This is Addsoft

Addsoft opened in November 2020 in Icheon, Gyeonggi-do. Application software development is our core business, and we have built enterprise systems and customer-facing web services since day one.

Before the company, the work began in 2004 with retail IT operations and moved on to C/C++ — SNMP network management systems, telecom equipment management engines, digital camera test automation, network-separation security products and Windows kernel drivers. That time close to devices, networks and the operating system is why we can also take on older C/C++ and MFC programs that nobody left behind can maintain.

We have also worked alongside partner companies on enterprise solutions — multi-tenant SaaS with single sign-on, commerce and warehouse systems, NFC-driven field inspection, and document search AI that runs entirely on in-house servers.

More recently we have planned and shipped our own Unity mobile games and web services — along with the platform that runs our tech blog, a service that watches our certificates, domains and mail servers, and developer tools anyone can download. We use all of them every day. Running our own products keeps us honest — and that experience goes straight back into client work.

Because we work as a small team, decisions are quick and requirements don't get distorted as they pass between people. That fits projects where a large SI vendor would be overkill.
