1. ListKit Sales Intelligence- The #1 Seamless.AI Alternative

G2 Rating: 4.9/5 (300+ reviews)

Watch a 1-minute demo from our co-founder Christian here:

Alright, we might be a little biased, but ListKit was built by 7-figure cold outreach pros with one mission: to make outbound campaigns insanely successful. Since launching in 2024, it’s become a go-to for B2B lead generation, offering Triple-Verified leads, a 626M+ contact database, advanced filters, and a credit-based pricing model—perfect for sales teams and agencies needing reliable, cost-effective data.

Some wins we’re proud of:

• Daavi scaled his coaching biz to $46k/month using ListKit’s Triple-Verified emails.
• JP & Pacs scored a $10k contract for their Klaviyo agency with ListKit’s lead data.
• Alex Heiden books 200 demo calls every month, thanks to ListKit’s verified emails and phone numbers.

Oh, and we scaled past $1.5M ARR in just 90 days using our own platform. No wonder we’ve got a 4.9 rating from 300+ glowing reviews!

Beyond lead verification and customer support, companies are increasingly turning to AI development services to supercharge their sales intelligence workflows.

By integrating custom AI models into platforms like ListKit, businesses can automate lead scoring, predict buyer intent more accurately, and detect patterns across massive datasets that human teams might miss. This not only sharpens targeting but also helps reduce wasted outreach, giving sales and marketing teams a competitive edge.

Here’s why:

‍

Key Features: What Makes ListKit Stand Out

• Triple-Verified database: Unlike Seamless.AI’s incorrect or outdated contact information, ListKit’s 626M+ contact database undergoes a Triple-Verification process, ensuring you only pay for confirmed, deliverable emails and phone numbers.

ListKit's lead verification

• Proactive customer support: While Seamless.AI struggles with response times, ListKit provides weekly coaching with 7-figure entrepreneurs and a vibrant community for actionable advice and real-time strategy sharing.
• Intuitive interface: ListKit provides an easy-to-use, glitch-free platform, avoiding the lags and technical issues users experience with Seamless.AI’s Chrome extension or bulk actions.
• Advanced intent tracking: Track prospect engagement and interest with customizable filters to target high-intent leads, ensuring your outreach aligns with real buyer behavior.
• Comprehensive market insights: Visualize your total addressable market with detailed pie charts, bar graphs, and maps, revealing industry breakdowns, key roles, geographic reach, company size, revenue, intent, and audience demographics like age and gender.

ListKit pricing

Offers a 7-day free trial with 50 included leads. Pricing starts at $97 for 2,000 Triple-Verified email credits and 100 phone number credits.

2. Cognism

G2 Rating: 4.6/5 (725 reviews)

Cognism

Cognism, founded in 2015, is a trusted sales intelligence platform for 3,000+ revenue teams. Targeted at sales, marketing, and revenue teams, Cognism's core features include GDPR-compliant contact data, advanced filtering, real-time enrichment, and exclusive mobile accuracy with Diamond Data®.

‍

Key features

• European-focused, GDPR-compliant database: Unlike Seamless.AI, Cognism excels in European markets, offering the most accurate, GDPR and CCPA-compliant contact data.
• Phone-verified mobile numbers: Cognism's phone verification provides 87% accuracy for mobile numbers, reducing wasted outreach efforts.
• DNC list filtering: Unlike Seamless.AI, which lacks DNC list filtering, Cognism cross-references data against DNC lists in 12 countries, ensuring legal compliance and better outreach success in global markets.

Considerations

• Limited customer support: Users mention slow and inefficient customer service, which sometimes requires lengthy email chains for simple issues.
• Limited export capabilities: Exporting leads can take time, as users can only copy a limited number of leads at a time.

Cognism pricing

Cognism's pricing details are not entirely transparent, but Vendr reports that annual contracts typically range from $15,100 to $103,000, with Platinum plans beginning at $1,500 and Diamond plans at $2,550.
