Generative AI Dramatically Transforms Business. I'm Convinced of It.
Takuya Tominaga
CEO, Leach Inc.
9 years at Toshiba R&D. Worked with Google and McKinsey on the front lines of data business. What I realized: no matter how far technology advances, day-to-day operations remain unchanged.
After leaving, I visited companies everywhere. People using rulers on monitors to reconcile data. Copy-pasting by hand, over and over. Upstairs, flashy AI discussions. Downstairs, humans exhausted. Generative AI can change this. I was instinctively convinced.
"We want AI but don't know where to start." If that sounds like you, please reach out. We'll look at your operations together and find the best path forward.
