What 3Sigma does

3Sigma is a mobile-first WhatsApp-integrated sales CRM designed for Indian small and mid-sized businesses. The platform unifies lead capture from 25+ India-specific sources (IndiaMART, JustDial, 99acres, MagicBricks, Facebook Lead Ads, Google Lead Forms), WhatsApp Business API communication with a shared team inbox, SIM-based auto-dialer using the user's own phone line, visual pipeline management, automated follow-up sequences, and quotation/invoice generation with embedded Razorpay payment links. Available on Web, Android (Play Store), and iOS (App Store), the product is positioned specifically for smartphone-first sales teams rather than desktop-centric office workers, distinguishing it from global horizontal CRMs.

The underlying technology stack combines WhatsApp Business API integration (including a Coexistence feature that preserves existing WhatsApp Business chat history), webhook-based real-time lead ingestion, SIM-based telephony with dual-SIM and crash-proof session resume, and cloud-synced pipeline data across devices. The product covers the full SMB sales workflow from lead import through WhatsApp/call engagement, pipeline progression with stuck-deal alerts, weighted forecasting, and payment collection—targeting verticals including real estate, education, financial services, manufacturing, insurance, solar energy, and telecalling.

3Sigma monetizes through a freemium SaaS subscription (Free, Premium+ ~₹2,000/user/year, Ultimate ~₹3,000/user/year) with a 7-day no-credit-card trial, supplemented by passthrough revenue from Razorpay payment processing fees and Meta WhatsApp Business API conversation charges. Go-to-market combines product-led growth via app store downloads with sales-assisted conversion through Calendly demos, targeting an active base of 20,000+ businesses and 50,000+ app downloads. The company is privately held and bootstrapped with no disclosed institutional funding and 1-10 employees based in Gurgaon, India.
