Questions about Second Brain

What does Second Brain do?

Second Brain is an AI SDR for LinkedIn outreach and meetings. It identifies high-intent buyers on LinkedIn, sends personalized messages, tracks replies and automatically books meetings with interested prospects. It runs on the web, through an API and on WhatsApp.

How much does Second Brain cost?

Second Brain's Monthly Plan costs $19 per month and includes auto outreach and meeting booking for SDR profiles. There is also an Annual Plan and a Custom Plan priced on contact, but no free tier. The reviewer notes that on-demand human oversight from dedicated experts costs extra.

What are the downsides of Second Brain?

The reviewer says Second Brain does not handle complex human interactions or objections well, so human oversight is still needed. It relies on pre-made SDR profiles that may not fit every sales style, and dedicated experts for oversight add extra cost.
