Neosapience's core business is Typecast, an AI voice generation platform that converts text into emotionally expressive speech.
Its deep-learning TTS engine analyzes contextual cues to produce voices that carry emotion and intonation across 720+ proprietary AI voice IPs, offered via web/app subscriptions and enterprise API.
As of H1 2026, the Typecast web/app channel accounted for 84.8% of revenue and the API channel 9.1%; B2C subscribers represent roughly 70% of revenue by volume, yet the CEO notes each B2B customer generates approximately 100x the revenue of a single B2C subscriber, making B2B expansion the strategic priority.
Over 2,000 Korean enterprises — including the top-three telecoms and top-three terrestrial broadcasters — use Typecast, and monthly recurring revenue has grown approximately 11-fold over four years.
The key technical moat is an internally developed end-to-end stack integrating STT, LLM, and TTS, which the company says reduces compute costs by more than 65% versus assembling third-party APIs; this is partly reflected in Typecast's ~80% contribution margin.
The next-generation service 'Neona' extends beyond generation to full-cycle real-time dialogue — listening, reasoning, and speaking — targeting B2B verticals such as AI tutoring, AI contact centers (AICC), and physical AI, while also pursuing a B2C AI companion app.
On the competitive front, the CEO has stated that despite aggressive domestic market entry by global voice AI companies valued above KRW 15 trillion, Neosapience has retained its position as Korea's top voice AI by MRR.
The 2023 U.S. subsidiary incorporation and the July 2026 entry into the AWS Marketplace establish a foundation for North American B2B expansion.
