What ESTsoft does
ESTsoft (KOSDAQ: 047560) is a Seoul-based software company founded in 1993 that has repositioned from a consumer utility-software vendor (the Altools suite — ALZip, ALSee, ALPDF, ALCapture, ALSong, ALDrive, ALYac M) into an AI human and conversational avatar provider under the Perso brand, while retaining a Cabal game-publishing franchise and a smaller asset-management business. Its core technology stack covers the full AI-human pipeline: Custom TTS (Korean-nuance and emotional voice), Face Creation (signature/premium/basic/photo/live/video avatars), STV (Speech-to-Video) lip-sync that aligns mouth movement to input audio, a Cultural Intelligence Engine for context-aware localization, and the Alan LLM, a multi-agent, RAG-capable enterprise model tuned for Korean. Perso Interactive combines these into a real-time conversational AI avatar supporting 100+ languages; Perso Dubbing delivers multilingual video localization with 32+ languages and 6,000+ voice options; STUDIO PERSO provides AI-driven 4K video production; Perso Interactive SDK enables enterprise and channel-partner integration.
ESTsoft serves a deliberately diversified customer base: tier-1 Korean and Japanese enterprises (Samsung, KT, NTT, Nihon Kotsu, SK Hynix, POSCO Holdings, Daewoo Construction), 10+ Korean universities via the AI-CODI platform (Hannam ~2B KRW, Keimyung 850M KRW), Singapore education and government channels via SCOOP, Canadian physical AI deployments via M2M Tech, and Korean public-sector programs via the 260B KRW AX One-Stop Voucher. A self-serve long tail — 120M creators using Perso AI Dubbing and 30M cumulative Altools users — provides volume and consumer reach alongside enterprise contracts.
Revenue is split across AI/SW services (Q1 2026: 150.8B KRW, +29% YoY — reported at a non-quarterly basis relative to the consolidated 30.98B KRW Q1 revenue, suggesting segment-level annual figures), Games (88.5B KRW in Q1 2026, +39.3% YoY on Cabal RED), Altools utility software (one-time consumer licenses plus an annual B2B AI Pack subscription), asset management (transaction fees, +17%), and AI education services (K-Digital Training). Q1 2026 consolidated revenue was 30.98B KRW, with operating loss reduced 61.8% YoY to 16.7B KRW and net loss down 85.4% to 6.9B KRW. Go-to-market mixes direct enterprise field sales, strategic channel partnerships (NTT Japan, SCOOP Southeast Asia, M2M Tech Canada), event-led demand generation (MWC, CES, AI EXPO, World IT Show), and government-voucher distribution.
