Tinuiti

Founded in 2004 and grown substantially through acquisitions (including Elite SEM and CPC Strategy), Tinuiti is the largest independent full-funnel performance marketing agency in the United States, managing a reported $3-4 billion in annual digital media spend across more than 1,000 employees. Its client roster is genuinely enterprise-grade and verifiable across multiple independent sources: Rite Aid, Unilever, Sony, E.l.f. Cosmetics, Huda Beauty, Away, Poppi, and Petsmart, among others.

It's built for enterprise and large mid-market brands with substantial, complex media budgets — multiple independent sources report a minimum monthly ad spend requirement reported between $25,000 and $100,000+, depending on channel mix and source, meaning brands below that threshold are unlikely to be a realistic fit at all.

Tinuiti's core differentiator is its proprietary technology platform — referred to as "Mobius" in some sources and "Bliss Point" in others (a naming inconsistency across independent coverage worth confirming directly, possibly reflecting a rebrand or distinct sub-products) — designed to unify media and measurement data across channels into one predictive system. Independent sources specifically credit this technology with helping enterprise clients solve cross-channel budget allocation, a genuinely hard problem for brands running spend across Google, Amazon, Meta, TikTok, and streaming simultaneously.

A specific, worth-flagging gap: Tinuiti's Clutch profile shows essentially no accumulated reviews despite its scale — one archived snapshot shows just a single review on record for an agency managing billions in media spend. This is a genuinely thin independent-verification base relative to the agency's size, similar in kind to gaps found elsewhere in this research (iPullRank, Hawke Media) — worth requesting direct, current client references rather than relying on review-platform aggregates.

• Monthly retainers commonly reported between $10,000 and $25,000+, with a percentage-of-spend fee layered on top that scales as media budget grows — independent sources consistently note that total management costs "can climb quickly" once this layered structure is factored in.
• Minimum monthly ad spend to be considered for a new engagement is reported between $25,000 and $100,000+ depending on source and channel.

Several competitor-published sources (from companies selling AI-driven autonomous ad management as an alternative) argue this traditional layered-fee agency model is increasingly being challenged on cost-effectiveness — worth noting as a live industry debate, though these specific sources carry an obvious commercial interest in that framing and should be read with corresponding skepticism.
