Glasa is an AI-powered customer intelligence platform designed to solve the fundamental challenge of finding and connecting with high-intent prospects. It serves as an all-in-one go-to-market (GTM) platform that helps businesses detect, find, and connect with their ideal consumers without the need to stitch together multiple tools. By leveraging advanced artificial intelligence, Glasa identifies high-intent prospects, uncovers actionable insights, and streamlines outreach across multiple communication channels. The platform is built for modern GTM teams, including sales, marketing, and revenue operations professionals who need to refine audience targeting, personalize engagement, and align their teams around high-value opportunities. Glasa offers access to over 800 million pre-validated B2B contacts across 55 million companies, with AI agents that scan 35+ live data sources in real time to verify email deliverability and enrich profiles automatically. This ensures a 99.2% deliverability guarantee and less than 2% bounce rates. The platform combines real-time data analysis with intelligent targeting, enabling companies to increase conversion rates, improve marketing efficiency, and accelerate revenue growth. Glasa prioritizes privacy and security, employing responsible data practices while delivering scalable, performance-driven solutions. From finding contacts and validating lists to warming inboxes and sending personalized sequences, Glasa consolidates the entire prospecting and outreach workflow into a single, unified platform.

AI-Powered Contact Discovery and Qualification

Glasa uses advanced AI agents that allow users to browse from over 800 million pre-validated contacts and find leads in minutes. Users can simply describe their ideal prospect using natural language, specifying criteria like industry, job title, company size, and geography. The AI agents then scan 35+ live data sources, verify email deliverability against live mail servers, and enrich each profile with accurate titles, company information, and LinkedIn details. This eliminates the need for manual research and ensures that every lead hitting your pipeline is validated before you spend any credits.

Triple Verified Contact Validation

Every contact in Glasa undergoes a rigorous three-layer verification process before you hit send. This includes format check, domain verification, and real person confirmation, ensuring 99% email accuracy and 95% title accuracy. Users can see the validation status of each contact before checkout, so they know exactly what they are paying for before it hits their balance. The system scans live mail servers to confirm deliverability, resulting in less than 2% bounce rates and eliminating wasted time and resources on bad data.

Unified Inbox with AI Lead Categorization

Glasa provides a single, unified inbox where AI automatically categorizes leads by interest level, flags hot prospects, and auto-tags replies. This allows sales and marketing teams to always know who to follow up with first, prioritizing high-value opportunities. The platform consolidates the entire outreach workflow, from finding contacts and validating lists to warming inboxes, running sequences, and managing every reply in one place. This eliminates the need for separate tools and manual lead sorting, significantly improving response times and conversion rates.

Flexible Sending Infrastructure and Inbox Marketplace

Users have full control over their sending infrastructure, with the ability to choose Google Workspace, Microsoft Outlook, or SMTP/Custom providers. Glasa allows users to mix providers within the same campaign and even buy standard and warmed inboxes directly from trusted providers inside the platform. This flexibility ensures optimal deliverability and allows teams to scale their outreach without worrying about sender reputation. Each contact's email provider is displayed, so users know exactly how to reach them effectively.

Building Targeted Prospecting Lists for Sales Teams

Sales teams can use Glasa to build highly targeted prospect lists in minutes by simply describing their ideal customer profile. A sales rep looking for CTOs at B2B SaaS companies with 50 to 500 employees in the US can get a validated list of contacts with triple verified emails and direct dials. The AI agents automatically filter by job title, company revenue, headcount trends, funding stage, technologies used, and keywords, ensuring every contact matches the exact criteria. This eliminates hours of manual research on LinkedIn and other databases, allowing reps to focus on closing deals.

Validating and Cleaning Existing Contact Databases

Marketing and revenue operations teams can use Glasa to validate and clean their existing contact databases before running campaigns. Instead of sending emails to stale or outdated contacts that hurt deliverability scores, teams can upload their lists and let Glasa's AI verify each email against live mail servers. The platform identifies invalid, undeliverable, and risky addresses, ensuring only high-quality contacts remain. This reduces bounce rates, protects sender reputation, and improves overall email campaign performance by ensuring messages reach real, engaged recipients.

Automating Multi-Channel Outreach Sequences

GTM teams can use Glasa to automate personalized outreach sequences across multiple channels without manual intervention. After building a validated audience, users can set up AI-driven sequences that warm inboxes, send personalized emails from chosen sending infrastructure, and manage replies in the unified inbox. The AI automatically categorizes incoming responses by interest level, flagging hot prospects for immediate follow-up while routing less urgent replies accordingly. This streamlines the entire outreach process, ensuring consistent follow-up and maximizing the chances of converting leads into customers.

Integrating Contact Data into Existing Tech Stack

Developers and engineering teams can use Glasa's REST APIs to plug email verification and contact finder functionality directly into their own stack. The Verification API allows teams to validate emails programmatically, while the Finder API enables automated contact discovery. This is ideal for high-volume pipelines where manual data processing is impractical. Companies can build custom integrations, automate lead enrichment workflows, and ensure their CRM or marketing automation platform always has accurate, up-to-date contact information without manual data entry.

How does Glasa ensure the accuracy of its contact data?

Glasa employs a rigorous three-layer verification process for every contact. First, it performs a format check to ensure the email structure is valid. Second, it conducts domain verification to confirm the email domain exists and accepts mail. Third, it performs real person confirmation by pinging live mail servers. Additionally, AI agents scan 35+ live data sources in real time to enrich profiles with accurate titles, companies, and LinkedIn details. This results in 99% email accuracy, 95% title accuracy, and less than 2% bounce rates.

Can I use my own email accounts for outreach with Glasa?

Yes, Glasa offers full flexibility in choosing your sending infrastructure. You can connect your Google Workspace, Microsoft Outlook, or any SMTP/Custom provider. The platform also allows you to mix different providers within the same campaign, giving you full control over which provider each inbox uses. Additionally, Glasa has an inbox marketplace where you can buy standard and warmed inboxes from trusted providers directly inside the platform if you need additional sending capacity.

What kind of filtering and targeting options are available?

Glasa provides extensive filtering capabilities to help you find exactly the right prospects. You can filter by job title, company revenue, headcount trends, funding stage, technologies used, keywords, and university. The AI agents also allow natural language queries, so you can simply describe your ideal prospect. Every contact includes a triple verified email and direct dial, and you can see each contact's email provider to know exactly how to reach them. Data is synced live from 35+ sources and is never cached.

Is there an API available for integrating Glasa with other tools?

Yes, Glasa provides full REST API access for both email verification and contact finding. The POST /v1/verify endpoint allows you to programmatically verify email addresses, returning whether the email is valid and deliverable. The GET /v1/find-email endpoint enables automated contact discovery. These APIs are built for high-volume pipelines, allowing you to plug Glasa's functionality directly into your own tech stack, CRM, or marketing automation platform for seamless data integration and enrichment.
