A real-time search engine for B2B sales leads that helps you find everyone's contact information.
Final Score: 6.4/10. A genuinely massive database and real-time search technology, but the complete absence of published pricing and a mandatory annual contract make this a bet that needs real caution. If you are experimenting with new tools in your ai shortcut lab, the 50 free credits are a great starting point, but if you genuinely need a large volume of real-time B2B data and accept negotiating an annual contract, Seamless.AI is worth requesting a formal quote and comparing carefully.
Skip it if you want to know the price before talking to a salesperson. Every paid tier on the official pricing page says "Contact sales," with no dollar figure published anywhere, not even as a rough starting price.
Skip it if you want real month-to-month flexibility. Per Seamless.AI's own Terms of Use, all subscriptions are annual contracts; choosing "monthly billing" only changes your payment schedule, not the 12-month commitment itself.
Skip it if you're uncomfortable granting broad rights over data you connect. Seamless.AI's Terms give the company an irrevocable, perpetual, worldwide license to use, sell, and create derivative works from any data you submit by connecting your CRM or email accounts, without compensation.
Seamless.AI is a B2B prospecting tool offering a massive, real-time-searched contact database of over 1.8 billion emails and 414 million phone numbers. While it provides excellent data and built-in engagement tools, it completely lacks public pricing and locks users into mandatory annual contracts.
A Typical First Search, Step by Step
Compared to manually searching for contacts across scattered websites, the real-time search engine removes a genuinely repetitive burden of verification and assembly.
The Solo Founder Math: Because Seamless.AI publishes no price for any paid plan, a real ROI calculation isn't possible until you have an actual quote from sales. The free plan's 50 credits cost nothing, but they're only enough to test data quality on a small sample.
If you need a large, ongoing volume of contact data, the value of a massive, real-time-searched database is real, but it has to be weighed against a full annual contract whose true cost you won't know until you've negotiated it. For anyone who only needs a handful of contacts a month, an alternative tool that publishes its price directly likely offers more clarity.
Free ($0): 1 user, 50 credits. Includes email addresses, cell phones, real-time search engine, enterprise security, export downloads, and Pitch Intelligence. Does not include AI Assistant, Data Enrichment, Autopilot, or Buyer Intent Data.
Pro (Contact Sales): Priced "Per User" with no public figure. Unlimited exports, Annual Credit Packages. 1 credit covers both a phone number and an email. Pro plans start at a 10,000-credit annual minimum. Adds Connect (emailing, calling, tasks), Job Changes filter, and API access.
Enterprise (Contact Sales): Custom pricing. Unlimited users, custom packages, dedicated customer success manager. Data Enrichment, Autopilot, and Buyer Intent Data are included.
⚠️ Contract Warning: All subscriptions for the Services are annual with monthly or annual billing cycles. Choosing "monthly billing" does not give you a month-to-month cancelable plan. You must cancel at least 60 days before renewal or it auto-renews. Additionally, total liability is legally capped at just $100.
Signing up for Seamless.AI is free and requires no credit card for the starting 50 credits and 1 user. From the dashboard, you can search for a contact and get back an email and phone number using a search engine that crawls the web in real time.
The likely friction point isn't signing up, it's what comes right after. Once the 50 free credits run out, the only next step is contacting sales without knowing the price in advance, which is not a self-serve upgrade at a known rate.
A key gotcha: If you connect a CRM or email account to the platform, the Terms of Use grant Seamless.AI a broad license to use that connected data.
Seamless.AI's interface centers on a contact search screen, with a sidebar for your saved contacts. The Chrome extension extends the same search to work directly while you browse any website, finding professional data without leaving the page you're on.
An automation dashboard and a tasks view show outreach campaigns and their results in one place for anyone using Connect and Autopilot together. The platform is clearly oriented toward an active sales team, not an occasional individual researcher, meaning the depth of automation goes well beyond what's actually needed for simple searches.

The free plan gets a self-serve knowledge base, email support, and a live training webinar, with no live chat, no dedicated success manager, and no phone support. Pro adds a priority support queue and live chat support, but still no dedicated success manager or phone support.
Enterprise alone adds a dedicated customer success manager, quarterly business reviews, and phone support "available upon request." The unusually low liability cap ($100) in the Terms of Use is worth knowing as part of support reality; it defines what's legally recoverable if something goes seriously wrong.
Note: This review draws only on Seamless.AI's official pages, not third-party review sites.
Testimonials on the homepage from VPs of Sales and Enterprise Account Executives, plus "President's Club" success stories, show a clear focus on individual sales rep results inside larger teams, not solo founders specifically. The company also cites cumulative aggregate figures like over 2 billion leads researched and over $91 billion in revenue generated.
