This review breaks down the platform’s strengths, weaknesses, and the best alternatives available today.

What is Seamless.ai?

Seamless.ai is a B2B contact data platform that uses artificial intelligence to discover and verify business emails and direct dials in real time. It primarily pulls from LinkedIn via a Chrome extension and aims to help sales teams build lead lists and find decision-makers faster. Its value lies in instant lookup—but accuracy and usability are major considerations.

• Sales intelligence features – Tools like “Pitch Intelligence” offer context to help tailor outreach.
• Wide CRM compatibility – Seamless integrates with platforms like Salesforce, HubSpot, and Outreach.

• Opaque pricing – Pricing isn’t publicly listed, and unexpected charges are frequently reported.
• Support complaints – Many users struggle with billing disputes and delayed response times.
