or coworkers and even by completing the tutorials!

What do you dislike about Seamless.AI?

I wish you could search by address. I prospect based off of corporate address, location is key for me. I also would like to narrow down my Contact search with more filters. There are more on the Company search, but you cannot filter by State.

What problems is Seamless.AI solving and how is that benefiting you?

When I cannot find the phone or email to the person I need, I use Seamless to find it. The phone number is usually a general company line, but not always! The email is typically accurate, more accurate than other .AI companies I also use.
