Powered bytechreviewer AI

Last updated: October 2026

Performance snapshot

Tallium Inc. presents a consistently strong performance profile across a broad range of service areas, including mobile app development, custom software, UX/UI design, and AI consulting. The vendor's review base spans nearly a decade, with ratings overwhelmingly at or near the maximum across all evaluated sub-metrics. Recurring strengths include proactive communication, on-time delivery, and tangible business outcomes for clients. No recurring systemic concerns were identified, though isolated minor notes on cost sub-ratings and early-stage design alignment surfaced in a small number of reviews.

Performance breakdown

Technical expertise
Strong

Multiple anchor reviews cite specific technologies including React Native, GraphCMS, Laravel PHP, Swift, Java, Angular.js, AI-driven inventory management, and GPS integration. A third-party code audit for FanLeague passed without issue, and one review documented a 30% increase in user engagement alongside a 20% rise in downloads.

Project management & delivery
Strong

Consistent on-time delivery is documented across more than 20 individual reviews, including a healthcare app delivered within eight weeks and a retail app that went on to win two Bronze Effie Awards. Agile and scrum methodologies, milestone-based planning, and dedicated project managers are frequently referenced as structural delivery strengths.

Communication & collaboration
Strong

Reviewers across multiple industries repeatedly cite proactive, transparent, and multi-channel communication via Slack, Jira, email, and video conferencing. Cross-timezone adaptability is noted explicitly by clients in the US, Sweden, Germany, and Canada, with one client describing communication as 'impeccable' and another praising daily updates throughout development.

Reliability
Strong

A healthcare app was described as 'stable' and well-received by testers, while a gambling platform passed a third-party code review with no issues. One updated review initially rated two stars but was revised upward after the team resolved issues at no extra charge, indicating accountability and remediation reliability.

Client satisfaction & outcomes
Strong

Quantified outcomes include over 50,000 app installations with a 4.8-star store rating, savings of millions of dollars in operational costs for a SaaS client, a 30% increase in user engagement, and two Bronze Effie Awards for a retail mobile app. The vast majority of reviewers across both platforms awarded maximum scores and expressed intent to continue or re-engage the partnership.

Review strength

The assessment is based on 86 reviews drawn from two platforms, providing a high-confidence data set. Reviews span from January 2015 through September 2026, with the majority of reviews published between 2022 and 2026. A significant portion of older reviews, particularly those from 2015 to 2019, predate the three-year recency threshold and should be weighted accordingly, though they are consistent in sentiment with more recent feedback. Review date range: 2015-01-01 - 2026-09-15.
