Seamless.AI is a real-time B2B search engine and contact database designed to help sales and marketing teams find verified prospect information at scale. With over 1.7 billion contacts and 150 million company profiles, the platform uses artificial intelligence to crawl, verify, and validate contact data in real time, providing direct dials, mobile numbers, and email addresses for B2B outreach.
What is Seamless.AI?
Seamless.AI positions itself as the “#1 rated sales lead AI software” for B2B prospecting. Unlike static databases that quickly become outdated, Seamless.AI continuously validates contact information through multiple data points and AI-powered verification processes. The platform enables sales teams to build targeted prospect lists, enrich existing CRM data, and identify high-intent buyers through behavioral signals.
The core value proposition centers on data accuracy and freshness. Rather than purchasing fixed contact lists, users access a living database that updates in real time, theoretically reducing bounce rates and improving connect rates for cold outreach campaigns.
Key Features
AI-Powered Prospector The Prospector tool functions as an advanced lead search engine with granular filtering options. Users can search by industry, job title, location, company size, revenue, technologies used, and custom keywords. Results include verified emails, direct dial phone numbers, mobile numbers, and detailed company information. The AI algorithms work to surface the most accurate contact details by cross-referencing multiple data sources.
Data Enrichment Seamless.AI’s enrichment capabilities transform incomplete contact records into full profiles. Users can upload CSV files with partial information—such as email addresses, domains, or phone numbers—and the platform fills in missing fields. The Chrome extension enables one-click enrichment directly from LinkedIn profiles, automatically pulling verified contact details into your CRM or export list.
Buyer Intent Data The platform monitors over 12,000 intent signals across the web to identify prospects actively researching solutions. Intent data helps sales teams prioritize accounts showing buying behavior, such as visiting competitor websites, downloading relevant content, or searching for specific product categories. This feature aims to reduce cold prospecting waste by focusing efforts on warm opportunities.
Job Change Tracking Seamless.AI automatically tracks when contacts change positions or companies, a critical signal for sales teams. When a champion moves to a new organization, they often need to purchase the same solutions again. The platform alerts users to these transitions, enabling timely outreach during the honeymoon period when new hires have budget authority and purchasing momentum.
AI Writer The generative AI writing tool creates personalized email copy, social messages, and outreach sequences based on prospect data. Users input key details about their offering and target audience, and the AI Writer generates contextually relevant messaging. While this accelerates content creation, the quality and personalization depth varies—most teams still need to review and customize the output.
Chrome Extension The browser extension integrates Seamless.AI directly into LinkedIn, enabling users to capture verified contact information while browsing profiles, company pages, or Sales Navigator search results. The extension shows email addresses, phone numbers, and an accuracy confidence score without leaving LinkedIn. Contacts can be added to lists or pushed directly to integrated CRMs with one click.
CRM Integrations Seamless.AI connects with major CRMs including Salesforce, HubSpot, Pipedrive, and outreach platforms like Salesloft and Outreach.io. The integrations enable automatic data sync, so enriched contacts flow directly into your existing workflows without manual exports and imports. API access allows technical teams to build custom integrations for specialized use cases.
Pricing Structure
Seamless.AI uses a credit-based pricing model where each contact export consumes credits. Pricing is not publicly listed for most plans, requiring prospective customers to contact sales for quotes. Based on third-party sources and user reports, here’s what the pricing landscape looks like:
Free Plan: Offers 50 lifetime credits (not renewable) to test the platform. Once exhausted, users must upgrade to a paid plan. The free tier includes basic search functionality and the Chrome extension.
Basic Plan: Starts at approximately $147 per month for individual users, refreshing 250 credits monthly. Some sources indicate pricing ranges from $79-$149 per user depending on negotiated terms and commitment length.
Pro Plan: Reported at $99 per user per month with a minimum of 5 users, though other sources suggest actual costs closer to $299 per user per month. The Pro tier provides daily credit refresh (approximately 1,000 credits daily), Pitch Intelligence, buyer intent data, and job change tracking.
Enterprise Plan: Custom pricing based on team size, usage volume, and required features. Enterprise customers receive dedicated account management, advanced integrations, higher credit allocations, and priority support.
Annual contracts are standard, with total costs ranging from $13,000 per year for small teams to $91,000+ annually for larger organizations. Add-on features like Autopilot, enhanced buyer intent, and advanced enrichment increase costs beyond base subscription pricing.
The opaque pricing model is a common complaint—72% of reviewers express dissatisfaction with pricing transparency and value for money. Prospective buyers should budget extra time for sales negotiations and plan for costs higher than initial quotes suggest.
User Experience and Reviews
Seamless.AI receives mixed reviews across platforms. On G2 and Capterra, the platform maintains a rating around 4.3 stars from hundreds of reviews, indicating moderate satisfaction with significant variance in user experiences.
Positive Feedback: Users praise the intuitive interface, large database size, and real-time verification. Sales teams appreciate the daily credit refresh on Pro plans, which supports high-volume prospecting activities. The Chrome extension receives particular acclaim for seamless LinkedIn integration. Many reviewers report that Seamless.AI delivers more accurate mobile numbers compared to competitors, improving cold calling connect rates.
Negative Feedback: Data accuracy concerns dominate critical reviews. Users report email bounce rates of 20-30%, with frequent job title mismatches and outdated information. While the platform claims real-time verification, many contacts fail basic validation when actually used in outreach campaigns. Reviewers also cite aggressive sales tactics, difficult cancellation processes, and threats when attempting to end contracts. The pricing opacity and perceived poor value for money (given accuracy issues) are recurring themes.
Overall, about 81% of reviewers feel positive about lead generation capabilities, but user satisfaction drops significantly when considering pricing and customer service experiences.
Ideal Use Cases
Seamless.AI works best for:
- Outbound sales teams needing high-volume contact data for cold email and calling campaigns
- Account-based marketing teams building targeted prospect lists by company and role
- Recruiting firms searching for candidate contact information at scale
- Partnership teams identifying decision-makers at potential partner organizations
- Sales operations enriching incomplete CRM records with verified contact details
The platform is less suitable for companies prioritizing data accuracy over volume, teams with limited budgets, or organizations uncomfortable with opaque pricing. Smaller teams may find the minimum user requirements and annual contracts restrictive.
Alternatives to Consider
Before committing to Seamless.AI, evaluate these alternatives:
- Apollo.io: More transparent pricing with a generous free tier, strong integration ecosystem, and engagement tools beyond data
- ZoomInfo: Premium option with higher accuracy rates, better intent data, and comprehensive company intelligence
- Lusha: More affordable for smaller teams, Chrome extension focused, with per-contact pricing options
- Cognism: Strong European data coverage with better GDPR compliance and phone-verified mobile numbers
- LeadIQ: Sales-first UX with prospecting workflows, email verification, and CRM enrichment at lower price points
Each alternative offers different tradeoffs in database size, accuracy, pricing transparency, and feature depth. Teams should test multiple platforms during free trials before making annual commitments.
Bottom Line
Seamless.AI delivers substantial value as a prospecting and data enrichment platform for teams that need volume at scale. The 1.7 billion contact database, real-time verification, and powerful AI search tools provide a strong foundation for outbound sales programs. Daily credit refresh on Pro plans and seamless CRM integrations support high-velocity prospecting workflows.
However, data accuracy concerns, opaque pricing, and customer service issues create significant friction. Email bounce rates of 20-30% undermine the platform’s real-time verification claims, and the difficult sales and cancellation process leaves many users frustrated. The 72% dissatisfaction rate on value for money suggests the pricing doesn’t align with delivered quality for a majority of customers.
For teams that prioritize finding new contacts quickly and can tolerate moderate accuracy issues, Seamless.AI deserves consideration. But organizations requiring high-fidelity data, transparent pricing, or strong customer support should thoroughly test the platform and compare alternatives before committing to annual contracts.
