Joshane Kelsy
I make AI useful, not just impressive.
12+ years building products at scale. Mentoring the next generation of PMs.
About
I'm a Group Product Manager at Rakuten, where I lead AI and data products that serve millions of users. Before that, I built consumer and fintech products at Grab, Zomato, and Truecaller across Southeast Asia.
Over 12+ years, I've gone from zero-to-one builds to scaling platforms across 8 countries. I care deeply about making AI genuinely useful, and mentoring the next wave of product leaders along the way.
Outside of work, I'm a Top 1% PM mentor on Topmate, an occasional speaker, and an advocate for emotionally intelligent teams.
What I Believe
- The best products come from emotionally intelligent teams, not just technically excellent ones.
- Ship the proof, then sell the vision.
- Mentor the person, not just the resume.
