How to advertise on Stuff To Blow Your Mind: what it costs, who buys, and how to book

Stuff To Blow Your Mind sells its host-read inventory on a quoted basis, not a rate card, with each buy priced per campaign rather than off a fixed sheet. The show runs almost entirely on direct response: Spotsnow ad-context data shows more than four in five ads read as coded, trackable spots. Its top spender, Wix, has run roughly 110 to 128 ads on the feed, an anchor-level commitment that tells you more than any headline number could. For a buyer weighing the show, that mix says this is a conversion feed, not a branding play. Spotsnow estimates all of this from tracked advertiser activity, not audience surveys.

The full show profile lives on Stuff To Blow Your Mind, where the roster and spend estimates below are drawn from.

Why Stuff To Blow Your Mind is built for host-read direct response

Robert Lamb and Joe McCormick host, both longtime science writers and producers who built the show out of the old HowStuffWorks stable. It sits in information technology & services, the category that classifies its three biggest anchors, though the show itself is a science feed.

Spotsnow attributes more than four in five ads here to direct response. That matters because DR lives on codes, tracked URLs, and clean attribution, and this format delivers all three. Reach is estimated at roughly 110,000 listeners per Spotsnow, always an estimate, never an audited count.

The reason the format works isn't audience scale, it's how the show holds attention. Lamb and McCormick walk through a single idea slowly, building curiosity across a long episode, so when the read arrives the listener is already leaning in. A host-read borrows that trust. The endorsement lands inside the same voice that just explained a cosmic mystery, and the offer rides the attention the hosts already earned.

On engagement proof, the show's influence is concentrated in the feed rather than spread across social platforms. Spotsnow social stats show an Instagram following under 1,000, which means the listening relationship, not a cross-platform presence, is where the value sits. Advertisers who repeat here are buying that in-ear trust directly.

Who is advertising on Stuff To Blow Your Mind

The roster leans toward tech, retail, and financial brands that want measurable action, and Spotsnow tracked roughly 239 to 278 brands across the recent window. Recognizable names include Audible, T-Mobile, Walmart, State Farm, and Virgin Voyages.

The anchor advertisers, broken down

Wix

Wix sells a website-building platform for individuals and small businesses. Spotsnow estimates total spend on the show at over $250K, across roughly 110 to 128 ads, all direct-response. A build-your-own-site product fits an audience of curious, higher-income listeners who are the exact people starting a side project or a small venture.

Autotrader

Autotrader runs the online marketplace for buying and selling cars. Spotsnow estimates total spend at over $100K, across roughly 55 to 64 ads, mostly direct-response with a small awareness slice. Working-age listeners in their prime earning years are a natural fit for a considered purchase like a car.

Audible

Audible sells audiobooks and spoken-word subscriptions. Spotsnow estimates total spend at over $20K, across roughly 25 to 29 ads, all direct-response. An audience that chooses to spend hours listening to ideas is close to pre-qualified for a spoken-word habit.

The awareness outlier

Not every buy here is coded. Autotrader carries a small awareness slice alongside its trackable reads, which shows a brand can lean on association and top-of-mind lift on this feed without a promo code doing the heavy lifting. It's the exception that proves the show can serve more than one objective.

All spend figures are Spotsnow estimates.

Why information technology & services brands cluster here

The pattern isn't an accident. A science feed hosted by two writers who explain things for a living attracts people who like understanding how something works before they commit to it, and that's the same mindset a software trial or a car marketplace wants to meet. The hosts have spent years earning the benefit of the doubt, so when they hand off to a website builder or a subscription, the listener treats it as a recommendation, not an interruption. Add a higher-income, US-heavy base in its prime working years, and you get an audience that can act on an offer and has a reason to. That combination, authority plus intent plus disposable income, is why tech and considered-purchase brands keep buying the same slot.

How your ad could sound

Here's a real produced block that recently ran on the feed, stacking three advertisers back to back.

The Chase spot in this block does one thing well: it opens with a scene, a kid asking to buy a drum kit with an after-school job, which is a warmer hook than a feature list. The ChatGPT read has a clear promise, that it can "move from a goal to polished work faster." What's missing is the thing that makes this show convert. There's no host handoff and no spoken promo code, so nothing ties the listener to a measurable action in the moment.

That's the contrast to build against. A host-read on this feed should let Lamb or McCormick frame the product in their own words, land one clean offer, and say a code out loud twice so it sticks. Keep the CTA specific, put urgency behind it, and don't bury the code under a scene. View what a great sample ad looks like here.

What makes a show like this convert

1. The format earns attention. Long, single-idea episodes keep listeners leaning in, so the read lands inside a moment of focus rather than a scroll-by.
2. Host credibility transfers. Lamb and McCormick have spent years explaining things carefully, and that trust carries into the endorsement.
3. The audience can act. A higher-income, US-heavy base in its working years has both the reason and the means to follow an offer.
4. Buyers come back. Wix alone has run roughly 110 to 128 ads on the show, and repeat buying at that depth is the clearest sign the math works.

Stuff To Blow Your Mind in a nutshell

The audience skews male, higher-income, and concentrated in the US in its prime working years, the kind of listener who researches before buying. The brands already there, Wix, Autotrader, and Audible among them, buy mostly host-read direct response, and Wix's spend leads the pack. The show sells on a quoted, per-campaign basis rather than a public rate card. If you're chasing measurable conversions with codes and tracked links, this feed fits; if you only want reach, look elsewhere.
