Overview
Glasa and ProspectHalo are AI-powered sales and lead generation platforms, but they take fundamentally different approaches. Glasa is a customer intelligence platform centered on a massive database of 800M+ pre-validated B2B contacts, offering AI search, email verification, inbox warmup, and multichannel outreach. ProspectHalo is an AI sales agent that turns LinkedIn into a revenue engine by learning your business from your website, finding prospects on LinkedIn or Sales Navigator, and running automated outreach and content creation.
In short, Glasa is built for teams that need a reliable, large-scale source of verified contact data and email-centric outreach. ProspectHalo is designed for founders, agencies, and sales teams who want to leverage LinkedIn for prospecting and inbound content, with a focus on buying signals and personalized engagement.
