SDR.io — AI SDR for LinkedIn, Email, WhatsApp & Voice

SDR.io by Mantra AI — The Autonomous AI SDR That Qualifies, Researches, and Reaches Out On Every Channel SDR.io is an AI SDR that does the full job of a sales development rep — autonomously, or with you in the loop. It qualifies leads against your ICP, researches them deeply, and runs hyper-personalized outreach across LinkedIn, email, WhatsApp, and voice calls — on a schedule you set. Use it in the browser as a real-time copilot on every LinkedIn profile and website. Or let it run on its own and just review what it booked. Built by Mantra AI — the team behind a suite of AI-native products for modern revenue teams. Install free. No credit card. Your AI SDR is working before lunch. One Product, Two Modes Autonomous Mode — Define your ICP and channels. SDR.io sources prospects, scores them, enriches contact info, researches each account, writes personalized outreach, and runs multi-channel sequences across LinkedIn, email, WhatsApp, and voice. You review replies and meetings, not busywork. Copilot Mode — Prefer human-in-the-loop? The Chrome extension turns every LinkedIn page and website into an intelligence panel. Score, enrich, research, and push qualified leads into outreach with one click. You stay in control of every send. Most teams run both — autonomous for top-of-funnel volume, copilot for high-value accounts. What an AI SDR Actually Does (the full job, not just scoring) 1. Qualifies Real-time ICP scoring (0–100) on every profile and company, with transparent + and − signals: industry fit, geography, role, tenure, headcount growth, funding, hiring velocity, tech stack, traffic trends. No black box. 2. Researches For every qualified lead, SDR.io pulls deep account intelligence — headcount, HQ, founding year, specialties, tech stack, traffic and SEO data, recent news, funding events, leadership changes, and a full decision-maker map (CEO, CRO, CFO, CHRO, VPs) ready to multi-thread. 3. Reaches Out — On Every Channel, Hyper-Personalized Email — verified work addresses, deliverability-aware sending, personalization built from the actual research (not "I saw your company on LinkedIn") LinkedIn — connection requests, InMail, and follow-ups timed to behavior WhatsApp — direct, opt-in compliant outreach on the channel buyers actually read Voice calls — AI-driven calls with natural conversation, qualification, and meeting booking Every message is written from the research SDR.io did on that prospect — their role, their company's funding round, their tech stack, their recent news. Not templated. Not "Hi {{first_name}}." 4. Sequences and Adapts Multi-touch, multi-channel sequences that branch on reply behavior. If email bounces, it tries LinkedIn. If LinkedIn is silent, it tries WhatsApp. If the prospect engages, it escalates to a call. The SDR brain decides the next move.
