Streaming Audio Advertising Agency — Spotify, Pandora & iHeart Ads
The channel you can’t scroll past.
Headphones in, screen off, sound on. Streaming audio reaches people in the moments every other channel can’t — the commute, the workout, the workday — and we run it as performance media, proven with pixels and holdouts, not downloads.
Share of ear ≠ share of budget.
Americans give audio more than half their listening time. Advertisers give it under three cents of every media dollar. That gap isn’t a problem — it’s the cheapest attention left in the market.
The numbers make the mispricing concrete. On-demand and internet audio is now more than half of US daily listening (Edison Research, Share of Ear, 2025), yet digital audio takes only about 2.8% of US internet ad revenue (IAB/PwC, 2025) — even as that spend grew to $8.4B in 2025, up 10%. When attention and budget are this far out of line, the early, disciplined buyer gets reach at a discount the rest of the market hasn’t priced in yet.

Every hour has a listener.
Drag through the day. Audio doesn’t wait for prime time — it rides the commute, owns the workday, and follows people home. Most digital audio actually peaks at midday, not drive time. Buy the moment, not just the platform.
The daypart curve is not the one most planners assume. Most digital audio — podcasts, streaming, audiobooks — peaks at midday rather than the old drive-time window, and roughly 60% of podcast time happens at home (Edison Share of Ear daypart analysis, 2025). That changes the brief: a lunchtime work-from-home listener is in a different mindset than a 6pm commuter, so the offer, the length, and the call to action should move with the hour, not sit static across the day.
Most digital audio — podcasts, streaming, audiobooks — peaks midday, not drive time; ~60% of podcast time is at home (Edison Share of Ear dayparts, 2025). Curve illustrative.2
The ear is unskippable.
No skip button, no scroll, no muted autoplay — just one voice, sound-on, with your brand’s full share of voice. Try to skip it. You can’t. That’s why audio out-attends video dollar for dollar.
Attention research backs the intuition. Audio drove 10,126 attentive seconds per 1,000 impressions against a 6,501 cross-media norm, and radio ran roughly ten times more efficient than the average online video ad (Dentsu × Lumen, 2023). A Spotify audio ad is non-skippable, sound-on, and holds 100% share of voice for its duration (Spotify product spec) — there is no competing tile, no scroll, and no mute, so the impression you buy is closer to the attention you actually get.

Right platform, right moment.
Each platform owns a different ear, audience, and price. Tap one for the numbers that matter — who’s listening, what it costs, and where it wins. A great audio plan is a mix, not a logo.
The platforms are not interchangeable. Spotify reports 483M ad-supported monthly active users (SEC filing, Q1 2026); iHeart is the #1 US podcast publisher at 63.2M monthly listeners (Podtrac, 2025); and SiriusXM Media sells Pandora and SoundCloud through the AdsWizz exchange, while Amazon Music and podcasts each reach a distinct ear. Match the platform to the audience and the moment — music streaming for broad reach and dayparting, podcasts for trusted endorsement — rather than defaulting to whichever logo is most familiar.

Trust or scale? Yes.
Host-read buys trust, dynamic insertion buys targeting, programmatic buys scale — and the right program blends all three. Drag the mix and watch trust, reach, and cost rebalance in real time.
Each read type sits at a different point on the trust-versus-scale curve. Host-read posts the highest brand recall — about 71% versus 62% for non-host-read (Nielsen) — but costs the most and scales the slowest; dynamic ad insertion, now more than 90% of US podcast ad revenue (IAB, 2024), scales one spot across a catalog with targeting; programmatic adds the broadest, cheapest reach. The blend is the point: open with host-read trust, scale the proven message with DAI, and fill reach programmatically.
Host-read brand recall ~71% vs ~62% for non-host-read (Nielsen); dynamic ad insertion is now over 90% of podcast ad revenue (IAB, 2024) — most host-reads are themselves DAI-served.5

Plan the buy.
Set a budget, pick a format, and dial frequency. Watch impressions, reach, and the number that actually matters — cost per completed listen. Illustrative math; we build the real model on your data.

CPM bands are agency estimates (music ~$15–25, podcast host-read ~$25–40, DAI ~$5–15); audio is non-skippable so completion runs high. Illustrative — RGM analysis.7
Downloads aren’t listens.
Flip the metric. A download is a file request — not a human, not a completion, not a sale. Switch to what a pixel and a holdout actually prove, and the vanity number gives way to revenue.
A download counts a file request, not a verified listen (IAB Podcast Measurement v2.2, 2024). Measure completed listens, pixel conversions, and incremental lift instead. Figures illustrative.8
Stack the evidence.
Audio is the cookieless channel that already works — logged-in and deterministic. Click each way you tie a listen to a result. The more causal the method, the more you can trust the call to scale.
Because most streaming audio is logged-in, attribution is deterministic rather than cookie-dependent — a structural advantage as third-party cookies fade. Rank the methods by how causal they are: pixels tie exposure to on- and off-platform action, promo codes give a directional read but undercount, and a holdout isolates true incremental lift by withholding the campaign from a matched group. Scale on the evidence that survives scrutiny, not on the impression count the platform hands you.
Spotify Ad Analytics and the Spotify Pixel attribute on and off platform; layer promo codes, brand lift, holdout/incrementality, and MMM. Audio runs on first-party logged-in data, not cookies.9
Sound is a brand asset.
A consistent audio logo is the one brand cue that works with the screen off. Toggle it on and watch recall move. Netflix’s “ta-dum,” Intel’s bong, McDonald’s “I’m lovin’ it” — sound you own, free media every time it plays.
Sonic branding compounds in a way creative spend rarely does. A short, owned audio signature attaches to every spot, every platform, and every daypart, so each impression also reinforces the brand — and unlike a logo, it works while the listener is driving, cooking, or exercising with the screen dark. Build it once, use it everywhere, and the recall you pay to create on the first campaign keeps paying out on every one after.
Sonic branding lifted ad recall +17% on radio and +14% on podcasts, and purchase intent +6% / +2% (Audacy × Veritonic, 2023).10

Heard, measured, scaled.
No untargeted reach, no download vanity, no recycled TV spots. A senior team plans the moments, produces sound-on creative, buys the right host-read and programmatic mix, and proves it with pixels and holdouts. Pricing is custom: flat, project, or performance, by fit.
We run streaming audio as a measured system with a profit target, not a reach line on a plan. That means a defensible read on incremental lift before we scale, creative built for the ear rather than a TV cut-down, and a platform mix chosen for the audience and moment instead of the familiar logo. The result is a channel you can hold to a number — cost per completed, attributable listen — rather than a leap of faith dressed up as awareness.
