## Overview

Second Brain Labs is the company behind Sbl.so, an autonomous AI SDR platform for outbound sales. The site now lives at sbl.so, and the product has narrowed into a clear proposition: run LinkedIn and WhatsApp outreach at scale without putting your own account or your team's calendar at the mercy of manual copy-paste follow-up. The core mechanic is a fleet of dedicated, pre-warmed SDR profiles — described as carrying zero account bans across 50 million-plus messages sent — so outreach volume grows without risking the founder's or a rep's personal network.

Getting started is deliberately simple. You define your ideal customer profile in plain English or import a Sales Navigator search, and the platform builds a live lead list from buying signals such as job changes, funding announcements and competitor monitoring rather than from purchased lists. The AI then opens from your sender profiles in a conversational tone, uses voice clones and rich media where appropriate, handles replies and objections, and flags hot leads for human handoff when needed. Qualified buyers book directly into the calendar over Google Meet.

Under the hood it packages roughly 18 tools into a single subscription: lead generation, AI outreach, managed sender profiles, a unified inbox, a built-in CRM with booking, advanced analytics, multi-channel sequencing and agency-grade workspaces. The platform is marketed heavily at founders running outbound without a sales hire, sales teams wanting more meetings per rep, and agencies who need a separate, isolated workspace and sender profile per client.

## Pricing & Plans

Free trial and paid plans. There is a 7-day free trial with no credit card required and a 90% money-back guarantee mentioned on the site, plus recurring promotions such as 20% off the first three months. Plans appear to be tiered by volume and features, so check the Sbl.so pricing page for current numbers.

## Key Features & Capabilities

- **Autonomous AI SDR profiles:** Outreach runs from dedicated, pre-warmed sender profiles that rotate automatically, so your personal LinkedIn account is never at risk.
- **Intent-based lead generation:** The platform watches LinkedIn for buying signals, including job changes, funding news and competitor engagement, and builds a live lead list that updates daily.
- **Conversational AI that books meetings:** AI opens in your voice, handles replies and objections, and books qualified buyers straight into your calendar over Google Meet.
- **Multi-channel outreach:** Reach prospects on LinkedIn, WhatsApp, email or phone, with personalization, AI voice notes and sharing of images, video and files.
- **Unified inbox and built-in CRM:** Every conversation and meeting lands in one place with two-way CRM sync, real-time analytics, mobile app and unlimited workspaces.

## Primary Use Cases

- **Book meetings while you build the product (Founders doing their own outbound):** Run a full outbound motion without hiring an SDR: define an ICP, let AI handle follow-up 24/7, and keep your personal LinkedIn account clean.
- **More meetings per rep without more headcount (Sales teams):** Fill every rep's calendar with intent-qualified buyers, letting AI handle replies, objections and follow-up sequences so reps focus on closing.
- **Run every client from one dashboard (Agencies and consultants):** Give each client an isolated workspace and sender profile, scale outreach across accounts, and show real pipeline in reviews.
- **Reach buyers on LinkedIn and WhatsApp (Teams selling in messaging-first markets):** Combine LinkedIn conversations with WhatsApp follow-up so prospects are reached on the channel they actually reply to.
- **Keep the CRM updated automatically (RevOps and CRM owners):** Enrich company and contact data, score opportunities, and push qualified leads into your CRM automatically instead of manually updating records.

## Strengths

- Sends from dedicated SDR profiles rather than your personal LinkedIn account, which addresses the biggest risk in outbound automation
- Lead list is built from intent signals instead of purchased lists, so reply rates are higher
- Bundles lead gen, outreach, sender profiles, inbox, CRM and analytics into one subscription instead of stacking tools
- Agency-ready with unlimited workspaces and a separate profile per client

## Limitations

- LinkedIn automation always carries platform-policy risk, even with the account-safety design
- The full value depends on ICP definition and message quality, so setup effort is not trivial
- Pricing is quote-driven, so you need to talk to sales to compare plans properly at scale
