A Convergent TV Platform Built For Agencies

Digital donor acquisition costs are climbing for advocacy organizations. TV reaches donors at scale. Here's how to prove it's working.

Blue State's clients in advocacy, nonprofit, and political campaigns are navigating rising Facebook and Google acquisition costs. TV is the channel that reaches donors and cause supporters at scale -- but most advocacy organizations run TV without attribution connecting airings to donation events, petition signatures, or volunteer actions. Tatari adds that layer: direct CTV buying on Hulu, Peacock, and HBO, biddable linear, and next-day attribution tied to the outcomes your clients actually measure.

Why we sent this

→ Facebook and Google donor acquisition costs have been rising for years. AARP, UNICEF, Sierra Club, and Blue State's advocacy clients need a channel that reaches audiences at scale without paying premium digital CPMs for an audience that's already been retargeted five times.
→ TV reaches that audience. The problem is most advocacy TV campaigns run without attribution connecting airings to donation events, petition signatures, or volunteer signups. That makes TV a hard budget line to justify to a nonprofit board.
→ Tatari's attribution ties every linear and CTV airing to downstream digital actions: site visits, donation page sessions, and conversion events the next morning. TV becomes a measurable acquisition channel, not a brand awareness line item.

What Makes Tatari Different?

Measurable TV for advocacy and nonprofit clients. Every airing connected to donor and cause outcomes.

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

Advocacy clients measure in donations, petition signatures, and volunteer signups. Tatari's attribution ties every TV airing to those outcomes: the Sierra Club spot that aired Sunday and exactly how many donation page visits it drove before midnight. That is the data that justifies a TV budget to a nonprofit board.

Direct media execution

Tatari holds direct relationships with Hulu, Peacock, HBO, and every major linear network. For advocacy clients running cause-based campaigns where brand safety and adjacency context matter, that means guaranteed placement in verified environments. No exchange floor, no programmatic adjacency risk next to content that conflicts with the cause.

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

Tatari gives Blue State biddable access to the linear scatter market and direct CTV buys on Hulu, Peacock, and HBO in one platform. For AARP running national membership campaigns, that means linear and streaming planned together with attribution to membership signups by the next morning. For UNICEF and Sierra Club running cause campaigns, it means the same attribution layer across every airing in every market.

Measurement

Every linear and CTV airing reports the next morning: network, daypart, creative, and the downstream actions that matter for advocacy clients -- donation page visits, petition submissions, and volunteer signups. For a cause campaign with a fixed legislative deadline or fundraising window, that data changes how Josh's team allocates the remaining flight budget.

Agency Spotlight

How DAC made TV measurable and grew client revenue.

DAC is a full-funnel digital media agency that came to Tatari to apply the same measurement discipline to TV that they already ran on digital. They unified linear and CTV in one platform, connected every airing to real downstream outcomes, and drove double-digit revenue growth across their client base. For Blue State, which already runs data-driven digital campaigns for advocacy clients, Tatari extends that rigor to TV.

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