Efficiency is in our Name
Koritsu means efficiency, and it is the core philosophy behind everything we do. Koritsu AI was founded after seeing a recurring, expensive flaw in the tech industry: cloud budgets are being treated as an inevitable cost of doing business rather than a resource to be optimized.
We believe that high-growth engineering teams shouldn't have to choose between shipping code and saving capital. Our mission is to ensure your engineers are running applications as efficiently as possible, allowing your team to focus on innovation while adding the processes to guide accountability and efficiency.
Most companies find themselves overspending not by choice, but because they are caught in a gap between growth and visibility. This waste usually stems from a lack of structured FinOps processes to track spend in real-time, combined with the constant pressure of competing deadlines that push cost-optimization to the bottom of the backlog.
Furthermore, without deep, specialized cloud-native experience, it is difficult for many teams to define what "good" actually looks like for a modern infrastructure. We provide the strategy and expertise to bridge these gaps, turning your cloud spend into a competitive advantage.


Cloud Architect




15 Years of Development, 10 Years of Cloud, One Recurring Problem.
Koritsu AI was founded by Raphael Yoshiga, a software entrepreneur who spent over a decade building in the cloud. After auditing dozens of environments across AWS, Azure, and GCP, Raphael noticed a staggering pattern: No matter the industry, nearly 30% of every cloud budget was being wasted.
Coming from a software development background, Raphael realized that cost-cutting often failed because it was too disconnected from the engineering workflow. He founded Koritsu AI to bridge that gap—providing FinOps expertise that respects the speed of development.
"Cloud waste hits billions as 78% of firms report significant expenditure losses... Additionally, 51% of respondents estimate that over 40% of their cloud spend could be optimised".
