YC Summer 2026 (S26) founder

Maryanne Alhallak

Founder of Lumeria, Oura Ring for Skin

Company

Maryanne Alhallak is listed as a founder of Lumeria. The Lumoscope is a multispectral camera that clips onto your phone and scans your skin at home with the same light used in clinics. You see what a mirror can't: a breakout days before it surfaces, and wrinkles changing over time. Our software then reads that history, connects flare-ups to causes you'd never suspect, and matches products to what your own data shows works.
