Persona AI: Edge AI Built to Run Without a GPU or Internet

What does Persona AI build?

The core business is the AI contact center: chatbots, voice bots (call bots), AI kiosks and a knowledge management system that help companies answer customers around the clock. Its customers include banks and insurers in Korea such as KB Financial Group, Shinhan, NH, Woori Bank, JB Financial Group and Jeonbuk Bank, and SK Telecom uses its AICC under its own brand, according to a May 2025 interview in THE ELEC. In a 2023 ZDNet Korea interview the CEO said the company served about 1,000 client companies, and that chatbots and call bots made up roughly 70 percent of revenue.

What is the core technology?

The company builds its own AI engine, called SONA, instead of building on a licensed or open source model. The CEO describes the engine as one that runs on a device without an internet connection and without a GPU. In Forbes Korea (July 2025) he said the key to making models light is quantization, and that the structure activates only the models needed to solve a problem. The company also lists a speech recognition engine trained on Korean voice data, small language models (sLLM) and an experimental vision-language-action model for robots. These performance claims come from the company and its CEO, and the press coverage cites no independent benchmark.

Where does the natural language technology come from?

Persona AI began as a conversation technology company. The CEO told ZDNet Korea in 2023 that he started AI research in 2015 after seeing that a large foreign company was training AI in Korean, and he judged that a Korean team could do Korean conversation better. The company built its own natural language engine, including a generation function that creates training data from documents, voice files or recordings of agent calls, so that a client does not need to supply labeled data. He also said that only about 3 percent of AI companies own their source engine. That is the CEO's estimate, not an independent figure, but the point is credible: most startups in this space build on open source or licensed models, and Persona AI has spent about nine years on its own.

Why edge AI?

In the Forbes Korea interview the CEO said the direction was clear to him from the start: "미래는 이미 정해져 있고, 엣지 AI를 할 수밖에 없었다" (the future was already decided, and we had no choice but to do edge AI). His reasoning is practical: if AI runs on the device, the customer's data does not leave the device, there is no per-use cloud cost, and AI can run where a GPU is hard to install, such as AI PCs and robots. In THE ELEC he said running AI on a robot without a GPU is very hard and that the company's engine can solve it.

What is the funding history?

The press coverage gives the following steps. In June 2023, Hyosung Ventures invested KRW 2 billion in the company, and the CEO told ZDNet Korea that cumulative investment at that time was KRW 8.5 billion. Over the following year SK Telecom and NAVER Cloud also invested. In April 2024, Mirae Asset Venture Investment, KB Securities and Korea Investment Partners joined a pre-IPO round with an undisclosed amount, reported by AI Times. In February 2026 the company raised a pre-IPO round of about KRW 12 billion, led by LIG Nex1 and IBK Capital through the Defense Innovation Fund, with DB Technology Investment, HB Investment and AIM Investment. Cumulative funding then stood at about KRW 41 billion. The company plans to use the funds for AI agent capabilities and for developing and commercializing physical AI.

How did the company get here?

The CEO told ZDNet Korea in 2023 that Persona AI is his third startup, after he founded a software company while still in high school. He began AI research in 2015, incorporated in March 2017 and renamed the company Persona AI in March 2020. He said the company nearly ran out of money in 2017 after a hacking incident, that it paid for its own and its clients' losses, and that it recovered by applying for government projects and commercializing its product. His stated mission is to make AI that ordinary people can use easily.

What recognition has it received?

The company reports CES Innovation Awards in two consecutive years, a place in the Ministry of SMEs and Startups Pre-Unicorn program in 2025, the Stone Tower Order of Industrial Service Merit, and a place in Forbes Korea's 2025 Korea AI 50.

What is next?

The company says it is preparing an IPO under the technology special listing route, with Mirae Asset Securities as lead underwriter, and plans to expand overseas with AI PCs, servers and robots that carry its own engine. In the Forbes Korea interview the CEO also described a consumer product that installs like an app on phones, laptops and PCs. For foreign partners, the relevant fit is hardware makers, robotics companies, financial institutions and public sector buyers that need AI to run on site, with data kept on the device.

Why do I see high investment value here?

This is my personal view, not investment advice. First, Persona AI owns an original natural language technology. Owning the engine means control over cost, over where the data stays and over how small the model can be made, which is hard for companies that depend on someone else's model. Second, the company is aiming that engine at physical AI. An engine that runs without a GPU or an internet connection fits robots and devices, where weight, power and connectivity are limits, and the February 2026 funds were earmarked for physical AI. Third, the AI contact center business gives the company paying financial-sector customers and recurring revenue while the newer business develops. Fourth, I expect the company to list on KOSDAQ soon. The company says it is preparing an IPO with Mirae Asset Securities as lead underwriter, and an investor who enters before a listing is buying the story before the market prices it. The risks are real. The technical claims lack independent benchmarks, physical AI is early, press figures on revenue are inconsistent, and the technology special listing track became more selective in 2026, so timing is not guaranteed.

What should a foreign investor or partner ask?

Four questions are worth asking in a first meeting. First, which parts of the stack are owned by the company and which are licensed. Second, what independent evidence exists for the speed and accuracy claims on the target device. Third, how much of revenue is recurring subscription rather than project work. Fourth, what the plan is for overseas distribution and support. These are my suggested questions, not statements from the company.
