AI Overview

Powered bytechreviewer AI
This company performance overview is based on AI analysis of 82 client reviews across 2 different review platforms. Read more about our methodology.
Last updated: April 2026

Performance snapshot

Tallium Inc. presents a consistently high-performing profile across a broad portfolio spanning mobile app development, custom software, UX/UI design, web development, and AI consulting. The overwhelming majority of ratings across both reviewed platforms are perfect scores, with anchor reviews containing specific metrics such as 50,000+ app installations, a 4.8-star App Store rating, two Bronze Effie Awards, millions of dollars in operational savings, and an 8-week app launch. The pattern of ratings is almost uniformly Strong across all five categories, with no recurring negative trends or structural weaknesses identified. One notable concern is that a small subset of early reviews (2016–2019) and one updated review reflecting an initially poor experience suggest isolated historical inconsistencies, though these were resolved and do not represent a current pattern.
