Webaresoft

What Webaresoft does

Webaresoft (위베어소프트) is a South Korea-based middleware software company founded in June 2021 by three former TmaxSoft researchers led by CEO Jang Young-hwi. The company develops API management and certificate lifecycle solutions built on a self-developed Rust-based API Gateway, marketed as APINEX (formerly OSORI APIM) and CertBear. APINEX provides end-to-end API lifecycle management — including gateway, portal, manager, authentication/authorization (API Key, OAuth, mTLS), load balancing, rate limiting, OAS-based documentation, and real-time dynamic configuration without service downtime — and is offered across on-premise, Store, and SaaS deployment models. CertBear, co-developed with BetweenSoft (Bitwinsoft), automates SSL/TLS certificate discovery, issuance, renewal, and pre-expiry alerting for organizations managing large certificate inventories; it received GS (Good Software) Certification Grade 1 in June 2026 and uniquely supports WAF integration among domestic competitors.

The company operates primarily through enterprise field sales targeting financial institutions (banks, insurance, securities), public-sector buyers, and large corporations, augmented by accelerator-driven pipeline development (IBK ChangGong, Woori Financial Dino Lab, KB Starters Singapore) and government procurement channels (조달청 Digital Service Mall, Venture Nara). Revenue streams include APINEX platform subscriptions across three deployment models, CertBear subscriptions, and Data Voucher program service revenue as a Ministry of Science and ICT-approved supplier. 2024 revenue was KRW 1.09 billion (~USD 0.8M), up 240% year-over-year on 14 contracted projects; the company has publicly targeted KRW 30 billion for 2025. Capital sources include seed rounds from Hanyang University Technology Holdings, SparkLabs, and CNTTech/DB Capital in 2024, plus Pre-Series A from Horizon Investment in May 2026. The company is actively expanding into Southeast Asia (Indonesia, Thailand, Singapore) via the KGlobalHub channel partnership, with active PoCs at Indonesian and Thai government institutions.

Webaresoft serves a focused enterprise and public-sector customer base in Korea and Southeast Asia, with approximately 1–10 employees as of late 2024 and a leadership team drawn from TmaxSoft's middleware practice. Its competitive positioning rests on a claimed first-mover advantage in zero-defect Rust middleware development in Korea, validated performance advantages (78% performance lift, 87% memory reduction, up to 50% cloud cost savings vs. Java-based competitors per DB Cloud PoC), and an expanding portfolio of public-sector and financial-sector references including Heungkuk Fire Insurance, D.B. Financial Group, and Korea Automobile Research Institute.

Core offering

Webaresoft develops and sells APINEX, an API integrated management platform built around a self-developed Rust-based API Gateway and available as on-premise, store, and SaaS deployments, covering API creation, publishing, authentication, load balancing, rate limiting, monitoring, and OAS-based documentation. The company also sells CertBear, an SSL/TLS certificate lifecycle automation solution co-developed with BetweenSoft (비트윈소프트) that handles certificate discovery, renewal, and pre-expiry alerting for both public and private CAs.

Product overview

Webaresoft operates a two-product portfolio: APINEX (formerly OSORI APIM) is the core API management platform providing an integrated API Gateway, Portal, and Manager for API creation, security, and monitoring, available as on-premise, store, and SaaS models. CertBear is the SSL/TLS certificate automation management solution that handles certificate discovery, issuance, renewal, and deployment for both public and private certificates, with agent-based infrastructure scanning and multi-channel alerting. The two products are complementary — APINEX manages API operations and security while CertBear ensures the TLS/SSL infrastructure underpinning those APIs remains valid and automated. Both products are Rust-based where applicable, and the company targets financial, public sector, and enterprise customers in Korea and Southeast Asia.
