A Convergent TV Platform Built For Agencies

Prophet takes clients from brand insight to media execution. TV attribution closes the loop between the two.

Prophet's campaigns practice runs from insight to execution without handoffs. For clients like T-Mobile, CVS, and Marriott -- all heavy TV spenders -- that execution includes linear and CTV buys. What's missing is the attribution layer connecting those airings to the business outcomes Prophet's strategy promised: customer acquisitions, pharmacy visits, hotel bookings. Tatari closes that loop.

Why we sent this
  • → Prophet's own campaigns page says accountability has grown like never before. TV is the channel where that accountability is hardest to prove -- airings run, reach is reported, and the link to business outcomes is assumed rather than measured. Tatari is the tool that makes the accountability real.
  • → T-Mobile, CVS, and Marriott are buying TV through holding company AORs at programmatic CPMs. Tatari buys the same Hulu, Peacock, and HBO inventory direct at $10-13 versus $25-30 through a DSP stack. When Prophet's campaigns practice recommends TV for a client, the CPM advantage and attribution are built in -- not sourced separately.
  • → T-Mobile measures in customer acquisitions. CVS measures in pharmacy visits and retail conversions. Marriott measures in booking sessions. All three are running TV. Tatari connects each airing to those specific outcomes -- the morning after it airs, by network and daypart.
What Makes Tatari Different?
Attribution that connects Prophet's TV execution to the business outcome the strategy promised.
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
A T-Mobile spot that airs Sunday drives Monday wireless plan sessions. A Marriott airing during travel programming drives Tuesday hotel searches. That data is in the dashboard by 8am -- before the client calls to ask what last week's TV spend drove.
Direct media execution
Tatari holds direct publisher relationships with Hulu, Peacock, HBO, and every major linear network. For T-Mobile and CVS running national campaigns, that means guaranteed placement without exchange adjacency risk -- and CPMs that reflect actual publisher cost, not programmatic markup. Prophet's media plan costs less and proves more.
Our Platform and Services
Linear Biddable buying motion

Biddable scatter market access at real-time pricing. Rates are automatically negotiated down before the buy clears. No rep back-and-forth, no delivery surprises.

Measurement Next-day reporting

Next-day spot-level reporting on every linear airing. Publisher-level placement data on every CTV impression. One dashboard, not two separate reports to reconcile.

Media Buying

Prophet stays the strategy, creative, and media planning lead. Tatari handles the direct TV and CTV execution layer -- buying, optimization, and attribution. For Kathe's team managing full-funnel campaigns, that means one attribution report covering both digital and TV performance, not separate decks to reconcile at the client review.

Measurement

Every linear and CTV airing reports the next morning: network, daypart, creative, and the business outcome it drove. Kathe's team walks into the T-Mobile or CVS review with attribution data -- customer acquisition events, site visits, retail activity -- not just reach and frequency. That's the accountability Prophet promises.

Agency Spotlight
How DAC made TV measurable and grew client revenue.

DAC came to Tatari with an established media practice but no TV-specific attribution. Adding Tatari connected every airing to real downstream outcomes and drove double-digit revenue growth.

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

Client retention
Measurement that sticks
When DAC could prove what TV drove, clients expanded their TV budgets. Prophet's clients are already spending on TV -- attribution turns those campaigns from brand investments into proven business drivers that grow the scope of each engagement.
New revenue
A full TV service line
Prophet's campaigns practice promises no handoffs from strategy to execution. TV attribution is the proof that the execution delivered what the strategy promised. When T-Mobile asks what the campaign drove, Kathe's team has a specific answer before the question is asked.
Premium access
Inventory beyond programmatic
T-Mobile and CVS are the entry points. Marriott, Samsung, and the full campaigns roster follow. One MSA covers every Prophet client that runs TV -- not a separate negotiation per engagement.
