Seamless.ai

Seamless.AI's real-time search engine allows users to find verified B2B contact information including email addresses, direct dial phone numbers, and mobile numbers for decision-makers at target companies. Unlike traditional databases that rely on pre-collected data that becomes stale over time, Seamless.AI uses AI algorithms to search, verify, and validate contact information at the moment of request. Users can search by company name, job title, location, industry, company size, and other firmographic criteria. The platform's AI engine cross-references multiple data sources and applies proprietary verification algorithms to ensure the contact information is current and accurate. This real-time approach means users get the most up-to-date information available, significantly reducing bounce rates and improving connection rates for outreach campaigns. Eliminates wasted time on outdated contacts and increases email deliverability and phone connection rates by 3-4x compared to static databases.

The extension works seamlessly with LinkedIn Sales Navigator, enabling users to build targeted lists while conducting their normal LinkedIn research. The tool also works on company websites and other business directories, providing a consistent prospecting experience across the web.

Seamless.AI's data enrichment capabilities automatically fill in missing information for existing contacts in your CRM or prospect lists. Users can upload partial contact information or company names, and the AI engine will search for and append verified email addresses, phone numbers, job titles, company information, social media profiles, and other relevant data points. The enrichment process uses machine learning to match records with high confidence, reducing false positives while maximizing data completion rates. This feature is particularly valuable for cleaning up legacy databases, enriching inbound leads that only provided minimal information, or enhancing lists purchased from other sources. The platform can process bulk enrichment requests for thousands of contacts simultaneously, with results typically delivered within minutes. Transforms incomplete contact databases into actionable prospect lists, increasing the usable portion of existing databases by 60-80%.

Plans allocate a monthly credit pool (e.g., 10,000 credits for Pro) that is consumed per agent action, with optional extra vendor credits for higher‑capacity LLM usage. Credits reset monthly, and unused credits roll over on Enterprise plans. Aligns cost with actual usage, making the platform affordable for startups and predictable for large teams.

Seamless.ai

Seamless.AI provides buyer intent signals and job change alerts to help sales teams identify prospects who are most likely to be in-market for their solutions. The intent data feature tracks digital signals across the web to identify companies actively researching topics related to your products or services, scoring accounts based on their likelihood to purchase. Job change tracking monitors when contacts move to new companies or get promoted, creating warm outreach opportunities since professionals in new roles often have budget authority and are actively evaluating new vendors. Users can set up automated alerts for specific triggers, such as when a contact at a target account changes jobs or when companies in their ideal customer profile show buying intent. This intelligence helps sales teams prioritize outreach efforts and craft more relevant, timely messaging. Increases conversion rates by 2-3x by enabling sales teams to reach out at the optimal moment when prospects are most receptive.

The Autopilot feature automates the process of building and maintaining prospect lists based on predefined criteria. Users set up search parameters including industry, company size, location, job titles, technologies used, and other firmographic and technographic filters, and Seamless.AI's AI engine continuously searches for and adds new contacts that match those criteria. The system automatically verifies contact information before adding prospects to the list, ensuring quality remains high. Autopilot runs in the background, so users wake up to fresh, verified leads each day without manual searching. The feature also monitors existing contacts for changes, updating information when people change jobs or companies, and can automatically remove contacts that no longer meet the criteria. This ensures prospect lists remain current and relevant over time without ongoing manual maintenance. Eliminates manual prospecting work, saving 10-15 hours per week while ensuring a constant pipeline of fresh, qualified leads.
