How we vet every listicle
Every agency featured on Web Tonic passes our 84-point editorial review before a single listicle goes live. This is how we vet each pick:
Verified client outcomes: We require real case studies with measurable KPIs — revenue, ROAS, CPA, retention — tied to the exact category being ranked. No cherry-picked wins, no unverifiable numbers.
Independent reputation: We cross-check Clutch, Google, G2, and Trustpilot ratings, and screen for review-bombing or suspicious patterns. Only operators with a consistent, verifiable track record make the cut.
Beyond that, every listing goes through a quarterly re-audit. We check 84 criteria across 6 pillars to make sure it still holds up — here are some of the checks we run:
A programmatic and CTV advertising agency buys ad space through auctions and private deals rather than from a salesperson, sets the audience, frequency and inventory rules inside a demand-side platform, and places video against streaming TV apps as well as display and audio.
Platform badges proved nothing here. We kept firms whose own site sells programmatic, CTV or media buying as a named service, read the address behind the claim and used each firm's own mark. Eight external firms serving New York survived that pass, eight treat bought media as a core discipline, and none publishes a rate.
What does a programmatic and CTV advertising agency in New York actually deliver?
Audience and inventory decisions, not a rate card. The agency picks the platform, negotiates the deals, sets frequency caps and reports what streaming and display actually delivered. Eight external firms serving New York cleared our check, five publish a local address, and five credit a client.

Frequently Asked Questions
What separates a programmatic agency from the media department of a full-service shop in New York?
The seat and the transparency around it. A programmatic team will tell you which demand-side platform runs the buy, whether the seat is theirs or yours, what the platform fee is against the working media, and which private deals or inventory lists it uses. A media department inside a full-service shop often quotes one blended number, which is fine until you want to compare two flights honestly.
Is CTV just video advertising with a different name?
No, and the difference shows up in measurement. Streaming inventory is bought against households and shows, runs unskippable in most apps and rarely produces a click, so success is read through reach, frequency, incremental site visits or lift studies rather than a click-through rate. Creative rules differ too: safe areas, audio levels and file specs are closer to broadcast than to a social feed.
Which of these firms can I verify before a call?
Five of the eight. Amsive names Nationwide Insurance and Baxter Healthcare, Hunter Digital names Krimson Klover and IBKUL, and Chatter Buzz names 3B Medical and Hallmark Nameplate. The rest name nobody publicly, which is often a contract term rather than evasion, so move the burden to the call: ask for one campaign in your category, the platform it ran on, and what they would change if the budget halved.
Why did two quotes for the same brief differ so much?
Because a programmatic quote hides several different things. Ask what share of the budget reaches inventory after platform and data fees, whether audience data is bought or built from your own lists, who owns the seat and the deal IDs, how many creative sizes or cuts are produced, and whether reporting includes placement-level detail. Those five answers usually rebuild the entire price gap.
Does the agency need to be based in New York?
Rarely, since the auction does not care where the buyer sits. Local presence matters when the buy needs regional inventory relationships, in-person reviews or knowledge of specific retail and transit environments. Five of the eight publish a New York address and the others work the market from elsewhere: Hunter Digital (Port Washington), Chatter Buzz (Orlando, Florida) and Thrive Internet Marketing Agency (Arlington, Texas). Judge the seat, the reporting and the named contact before you judge the postcode.
Choosing a Programmatic and CTV Partner in New York
Five of the eight external firms here publish a New York address, so geography will not shorten this list for you. What separates them is whether the buy is explained platform by platform or handed over as one blended figure.
Five credit a client you can check, and not one publishes a fee, so every number on this page is quoted against scope. Settle seat ownership, data costs and placement-level reporting before you compare two proposals.
The clearest signal of a serious buyer is a shorter inventory list, not a longer one. Ask which apps or publishers were dropped last quarter, what frequency cap the plan assumes, and which single figure should move first if the flight is working.
Whichever way the brief lands, keep the buy, the creative and the measurement answerable to one owner, because a confident dashboard on inventory nobody audited mostly buys the same impression twice. If you would rather have the media plan, the paid social running beside it and the measurement owned by one team, read our latest analysis or see how we work in New York.
