Li Cheng · Series-B founder, Shanghai 2 weeks ago

Yuki guided our team through a complicated JP→US carve-out on a tight timeline. Direct, no jargon, and the bilingual deal memos were a lifesaver for our China-side board.

Clear, fast, calm under pressure. We came in late on a SAFE round and Yuki turned around a clean redline in under 48h.
