AI-Powered Lead Discovery and Qualification

Glasa employs intelligent AI agents that allow users to find, qualify, and book dream clients in minutes. Users can simply describe their ideal prospect using natural language, specifying criteria such as industry, job title, company size, and geography. The AI agents then browse the database of over 800 million pre-validated contacts, automatically narrowing down results and qualifying leads based on the specified parameters. This eliminates hours of manual research and ensures sales teams focus only on the most promising opportunities.

Triple Verified Contact Data Quality

Every contact in Glasa undergoes a rigorous three-layer verification process before it reaches your pipeline. The system performs format checks, domain verification against live mail servers, and real person confirmation to guarantee accuracy. With AI agents scanning over 35 live data sources in real time, there are no stale or outdated records. This commitment to data quality results in 95% title accuracy, 99% email accuracy, and less than 2% bounce rates, ensuring your team never wastes time or credits on bad data.

Comprehensive Inbox Warmup and Outreach Infrastructure

Glasa provides a complete solution for warming inboxes and managing outreach campaigns within a single platform. Users can choose their sending infrastructure from Google Workspace, Microsoft Outlook, or SMTP, and even mix providers within the same campaign. The platform includes an inbox marketplace where users can buy standard and warmed inboxes from trusted providers. AI agents automatically warm inboxes, run sequences, and manage every reply in a unified G-style inbox, where AI automatically categorizes leads by interest level and flags hot prospects.

REST APIs for Seamless Integration

For teams with existing workflows, Glasa offers full REST API access for both email verification and contact finding. Developers can plug email verification and contact finder functionality directly into their own stack using simple API calls. The verification API returns detailed results including validity and deliverability status, while the finder API enables automated contact discovery. This feature is built for high-volume pipelines and allows organizations to integrate Glasa's powerful data quality capabilities into their custom applications and CRM systems.

Targeted B2B Prospecting for Sales Teams

Sales teams can use Glasa to instantly find and connect with decision-makers at specific companies. For example, a sales representative looking for CTOs at B2B SaaS companies with 50 to 500 employees based in the US can simply describe this requirement to the AI agent. The platform automatically filters through 800 million contacts, validates each lead, and provides verified email addresses and direct dial numbers. This dramatically reduces the time spent on manual research and allows sales professionals to focus on high-value conversations with qualified prospects.

Marketing Audience Segmentation and Personalization

Marketing teams leverage Glasa to build highly targeted audiences for campaigns by filtering on job title, revenue, headcount trends, funding stage, technologies used, and even keywords or university. The platform enriches each contact automatically with titles, company information, and LinkedIn profiles, enabling marketers to create personalized messaging that resonates with specific segments. This data-driven approach to audience building improves campaign performance, increases engagement rates, and ensures marketing budgets are spent on reaching the most relevant potential customers.

Lead List Validation and Enrichment

Organizations with existing prospect lists can use Glasa to validate and enrich their contact data. Users can upload their own lists, and the AI agents will verify each email against live mail servers, check domain validity, and confirm the contact is a real person. Additionally, the platform automatically fills in missing information such as job titles, company details, and LinkedIn profiles. This use case is particularly valuable for companies that have accumulated contact data from various sources over time and need to clean and update their CRM before launching outreach campaigns.

Automated Outreach Campaign Management

Glasa serves as an all-in-one platform for managing complete outreach campaigns from discovery to booking. Users can find contacts, validate lists, build audiences, warm inboxes, send personalized email sequences, and manage replies all within the same interface. The unified inbox automatically categorizes leads by interest level, flags hot prospects, and auto-tags replies so users always know who to follow up with first. This end-to-end workflow eliminates the need to stitch together multiple tools and provides a seamless experience for go-to-market teams.

How does Glasa verify contact data?

Glasa employs a three-layer verification process for every contact. First, it performs a format check to ensure the email address structure is valid. Second, it conducts domain verification against live mail servers to confirm the domain exists and can receive mail. Third, it performs real person confirmation to ensure the contact is an actual individual at that company. This process is automated by AI agents that scan over 35 live data sources in real time, resulting in 99% email accuracy and less than 2% bounce rates.

Can I use my own email infrastructure with Glasa?

Yes, Glasa provides full flexibility in choosing your sending infrastructure. You can use Google Workspace, Microsoft Outlook, or SMTP, and you can even mix different providers within the same campaign. Additionally, Glasa offers an inbox marketplace where you can buy standard and warmed inboxes from trusted providers. This gives you complete control over which provider each inbox uses for both warmup and outreach activities.

What types of filters are available for finding contacts?

Glasa offers extensive filtering capabilities to help you find the exact prospects you need. You can filter by job title, company revenue, headcount trends, funding stage, technologies used, keywords, and university. You can also specify geographic location, company size, and industry. The platform provides access to over 800 million B2B contacts and 55 million companies, with data synced live from 35+ sources and never cached.

How does the AI agent for lead qualification work?

The AI agent uses natural language processing to understand your ideal prospect description. You can tell Glasa what you are looking for in plain language, such as "find me CTOs at B2B SaaS companies." The agent will then ask clarifying questions to narrow down criteria like company size and geography. Once specified, the agent automatically searches the database, validates each contact, and presents you with qualified leads that match your exact requirements, including verified email addresses and contact details.
