Why

Why Are People Switching From Seamless.AI to Outbound System

Seamless.AI sells credits on quote-based plans. Teams choose Unlimited B2B Data for flat, published pricing and unlimited exports.

Published Pricing

Seamless.AI's pricing page is a form that asks for your monthly contact volume and company size before you see a number. Our plans are published: $199, $499, or $999 a month for Unlimited B2B Data. You can compare all three on the site, and the only differences are search speed and the number of team seats included.

No Credits at All

Credits are the unit Seamless.AI sells, and it refunds a credit when an email turns out to be invalid. Unlimited B2B Data has no credits at all, so there is nothing to refund, ration, or track. Every search and export is unlimited on every plan, and your team never has to budget leads against a balance.

Mobile Numbers Included

Mobile numbers come with every Unlimited B2B Data plan. The database includes 53M+ mobile numbers and direct dials, and they export alongside emails with no extra credits or phone add-on. Your callers get complete records in the same file, and building a larger calling list never changes what you pay Outbound System.

Build Full Lists

Search 390M+ contacts with 100+ filters and buying signals, using boolean logic or plain English, then export as many as you need in one pass. Starter builds a 50,000-lead list in about 5 minutes, and Scale does it in about 12 seconds. Each contact carries up to 165 data fields, so your list arrives enriched and ready to use.

Works With Your AI Assistant

Your AI assistant can build lists directly. API, dashboard, and MCP access are included on every plan, so Claude, ChatGPT, Cursor, or your own agents can ask for a list in plain English and get contacts back from 390M+ records. There is no extra license for API access and no credit charged per contact on Unlimited B2B Data.

Month-to-Month, Cancel Anytime

Contract terms on Seamless.AI are not published, so you learn them in the quote. Unlimited B2B Data runs month to month with no minimum term, and you can cancel from your dashboard in seconds. Before you pay, pull 5,000 fully enriched leads free with no card required and see what Outbound System covers in your market.

What to Ask in a Seamless.AI Quote

Seamless.AI prices by quote and credits, so ask three things first. How many credits do you get a month, and do unused ones expire? Is it billed per seat, and on what term? Are job changes, buyer intent, and enrichment extra? Unlimited B2B Data answers all three up front, with unlimited exports and 3 to 25 seats from $199 a month.

Want Us to Run the Outreach Too?

With Seamless.AI, your reps still prospect and run outreach themselves. Our done-for-you service takes that work off your team. Our people build the list, set up inboxes and domains, write the copy, manage deliverability, and run cold email, AI cold calling, and LinkedIn for you, from $1,499 a month, with a dedicated account manager.

You Want a Price Without a Quote

You Don't Want to Ration Credits

On a credit plan, each export is a decision about whether a contact is worth spending on. Every search and export on Unlimited B2B Data is unlimited, on every plan. Your team can pull a full market, re-run searches as targeting changes, and test new segments without watching a balance or waiting for a refill.

You Buy Lists Every Month

If you pull fresh lists every month, credits turn into a recurring tax on prospecting. With Unlimited B2B Data, the next list costs nothing extra. Build a new segment each month, refresh old ones, and re-export after your targeting changes, all inside the same flat plan from $199 a month with no top-ups to buy.

Phone outreach needs a number on every record, not just a few. Unlimited B2B Data includes 53M+ mobile numbers and direct dials in every plan, exported alongside emails at no extra cost. Your callers get full lists from the first search, and adding phone numbers never pushes you into a bigger plan or a credit refill.

"Because of the processes that Outbound System has developed and put into place, we have been fortunate to have cashflow of multiple six figures per year now. It's been a real game changer type of a gain that we've been fortunate to experience."

Monil Shah

Managing Partner at Tortoise Finance

"Before Outbound System, our deliverability was broken. We weren't landing in inboxes and were losing pipeline across all 35 markets we operate in. Within two weeks of onboarding, we were seeing significantly better results. Since joining, we've generated over 95 leads and built a pipeline that keeps converting months down the road."

Andrew Luedtke

Founder & Managing Partner at AVID Media

"For our business, landing even just one new client per month made this a worthwhile investment. We were easily engaging with 10+ high-intent leads each month (which in the marketing space, is very difficult to do with ice cold leads). I would heavily recommend Outbound and their team."

Will Laub

Co-Owner at Maverick Strategies

"I enjoy working with you personally and the team I have met so far! I think a lot of the value here is the collective wisdom of the Outbound System team to advise and optimize the campaigns. That’s premium is worth is weight in gold."

Derek Merrill

CEO & Founder at Vigur

"Over a year in and we've put up 120+ qualified leads, several of which have turned into long-term association partners. The thing I appreciate most is that Brandon hasn't changed since day one, same guy, same level of care, every single month. Honestly the lowest-maintenance vendor relationship I have right now and one of the highest-ROI."

Tyler Gilham

Sales Director at Lead Marvels

"Outbound Systems' onboarding and ongoing support is great. They were truly thought partners while creating our campaign, and the user interface is sleek. We've generated around 70 meetings so far and have cut down on our time spent messaging significantly"

Ace McGill

CEO & Founder at Value Buddy

"I'm actually extremely impressed with the results so far. It's only been a month into the cold email service with Outbound System, and we've already generated 36 leads in a notoriously difficult market (targeting medical practices). Keep it coming!!"

Randy Young

CEO at Med Profit Lab

"Before Outbound System, we were only getting 3-10 inconsistent leads per month through networking and referrals. In just one month with Outbound System, we've generated about 20 interested responses, booked 15 meetings, and closed 2 new clients. As I always say, doing LinkedIn outreach by yourself is only valuable if your time has no value!"

Clifton Jackson

CEO at FireVibe Web Design

"10 qualified conversations in 6 weeks, targeting is dialed in and we're refining our sales process and offer based on our learnings from Outbound System. So far so good!"

Michael Jaskulsky

Director of Business Development at UnDigital

"Outbound System has been great! I'd highly recommend their LinkedIn lead gen service. We ran 3 profiles with them, and we consistently generated at least 20 positive responses every single month in our local market. So very happy with the team. Great job guys!"

Melanie Shores

Director of Marketing at Modern Mingle

"The results that I got in the first month were WAY higher than the expectation set on the original sales call. I got 64 leads in less than 30 days. I had to pause the system for a while to work the pipeline. Brandon and the rest of the team at Outbound System really have something special here, and I'm speechless..."

Michael Larkin

Founder & President at SC Media Partners

"After getting burned by our previous lead gen provider, Outbound System actually delivered results. Their personalized approach worked when nothing else did. Worth every penny and would recommend to anyone tired of empty promises!"
