Read this if you run AI for a bank, media group or manufacturer in Korea or Japan and need agents grounded in internal documents. Sionic AI has about 50 staff, offices in Seoul and Tokyo, and a sales tie-up with a large Korean cloud provider. It is a platform vendor, not a model lab.
Sionic AI is a Seoul-based enterprise AI company founded in May 2023 and led by CEO Sukhyun Ko. Its STORM platform lets business teams build and run AI agents on their own company data without code, deployed on-premise, in a private cloud or as SaaS. It also sells document-parsing and retrieval APIs.
Founded: 2023 · HQ: Seoul, South Korea · Team: 50-100 · CEO: Sukhyun Ko · Funding: KRW 25 billion round in Dec 2025 (about USD 18 million), total above KRW 30 billion (lead: Atinum Investment, LB Investment)
About Sionic AI
Sionic AI is a Seoul enterprise AI company that its own company page dates to May 2023 (Businesskorea says 2022, so HokAI follows the company). It is headquartered in Gangnam-gu, Seoul, with a second office in the Toranomon district of Tokyo. The executive team listed on the site is CEO Sukhyun Ko (also romanised Seok-Hyun Koh), CDO Woomyoung Park and CSO Sihyeung Han, and the company page reports about 50 employees.
The main product is the STORM Platform, a no-code builder where business teams design and deploy agents grounded in internal documents, starting from pre-built templates. It ships in containers and can be installed inside a customer network, hosted privately or used as a service, which is the pitch to banks and public bodies with strict security rules. Two APIs sit beside it: STORM Parse, which turns unstructured documents into clean data for retrieval-augmented generation (RAG), and a retrieval pipeline with automated tuning. The vendor describes its grounding approach as designed to cut hallucinations; that is a vendor claim, and no independent benchmark has been published. Sionic AI lists past work such as a Q&A chatbot for a major travel company and a product recommendation chatbot, and says it serves finance, media, manufacturing and public-sector customers without naming most of them.
Funding came in two stages: a USD 4 million round in 2024 and a much larger round in December 2025. The investor list and amounts are in the funding answer below. Sources disagree on the cumulative total, so the funding field uses the figure Businesskorea reports and the valuation stays blank.
Distribution runs through partners. In September 2024 the company signed a memorandum of understanding with Alibaba Cloud aimed at Japan, China and Southeast Asia, and it is expanding a joint go-to-market effort with Naver in Korea and abroad. The CEO told Businesskorea the goal is to become a leading enterprise AI provider in the APAC region by 2030. That is a target, not a result.
Sionic AI is an application-layer vendor rather than a model lab. Korean model builders such as Upstage train their own language models, while Sionic AI's site describes taking large language models and fitting them to company workflows. Its strengths on paper are deployment flexibility and a no-code agent builder. Its limits are a team of about 50, no security certifications listed on the pages HokAI read, and no public pricing, so buyers need to ask for a quote.

Frequently Asked Questions
How much funding has Sionic AI raised?
Sionic AI reported a KRW 25 billion round (about USD 18 million) in December 2025, taking total capital raised above KRW 30 billion, according to Businesskorea. Atinum Investment and LB Investment led it, with ten investors including Naver Cloud and IBK Industrial Bank of Korea. An earlier 2024 round of USD 4 million came from Korea Investment Partners, IMM Investment, Samsung Venture Investment and Hillspring Investment. No valuation is disclosed.
What products does Sionic AI make in 2026?
The STORM Platform is a no-code builder for company AI agents, aimed at business teams in finance, media, manufacturing and the public sector. STORM Parse converts unstructured documents into data for retrieval, and a retrieval API tunes itself over time. Sionic AI publishes no prices, so every plan is a quote through contact@sionic.ai.
How does Sionic AI handle data privacy and compliance?
The pages HokAI read list no certifications such as SOC 2 or ISO 27001 and no trust center, so none are recorded here. What the company does state is deployment choice: on-premise, private cloud or SaaS, so sensitive data can stay inside a customer network. Ask for audit documents before a regulated rollout.
Who are the main competitors of Sionic AI?
Upstage competes in Korean enterprise document AI, and Naver Cloud sells its own enterprise AI tools while also acting as a Sionic AI partner. Sionic AI wins on deployment flexibility and a no-code builder for non-engineers. It trails on scale, with about 50 staff, and on proof, since no independent accuracy benchmarks or certifications are published.
How do you start using the products of Sionic AI?
Email contact@sionic.ai to discuss a deployment, or sign in to the STORM console through the link on sionic.ai. The company also runs a public STORM Parse playground that lets you test document parsing with your own file before talking to sales. Expect a sales-led setup rather than a self-serve checkout.
