He is an asset for any team, especially regarding the Japanese market." — Stephan O., Founder, AI App ⭐⭐⭐⭐⭐ 📝 VOICES FROM PROSPECTS [A WHOLE NEW PERSPECTIVE] "Yoshiki asked questions that we'd never even thought about. He used easy-to-understand language so someone with zero marketing experience like me could actually get it. Definitely worth the time!" — Founder, US-based SaaS ⭐⭐⭐⭐⭐ [RICHES IN THE NICHE] "I was confident in my language learning app and thought Japan would like it because another market did. It wasn't the case. Yoshiki suggested that my target was too broad and that no one would think 'oh, this is for me!'. He showed me how to narrow down my audience to shrink the competition—making my product the only logical solution." — Co-founder, Australian App ⭐⭐⭐⭐⭐ [PAIN-DRIVEN APPROACH] "Yoshiki helped me learn that our target didn't really have a massive pain. He taught me how Japanese are pain-drive rather than benefit-driven and that cultural context is what we were missing. Another lesson learned!" — Marketer, Australian SaaS ⭐⭐⭐⭐⭐
