The best programmatic advertising agencies

Programmatic is no longer a channel you add to a media plan. It is the way most digital display, video, audio and out-of-home inventory is now transacted, which means picking a “programmatic agency” is not one decision but three bundled together: which demand-side platforms the agency can genuinely operate, how transparent its supply path and fee structure are, and whether it can measure incrementality rather than last-click. Get those three right and the channel choice largely takes care of itself.

This guide is an independent shortlist of programmatic advertising agencies worth considering in 2026, along with what the media itself tends to cost and how to interrogate a proposal. We publish benchmark data on what advertising costs around the world, so our interest is in helping you compare like for like, not in steering you toward any one firm. No agency paid for inclusion or position, and every profile below is drawn from the firm’s own published material.

Why programmatic is a distinct buying decision

Most agency roundups treat programmatic as a synonym for display. It is not, and three structural features make it a different hire from a general paid-media shop.

The technology sits between you and the inventory. In search and social you buy inside a single platform owned by the seller. In programmatic your budget passes through a demand-side platform, often an exchange or supply-side platform, sometimes a data provider and a verification vendor, each taking a slice before a dollar becomes an impression. That chain is where money leaks, and it is the reason fee transparency matters more here than in any other channel.

Platform access is a real constraint. Agencies build around specific DSPs, and those commitments shape what they can buy well. The market splits along a fairly clear line: Display and Video 360 is the natural home for advertisers already deep in the Google Marketing Platform and Google Cloud stack, The Trade Desk is the independent alternative for the open internet, and Amazon DSP has become a third pole as retail media matured. An agency that lists nine platform badges but runs one seat in practice is a different proposition from one built around a single platform it knows intimately.

The channel scope is much wider than display. Modern programmatic practices buy converged TV across linear, streaming and over-the-top, converged audio across podcasts, streaming and radio, native, digital out-of-home, display and retail media networks. That list, taken from Wpromote’s published programmatic practice, is a reasonable checklist to hold any shortlisted agency against. Very few can do all of it equally well, and you should know which parts your candidate is actually strong in.

What programmatic advertising actually costs

The most useful thing an independent publisher can add to an agency roundup, and the thing agency-written lists almost never include honestly, is what the media itself costs. An agency’s fee is only part of the budget. The auction and the technology stack are the rest.

There are three cost layers to separate before you compare any two proposals:

• The agency fee: a retainer, a percentage of media spend, or a performance or hybrid model. Each creates a different incentive and each looks cheapest under a different spend scenario.
• The technology fee: the DSP take rate, plus data segment fees, verification, and any proprietary platform charge. This is frequently bundled into a single “managed programmatic” number and it deserves to be unbundled.
• The media cost: the CPMs you actually clear in the auction, which vary enormously by format. Connected TV, premium video, audio, display and digital out-of-home are not remotely the same price for the same reach.

The ratio that matters is working media: the share of your total budget that ends up buying an impression rather than paying for the machinery that delivered it. If an agency cannot tell you what it takes as margin, what it takes as tech fee, and how much of your budget reaches working media, that single question will tell you more than the rest of the pitch.

The practical takeaway: go into the conversation with a rough sense of what your formats cost in-market, so you can tell whether a proposed CPM is competitive, whether a proposed budget can buy the reach being promised, and whether the agency’s fee is a sensible fraction of the total.

How to choose a programmatic advertising agency

Once you have a budget in mind, the choice comes down to fit. The right agency for a mid-market brand buying CTV and audio is rarely the right one for an enterprise running global retail media, and neither is right for a regulated category locked out of mainstream platforms.

Work through four things, in order:

1. Platform fit, verified. Establish which DSP the agency proposes and why, and check that the recommendation follows your data rather than their convenience. If your first-party data, analytics and cloud warehouse are Google-based, a Google Marketing Platform specialist removes a lot of integration work. If you need the open internet plus independence from a walled garden, The Trade Desk route makes more sense. If retail media is where your growth is, Amazon DSP capability is not optional. Ask for named certifications and partner tiers, then ask who holds them.

2. Supply path and fee transparency. Ask for the full chain: which exchanges, what the DSP take rate is, whether the agency holds direct supply-side deals, and what it does about made-for-advertising inventory. Some agencies compete explicitly on disclosure, others on preferential rates they have negotiated on premium inventory. Both are legitimate, but they are different bargains and you should know which one you are signing.

3. Measurement capability. Programmatic is the channel where last-click attribution fails hardest, because much of its value is upper funnel. Ask whether the agency runs incrementality tests, media mix modelling, or holdout groups, and ask to see a real example rather than a capability slide.

4. The operating model. Managed service, self-serve seat, or white-label. Several agencies offer all three, and the right answer depends on whether you have in-house capacity. Also ask the unglamorous questions: who runs your account day to day, how many accounts they carry, and whether you own the seat, the data and the audience segments if you leave.

The agencies

Our selection criteria are stated up front: each agency has a genuine programmatic practice described in public detail on its own site, a verifiable operating record including named platforms, tools or client work, and enough published specificity that a buyer can check the claims. This is a curated shortlist rather than an exhaustive directory. We excluded ad-tech platforms and DSPs that are not agencies, directory listings, and several well-known agencies whose public material described paid media generically with no programmatic, DSP or CTV detail we could verify. Firms are listed by fit, not by fee, and inclusion is never paid.

1. Goodway Group

Goodway Group is an independent media and growth partner focused on commerce, retail and CPG brands, describing itself as bringing “Commerce, Connection and Consulting together as one.” On its Connected Commerce page the agency states it runs search, social, retail media and programmatic in sync as one connected system rather than as separate channel teams, supported by its proprietary Connected Commerce OS, GOES. The company traces its history to 1929, when it was founded as Goodway Printing Company by Milton Wolk, and remains an independently owned, fourth-generation business, with Paul Frampton as CEO and David Wolk as executive chairman. It cites awards including the Modern Retail Awards, AdExchanger commerce and retail media awards, Digiday Retail and The Drum Awards for commerce. Best fit: retail, CPG and commerce brands that need programmatic wired into retail media and in-store outcomes.

2. Tinuiti

Tinuiti describes itself as the largest independent full-funnel marketing agency “across the media that matters most,” spanning search, streaming and retail media, with media and measurement under one roof. Its activation is powered by the patented Bliss Point by Tinuiti technology, acquired when the agency bought streaming-media buyer Bliss Point Media, alongside Amazon operations specialist Ortega Group. The business began as Elite SEM, a search-led performance firm founded in New York City, and later rebranded following a series of social, email and Amazon acquisitions. It states it was the first independent performance marketing firm to win Microsoft’s Global Agency of the Year award, and it has also won a Google Premier Partner of the Year award for International Growth. Best fit: brands wanting streaming, CTV and retail media bought and measured alongside search and social by one independent team.

3. Wpromote

Wpromote runs a dedicated programmatic practice covering converged TV (linear, streaming and over-the-top), converged audio (podcasts, streaming and radio), native, digital out-of-home, display and retail media networks. The agency says it holds direct partnerships with DSPs and SSPs that give clients pre-negotiated rates on premium inventory, and that campaign data flows into Polaris IQ, its AI-native marketing data platform used for creative audits, media mix modelling and anomaly detection. A published case study describes a multi-touch programmatic plan for Anytime Fitness using upper-funnel video, CTV and premium display across platforms including Spotify, ESPN and Twitch. Best fit: advertisers running multi-format programmatic across CTV, audio, DOOH and display who want it unified with search and social reporting.

PMG calls itself a global independent platform company, operating 13 global hub offices with more than 1,000 team members, and reports 90 percent client retention. Its work is built around Alli, PMG’s proprietary marketing operating system, spanning what it labels Intelligence Core, Marketing Orchestration, Signal-led Creativity, Momentum Lab and Growth Blueprinting. On the programmatic side PMG lists The Trade Desk Premier Partner status, with priority access to alphas and betas plus data analytics integrations, and Simpli.fi for premium programmatic executions via Alli, alongside Google Premier, Amazon Advanced, Meta, TikTok, Snap, Reddit, LinkedIn and Microsoft Elite partnerships. It also names data partners including Blis for privacy-first location intelligence and LiftLab for incrementality modelling. Best fit: large global brands that want Trade Desk-grade programmatic run inside a single measured omnichannel plan.

Kepler Group is headquartered in New York and says it has grown since 2012 from six people to over 600 employees across 10 global offices, joining the kyu collective alongside IDEO, Sid Lee and SYPartners, and merging with programmatic specialist Infectious Media to create a global offering. Its Media and CRM practice plans and executes audience-driven campaigns across organic search, paid digital, advanced TV and CRM, and the agency commits to “100% transparency on every penny spent and tactic deployed.” Activation is supported by Kip, the Kepler Intelligence Platform, which has been recognised by AdExchanger for Best Commerce Media Technology and by Martech for Best Marketing Performance Management Solution. Kepler has also been named Digiday’s Most Innovative Media Agency for two consecutive years.

6. Adswerve

Adswerve positions itself as a predictive marketing consultancy built around the Google and Adobe stacks, offering data and digital media consulting, martech licensing and training, measurement and insights, and media strategy and activation. It states it is the number one Google Marketing Partner in the US with more than 170 GMP certifications, and that it was named Adobe Solution Partner of the Year for a third consecutive year, working across Google Marketing Platform, Google Cloud and Adobe Experience Platform. The firm reports 250+ experts, 800+ brands and agencies served and $1B in ad spend managed, with client work published for Alaska Airlines and the World Surf League.

It has built proprietary tools including a real-time inventory scoring engine that filters low-quality and made-for-advertising placements without raising CPMs, a creative intelligence scorer, and the Audience Intent Meter for intent-based budget shifts. Published case studies include Moderna’s #SpikevaxPartner creator campaign, reported at 503 million impressions and 72,000 site visits, Bread & Butter Wines with a full-funnel CTV, influencer and Instacart activation, and Humane World for Animals, which it reports drove over $200,000 in donations.

The company reports $300M+ in revenue generated and 200+ brands served. Best fit: regulated-category advertisers in cannabis, alcohol, gaming or politics who are locked out of mainstream ad platforms.

How to measure programmatic ROI

Programmatic is the channel most likely to be measured badly, because so much of its value lands before the click. Agree the metrics before the first impression serves.

Define the conversion that matters, then define the counterfactual. A qualified lead, a purchase, or a return-on-ad-spend target is the scoreboard, but for upper-funnel programmatic the more important question is what would have happened without the spend. Impressions, viewability and completion rates are delivery quality checks, not results.

Insist on real attribution, not last click. With third-party cookies gone and signal loss now the norm, credible measurement means server-side tracking, first-party data, and, at meaningful budgets, incrementality testing or media mix modelling. Several agencies on this list name specific partners or in-house tooling for exactly this, and that is a fair thing to hold them to.

Audit the supply path as part of ROI. A campaign can hit its CPA and still be wasting a large share of budget on low-quality inventory or intermediary fees. Ask for a periodic supply-path report showing where impressions were bought, at what cost, and how much was filtered out. An agency that treats this as routine is telling you something useful.

Judge over the right horizon. Delivery signal arrives in days, business outcomes in two to three months. Any agency promising immediate, clean programmatic ROI is selling rather than measuring.

What’s changing in 2026

Three shifts are reshaping programmatic buying, and each is worth raising with any agency you shortlist.

Supply-chain transparency has become the live differentiator. The market has split between agencies that compete on disclosure and agencies that compete on preferential access. Some publish explicit commitments to account for every penny spent, some advertise pre-negotiated rates on premium inventory through direct DSP and SSP relationships, and some have built tooling to score inventory quality and strip out made-for-advertising placements in real time. Whichever model you prefer, the era of accepting an undifferentiated “managed programmatic” line item is over.

Retail media and connected TV are absorbing the budget. Retail media networks now sit inside programmatic plans rather than beside them, which is why agencies are foregrounding Amazon DSP capability and commerce-specific operating systems. CTV is where both spend and scrutiny are concentrating, and the emerging best practice is to build buys around audience rather than around individual apps or publishers.

Regulated categories have become their own market. Cannabis, alcohol, gaming, political and sexual-wellness advertisers are excluded from most mainstream self-serve platforms, and specialists exist because compliance, meaning age-gating, creative restrictions and state-by-state policy, has to be enforced at the inventory level rather than bolted on afterwards. If you are in one of these categories, a generalist shortlist will waste your time.

How to shortlist from here

Use this list as a starting point, not a verdict. Shortlist two or three agencies whose platform access and format strengths match what you actually need to buy, take them through the questions above, and press hardest on the fee and supply-path answers, because that is where the difference between two similar-looking proposals usually hides. Above all, go in knowing what your formats should cost in-market, so you can tell a realistic plan from an optimistic one. That last part is what we are here for.
