Philosophy
Our Philosophy
Unlike typical outsourcing companies, RIS selects clients like an Activist Fund. We don't automatically accept all project requests. Instead, we carefully evaluate the client's leadership capabilities, corporate vision, and growth potential. We assess whether working together can create mutual synergy and if it's a business model that can grow long-term before deciding on project participation. With selected partners, we build strategic partnerships where we actively advise and grow together as equals, not just as contractors.
We don't simply take on projects for revenue. We believe in our clients' vision and potential, and invest in growing together. We quickly learn and apply the latest technology trends to always provide advanced solutions. Through continuous research and development, we create better services and achieve innovation together with the mindset that our clients' success is our success.
RIS's differentiated process starts before the contract. Based on extensive development planning experience, we provide free initial proposals optimized for your business. During this process, we thoroughly review whether the planning fits, and only proceed with a contract when both parties are satisfied. This is not just a formal meeting to win a project, but a time to verify actual feasibility and business value together. The contract is written with clearly defined requirements, preventing misunderstandings and disputes during development. Through transparent and systematic processes, we increase project success rates and build long-term trust relationships with clients.
Most large development companies use inexperienced junior developers for overnight work to maximize margins. In this process, quality management is often neglected, and customer requirements are not accurately reflected. RIS is a small but mighty company where a select group of experts directly handles projects. Senior developers with over 7 years of practical experience take full responsibility from start to finish. We compete on quality and expertise, not price. Through systematic schedule management and code quality control, we deliver stable results. We guarantee the highest quality through efficient development processes and expertise, not through overtime and all-nighters.

CEO Message
Realizing business growth with innovative technology

Hello, I'm Sunghyunjae, CEO of RIS. RIS is not just another IT outsourcing company. We are strategic partners who realize your vision together. Through 7 years of numerous projects, I've learned something crucial: truly successful projects aren't built on technical skills alone. They become possible when we deeply understand your business and have the will to grow together. That's why we select clients like an activist fund. We don't just take any project for money - we seek partners we can grow with. That's why we provide free initial proposals before contracts. We thoroughly verify if we're a good fit for each other, and only start together when we're confident. Most development companies use overnight work by inexperienced junior developers to maximize margins. But we're different. Senior developers with over 7 years of experience take full responsibility from start to finish. We guarantee the highest quality through efficient processes and expertise. From website creation, mobile app development, IT consulting to ERP construction - every service we provide is not just feature implementation, but strategic solutions for your business growth. We're ready to invest in your vision. If you're looking for a partner to grow together with, please don't hesitate to contact us. Sunghyunjae, CEO of RIS
