What Blumn AI does

Blumn AI (블룸에이아이) is a Korean SaaS company that provides AI-powered customer communication solutions for businesses across chat, voice, and messaging channels. The entity was formed through the March 2025 statutory merger of two 2016-founded Korean SaaS firms — LUNASOFT and MBI Solution — with the combined company officially rebranding from Lunasoft-MBI Solution to Blumn AI in May–June 2025 under an AI Transformation (AX) strategy. The platform serves approximately 27,000+ enterprise customers and 70,000+ total customers, with named flagship accounts including Korail, Woowa Brothers (Baemin), and Musinsa on the enterprise side, alongside a long tail of Korean e-commerce merchants and SMEs. The platform reports processing roughly 160 million KakaoTalk biz-messages per month with a stated 97%+ CS solution customer retention rate.

The product portfolio is organized as a 'Switch-ON AI' modular layer applied across six core SaaS products: Happytalk (AI chat consultation and chatbot), CallBridge (AI phone consultation, rebranded from SangdamCall in March 2026), SmartMessage PLUS (CRM marketing), LunaM (KakaoTalk AlimTalk notification), Happysync (Kakao Sync customer engagement), and Heythere (on-site marketing). Underlying AI capabilities include the proprietary hAI (Happytalk AI) CS-specialized generative AI engine built on LLM and RAG, a proprietary Agentic RAG pipeline with patent applications pending, the AIVY AI Agent for 24/7 autonomous service across chat and voice, PAPYRUS real-time speech-to-text, the LOTUS knowledge base, and the no-code IVY AI-flow Builder. The architecture is deployed on AWS (Amazon MSK, Redshift, Bedrock with Claude 3.5 Sonnet and Titan foundation models, Transcribe, Polly) and supports a BYOA (Bring Your Own AI) strategy with open third-party integration (e.g., ElevenLabs for voice).

Revenue combines recurring SaaS subscriptions with usage-based revenue from KakaoTalk biz-messages (AlimTalk, Friend Talk). Go-to-market is sales-led through direct enterprise sales, inside sales for SMB, and channel partnerships including Kakao Official Dealer status, Cafe24 for e-commerce merchants, and the flagship June 2026 LG Uplus telco partnership targeting SME and mid-market AICC adoption. Pricing is quote-based and not publicly disclosed; SMEs can access up to 80% (max KRW 10M) subsidy through the 2025 SME Cloud Voucher program. Combined FY2024 annual revenue crossed 30 billion KRW for the first time — described as a record — across three business divisions (biz-message, customer consultation, CRM marketing), with an ongoing Series C round (~15 billion KRW) directed at AI R&D and Japan market entry.
