“The best tool for prospecting, does a lot more than contact info. | If you need to build prospecting lists and then fill them with contacts and contact info, this is the best tool I've used in 20+ years. If you know how to use it, it is the only sourcing and contact info tool you need. I don't know what scenarios it isn't important for because all I do is sales with a ton of prospecting. | Pros: Correct contact info. | Pros: Easy to use UI with powerful search abilities. | Pros: Amazing custome”

NEGATIVE trustpilot

“Yeah, 1000 leads sounds great until you realize the majority of the "enriched" leads dont' have working emails or phone numbers. They lock you in for 12 months with no break clause and send you to collections. Offered even half up front as a buy out. Scammers. ”

NEGATIVE trustpilot

“Do not use this service. Over 15 years in marketing and lead gen, this is the most predatory company I have ever seen. Run, don't walk, away from this software. Submitting to BBB and others now. You will never get out of the contract and the leads are very poor compared to others (ran multiple side by side studies). ”

NEGATIVE trustpilot

“Predatory and low-value. Not only to the have the guts to try and muscle you into additional yearly contracts through deception, ghosting, and threats; but they also offer a garbage service that doesn't deliver anywhere close to the results promised. Their AI is trash and doesn't gather actionable information- you're genuinely better off Googling. Customer service is abysmal, inconsistent, and straight up rude. Give your money to literally anyone else.”

“It's by far the best solution out there for the price - It's about 10-15% of Zoominfo.”

“If I ever needed a lead gen platform again, I'd stay away from Seamless. Declining another year of Seamless.AI shouldn’t require an appointment. But their portal puts a mandatory meeting between me and submitting a nonrenewal request, with limited slots that don’t work for my schedule. That feels designed to wear customers down rather than respect their decision. I’m simply asking them to disable auto-renewal and confirm it in writing.”

“Seamless.AI - Agility in your Lead Capture. | Seamless AI is very well suited for the first round of prospecting, or when going after a very publicly known and traded company. A good example would be popular brand names in the country. Whereas it does show limitations for smaller companies, it cannot yield deep data in the same way as others might. However, it is agile, very fast, and compatible. I highly recommend it to any sales force. | Pros: Lead capture, and management. | Pros: operates ver”

“One of the worst companies we have dealt with in terms of customer service and platform reliability. We worked with Autumn Kunce, a Customer Success Manager, whose focus remained on enforcing payment rather than resolving the ongoing access and service issues. Neither she nor the broader team was able to provide a workable solution, despite us having paid for a full year of a platform we were ultimately unable to use.”

“This business is a scam. If you’re considering purchasing licenses from them, don’t. Their platform doesn’t work properly, the umbrellas are old, and 95% of them are useless. When you try to get support, they claim to be working on fixing it but never launch any fixes. It’s a terrible experience. ”

“Terrible. We used it for two years. Year one was pretty good. This year the bounce rates are %18-%23 and the system (extension and data gathering tools) has broken several times. They provided a free use of AutoPilot for the inconveinence, but those emails just bounce. This is a business in BIG TROUBLE. Without good data they are dead in the water. Dont buy it. There are far better tools out there. PS: Their list downloads say "cleaned," and if you run them through a email data cleaning servic”

“IMO I would hold off for ZI. I’ve used both Seamless and Zoom Info, and can definitely tell you ZI is a significantly better product, with great support. They’re a well put together company. I’m sure as a rep you’d get a ton of inbound (not sure about this, but assuming) and if you do outbound, you’ll have the brand recognition on your side. Plus it’ll look great on a resume moving forward. Good luck!”

“Worst experience dealing with a company I ever had. Started off with aggressive sales people promising the works to get you to sign a contract designed to trap you. After you sign up no one follows through until you try tk cancel when they start throwing around the contract that they never fulfilled in the first place. Avoid using this company at all cost spare yourself the wasted time, money and aggravation I am sure they will probably find a way to make me writing a negative review a breach of”

“Can't imagine going back to manual prospecting after using this. Haha! its like thinking back to the days we used to keep maps in our cars before GPS! I suspect sales reps will never know about all the time we spent going through websites and out of touch databases.”

“I signed up for a Seamless.AI annual subscription for my business. When I decided not to renew, I discovered there was no simple way to cancel online. The company automatically charged my card $2,200 without any advance notice or renewal warning — something both the FTC and Illinois law require. To cancel, Seamless.AI forces you to book a meeting with a sales rep, which is inconvenient and feels like a tactic to pressure customers into staying. I didn’t want the service anymore and shouldn’t ha”

“New user. They only offer B2B Intent and cold information. After you build your intent list (businesses) no direct person to contact, then you can upload contacts based on titles you want to contact. But the bad thing is if you have 15 companies and say 150 employee contacts you will need to click on Name to select all on one page not the entire list then save, one page of 50 at a time. Not the entire list. So if you have 5 pages of 50 names on each page then your saving each page one by one no”

A composite of the quality dimensions weighted by mention volume, then capped by predator / abuse-detection rules.

Reasoning

predation flagged: k=51/n=109 (raw 47%, clean mass discounted ×0.5 [star_bimodality,incentivized_reviews] → n_eff 80.0), posterior 0.578 + tripwire (51 predatory across 5 sources), tier=dark_pattern → trust 19

Reviewers report billing concerns

Multiple reviewers report difficulty canceling subscriptions, with the company requiring 60-day written notice and forcing customers to schedule sales calls to cancel.
