Frequently asked questions
Is Prospect AI's database larger than Seamless.AI's?
Prospect AI maintains 530M+ pre-verified contacts. Seamless.AI uses a real-time search model that finds contacts on demand rather than maintaining a static database. Both approaches have trade-offs: Prospect AI's pre-verification means faster delivery and lower bounce rates.
Does Seamless.AI's Autopilot do the same thing as Prospect AI's AI?
Seamless.AI's Autopilot assists with writing sales copy. Prospect AI's AI goes much further; it researches each prospect individually, writes unique messages, executes multi-channel outreach, handles objections, and books meetings. They're fundamentally different levels of automation.
Which is better for cold email outreach?
Prospect AI includes email infrastructure (custom domains, warmup, deliverability monitoring) that Seamless.AI doesn't offer. This means Prospect AI emails are more likely to reach the inbox. Combined with AI personalization, Prospect AI typically achieves higher reply rates.
Can I get started with Prospect AI as quickly as Seamless.AI?
Seamless.AI offers instant self-serve access. Prospect AI requires a brief onboarding call to configure your ICP and infrastructure, but the team handles all setup. Most customers are running campaigns within 24 hours.
Does Prospect AI offer a free tier like Seamless.AI?
Prospect AI doesn't offer a free tier but provides demos with real AI-researched messages for your actual target accounts. This shows you exactly what the platform delivers before committing.
