A Convergent TV Platform Built For Agencies

Arena runs CTV across 6 DSPs and linear the old-school way. Here's what one platform gets your clients.

Arena runs up to 2,000 campaigns a season across StackAdapt, Yahoo, Beeswax, ClearLine, and Viant for CTV, with linear placed separately through manual workflows. Tatari consolidates CTV and linear into one platform, buys CTV direct from publishers at your $5-$15 CPM target, and gives every campaign next-day attribution across both channels.

Why we sent this
Arena manages campaigns for political clients, super PACs, FanDuel, DraftKings, and advocacy organizations across six DSPs and a separate manual linear workflow. Monday mornings mean emailing every vendor individually. Linear creative approvals require documentation chains with premium publishers. The digital team has to manually emulate the linear messaging sequence after the fact because the two channels do not talk to each other. DAC ran the same fragmented workflow and used Tatari to unify linear and CTV into one platform with shared attribution. Arena is heading into busy season. The time to fix the workflow is before the volume peaks, not after.
What Makes Tatari Different?
One platform for Arena's linear and CTV. Before busy season starts.
Purpose-built for TV
Traditional DSPs were built for display and online video. They were never designed for how TV inventory actually works. Tatari was. Linear, streaming, and online video in one platform, with buying logic built around TV's unique clearance, pricing, and audience dynamics.
Measure real outcomes
Arena's campaigns track outcomes at the voter and donor level. Tatari's closed-loop attribution ties every TV airing to those same outcome signals: site visits, list matches, and conversion events tied to the specific spot, network, and creative that aired. For advocacy and political clients, that is the data that justifies the TV buy in the post-campaign report.
Direct media execution
Tatari buys CTV direct from Hulu, Peacock, ESPN, and other premium publishers, bypassing StackAdapt and the other DSP layers Arena currently uses for streaming. That removes the supply path markup, hits the $5-$15 CPM range Arena targets on major publishers, and gives full placement transparency on every impression. No aggregated DSP delivery reports.

Media Buying

Tatari can replace the multi-DSP CTV workflow Arena runs today with a single direct-buy platform that hits the same publishers at lower CPMs. Linear sits alongside CTV in the same interface, so the digital team stops manually emulating the linear messaging sequence. AI-powered planning tools predict clearance and performance before the buy is submitted, and weekly creative swaps are built into the workflow rather than managed through email chains.

Measurement

Every linear spot reports the next morning: network, daypart, creative, and exactly how many site visits or conversion events it drove. Arena's current linear workflow produces no next-day data. The digital team finds out what aired after the fact and manually adjusts the CTV sequence to match. Tatari's closed-loop measurement ties both channels to the same outcome layer so Molly gets one unified report across every campaign, not separate linear and CTV decks to reconcile before client calls.

Agency Spotlight
How DAC unified linear and streaming into one platform and proved TV outcomes to clients.

DAC is a full-funnel digital media agency running campaigns across linear and streaming for multiple clients simultaneously. They came to Tatari with the same operational problem Arena has: linear and CTV managed separately, no unified attribution, manual workflows to reconcile reporting across channels. Tatari consolidated both into one platform with a single attribution layer across every airing.

"Tatari has modernized TV and made it measurable, which gives us the confidence to recommend TV to our clients."

Felicia DelVecchio, VP of Media, DAC

Measurement that sticks
DAC used Tatari's unified cross-channel report to show clients exactly what linear and streaming drove together. One report replaced two separate platform decks and gave clients a clear picture of total TV outcomes.
New revenue
A full TV service line
Arena already runs CTV at scale. Tatari adds linear in the same platform and removes the DSP markup from the CTV buy, so Molly can show any political or advocacy client a unified attribution report instead of reconciling separate channel decks.
Premium access
Inventory beyond programmatic
Secure Hulu, Peacock, and ESPN inventory direct, plus linear placements on cable news and broadcast, all in one platform. No Monday morning vendor emails. No manual creative sequencing between channels.
