What Reply.io does
Reply.io is a San Francisco-based, privately held software company founded in 2014 by Oleg Bilozor that operates an AI-powered multichannel sales engagement platform used by more than 3,000 businesses worldwide. The core product automates cold outreach and follow-up across email, LinkedIn, calls, SMS, and WhatsApp within conditional sequences, and pairs this orchestration layer with a built-in email deliverability infrastructure that maintains a 98% inbox placement rate. The company also owns a proprietary real-time B2B database covering more than 1 billion global contacts with hiring and technographic intent signals, and ships a flagship autonomous AI agent, Jason AI SDR, capable of ICP definition, multichannel sequence generation, reply handling, and meeting booking in 24/7 autopilot or copilot modes across 50+ languages.
Underlying technology rests on eight documented AI capability categories spanning autonomous agents, generative AI, natural language processing, recommendation engines, predictive analytics, process automation, knowledge retrieval, and speech/audio, with user-selectable models from Claude, Gemini, Mistral, and OpenAI and a triple-verification layer for generated content. The platform exposes 38+ REST API endpoints via Reply API V3 and an MCP server for AI assistants such as Claude and Cursor, and integrates natively with HubSpot, Salesforce, Pipedrive, Copper, Zapier, Make, n8n, and LinkedIn Sales Navigator.
The business model is predominantly subscription-based, with pricing tiers from $49 to $1,200+/month segmented across Email Volume, Multichannel, AI SDR Starter/Growth/Enterprise, and Agency plans, plus credit-based AI & Live Data consumption, 15-25% lifetime affiliate commissions via Partnerstack, and white-label licensing for resellers. The company is bootstrapped save for a single $400,000 seed round in 2016, sells through a hybrid PLG/inside-sales motion supported by an agency partner network, white-label channel, and global affiliate program, and is certified SOC 2 Type II and GDPR compliant for enterprise and white-label deployments.
