Zhexi Feng
Co-founder & CTO
Zhexi builds the app and the technology behind it. He focuses on making the experience feel steady, safe, and respectful—so it stays gentle even as it grows.
What we're building
Rainbow Petopia is a private-first, returnable memorial world for pet parents. Users can save memories, write letters, and receive gentle, bounded AI replies—without denying loss.
Stage
Prototype iOS build + recorded demo. Closed pilot list confirmed; invite-only pilot launching next.
Not revival / Not therapy
We don't claim pet revival or spiritual communication. This is a memorial/reflection experience, not therapy or medical advice.
Where love continues, memories grow
Rainbow Petopia is a gentle world you can return to when grief resurfaces—private by default, and always at your pace.

Kuan Chang
Co-founder & COO
Kuan helps turn care into real progress. He listens closely to users across the US and China, builds the early community, and makes sure what we create is something people can truly come back to.
