Sbl.so

Sbl.so (by Magillabs Technology Private Limited) is a full-stack LinkedIn outreach automation platform designed for B2B sales teams, solopreneurs, agencies, and recruiters who need to build a scalable and consistent outbound pipeline. Unlike basic automation tools that only send messages, Sbl.so combines AI-powered lead generation, hyper-personalized multi-channel outreach, autonomous conversation management, and fractional SDR (Sales Development Representative) networks into a single unified platform. It is marketed as the world's first complete LinkedIn automation tool, handling the entire workflow from finding leads to booking meetings without requiring manual intervention at every step.

How It Works

Sbl.so operates as an end-to-end outreach engine. Users describe their Ideal Customer Profile (ICP) in plain language, and the AI Lead Agent automatically finds matching high-quality B2B prospects from over 100 premium sources. Once leads are imported, AI-powered sequences handle the outreach across LinkedIn, WhatsApp, and email. After a prospect replies, an AI chatbot takes over the conversation: it answers questions, handles objections, qualifies leads, and books meetings automatically. The human seller only steps in for hot leads ready to close. According to Sbl.so, the AI manages 95–99% of all conversations without human involvement.

Key Capabilities

• AI Lead Generation: The Lead Engine finds unlimited ICP-matched leads from 100+ sources. Users can also paste a LinkedIn Sales Navigator or Recruiter search URL to extract leads automatically—no CSV exports or browser extensions required.
• Fractional SDR Networks: Users can deploy 1, 10, or 100+ fractional SDR profiles (real people who connect their LinkedIn profiles to a workspace) to multiply outreach volume. Each profile can send up to 75 connection requests and 200 messages per day. Profiles are automatically rotated when one hits daily limits.
• Autonomous AI Conversations: After an initial message, AI takes over replies in over 100 languages. It can send personalized voice messages (using AI voice cloning), images, PDFs, and videos based on conversation context. The system learns from human interventions and improves over time.
• Smart Sequencing & Pre-Suasion: Multi-touch sequences can include profile visits, post likes, comments, connection requests, and follow-up messages with randomized delays that mimic human behavior.
• LinkedIn Comment-to-DM: Automates the common "Comment and I'll DM you" lead generation tactic. Works on the user's own posts, competitor posts, and influencer posts.
• Unified Inbox & CRM: All conversations from all connected LinkedIn and WhatsApp accounts appear in a single inbox. Built-in CRM tracks deals and stages, with optional syncing to HubSpot, Salesforce, Pipedrive, Zoho, and other platforms via Zapier.
• Lead Scoring Agent: AI automatically scores and filters leads by budget, timeline, pain points, and decision-making authority before outreach begins, claiming 3x better response rates.
• Advanced Analytics: Campaign reporting includes conversion stage tracking, lead interest levels, buying intent signals, sentiment analysis, and qualitative chat insights. Real-time alerts notify users of hot leads, negative sentiment, and buying signals.

Safety & Compliance

Sbl.so differentiates itself on safety. The platform enforces LinkedIn's daily limits automatically (200 messages per day, 200 connection requests per week per profile, which users cannot override). Human-like behavior patterns add random delays between actions. New sender profiles undergo a gradual activity ramp-up over three weeks. Real-time health monitoring tracks acceptance rates, reply rates, and profile visit success, and auto-pauses campaigns if metrics drop. Sbl.so reports zero client bans since launch with a 99.7% safety rate across 50 million processed messages. If a fractional SDR profile is restricted, the platform offers a 48-hour replacement guarantee.

Intended Users

Sbl.so serves B2B companies looking to book more demos and qualify leads, recruiters and HR teams automating candidate outreach and screening, agencies and consultants managing multiple client brands through unlimited workspaces, and course creators and coaches promoting webinars, building communities, and enrolling students.

The platform integrates with LinkedIn Sales Navigator and Recruiter for lead extraction, HubSpot, Salesforce, Pipedrive, Zoho, and LeadSquared for CRM syncing, and over 3,000+ apps via Zapier and n8n. WhatsApp and email channels are built in, with phone outreach available.
