About

Yosuke Higashi is a venture investor and startup ecosystem contributor serving as Founding Software Engineer at Citadel AI. His career has focused on advanced software systems, artificial intelligence, and the engineering challenges behind safety-critical technologies. Having worked both inside a global frontier-technology company and at an early-stage AI startup, Yosuke brings a rare builder perspective on technical product development, AI reliability, startup engineering, and the differences between developing technology in a venture-backed startup and at global scale. In practice, that perspective connects founder quality, market evidence, investment fit, and the long-term work required to build a company that investors can continue supporting. Yosuke is particularly relevant to conversations around fundraising readiness, investor decision-making, venture-scale growth, and the signals that help founders build conviction with capital partners.
