SOOHO
SOOHO began as a Korean smart contract security auditor and has since expanded into broader stablecoin and digital-asset infrastructure, with its Reagent product still monitoring contracts for exploits.

SOOHO (SOOHO.IO), founded in Seoul in 2018 by CEO Jisu Park and backed in part by ConsenSys, built its reputation as a smart contract security auditor. Its Odin vulnerability-verification engine, combined with human auditors, has audited code for the IT arms of major Korean conglomerates including Samsung SDS, SK Inc. C&C, and LG CNS, as well as blockchain projects like Belt Finance and Bifi.
The company has since broadened its business into stablecoin and digital-asset financial infrastructure — products like Ezys (stablecoin payments) and Purplace (purpose-bound money) now sit alongside its security line. Its security product, Reagent, continues that original auditing DNA as an AI-based monitor that watches deployed smart contracts continuously for exploit attempts rather than auditing only at launch.
SOOHO has raised roughly $9 million to date, most recently signing a strategic agreement with global settlement network Partior in August 2026. Because the company’s core business has diversified well beyond pure-play security into building its own financial rails, its long-term identity as a security vendor is less clear-cut than when it first raised funding as a dedicated auditing platform in 2022.
Innovation Matrix Assessment
Reagent's continuous, AI-based contract monitoring is a reasonable evolution of the original auditing product, though company focus has broadened away from pure security R&D.
Smart contract security auditing has real value for blockchain-based financial products, particularly as SOOHO builds its own stablecoin rails that need the same protection.
Real named enterprise audit clients in Korea's IT sector and a new Partior settlement-network partnership signal expansion, but momentum is now split across security and non-security business lines.
Smart contract auditing is a known category with established competitors like CertiK and Trail of Bits; SOOHO is a credible participant, not a clear category leader.
A long operating history with recurring named enterprise audit clients (Samsung SDS, SK C&C, LG CNS) suggests real-world reliability for its core auditing product.
The company's strategic pivot toward building its own stablecoin infrastructure raises real questions about how central security auditing will remain to its business over the next several years.
Why CISOs Should Care
Offers continuous, not just point-in-time, monitoring of deployed smart contracts for exploit attempts, relevant to any organization running blockchain-based financial products.
What Makes It Different
Combines a decade of Korean enterprise smart contract audit experience with continuous post-deployment monitoring, rather than one-time audits alone.
The Matrix Verdict
47/100 — EMERGING / UNRANKED
An Emerging/Unranked company: SOOHO's original security product has real, verifiable enterprise traction, but its broader pivot into stablecoin infrastructure dilutes its identity and forward focus as a security vendor.
Editorial Note: Claims vs. Verified Findings
Named audit customers and the original $4.5M Series A are independently corroborated by press coverage (CoinDesk); the company's current primary business focus has shifted toward stablecoin infrastructure per its own current site, which is reflected in the conservative scoring here.
