Comparison
Leadline vs Apollo.io
Apollo is strong for broad B2B search. It is not built for exhibition directories or floor plan PDFs. Leadline starts from the confirmed exhibitor list.
What Apollo does well
Apollo.io is a large general B2B contact database, especially useful for US tech and SaaS prospecting with filters for title, industry, and company size.
Where Apollo falls short for trade shows
Apollo has no concept of exhibitor lists, booth numbers, or floor plan PDFs. For a show with 300–1,400 exhibitors you would search companies one by one — often 8 hours or more of manual work — with no way to upload a floor plan or filter by event participation.
Email accuracy in SME segments is typically lower than Leadline’s verified exports.
How Leadline is different
Leadline extracts every participating company from a floor plan, URL, or company list, then enriches each with verified emails, phones, and LinkedIn profiles. Typical turnaround: under 5 minutes instead of 8 hours of manual work.
