Opal Tech Stack

Mobile focus app helping millions reduce phone distractions

Mobile Computing Software Products New York City, NY 11–50 employees Privately Held

Opal is a consumer mobile app (iOS + Android) with 10M+ active users focused on reducing phone distraction and aligning device use with well-being. The company is mid-scale, but the hiring profile — 11 engineers split across Android and iOS, minimal hiring velocity, and a lean marketing/education team — combined with active projects around Android v2, building out the Android team from scratch, and expanding to new demographics suggests a deliberate, product-first phase of growth rather than aggressive scaling.
