How to advertise on Last Podcast On The Left: what it costs, who buys, and how to book

Host-read inventory on Last Podcast On The Left is sold on a quoted basis, through the hosts' own Last Podcast Network with distribution and ad sales running through SiriusXM and Stitcher, not off a public rate card. Spotsnow attributes roughly 42 to 49 host-read ads and over $1M in estimated spend to a single advertiser, Squarespace, the top buyer on the feed. Spotsnow data shows the show's direct-response ad share sits well into the 90s, so if you're a brand weighing this show, you're buying coded attribution, not a branding halo. Spotsnow estimates all of this from tracked advertiser activity, not audience surveys. See the full profile for Last Podcast On The Left on Spotsnow.

Why Last Podcast On The Left is built for host-read direct response

Marcus Parks, Henry Zebrowski, and Ed Larson host it, with Parks as the show's primary researcher, a former college radio station manager, and co-author of the New York Times bestseller The Last Book on the Left. Spotsnow files the show under information technology & services for its top advertiser mix, though the feed itself is true crime and comedy.

That direct-response share sitting in the 90s is the number that matters. It means brands here run codes, vanity URLs, and promo readouts they can track. Spotsnow estimates the show reaches roughly 1.07 million listeners, and that reach is an estimate, not an audited count. The audience skews male, lands mostly in the young to mid-career range, sits middle to upper-middle income, and concentrates in the US with real tails in Canada and the UK.

The format is the argument. The trio runs long, digressive, unscripted banter, so when a read lands it lands mid-conversation and the listener is still there. A host endorsement borrows exactly that sustained attention. The Apple average of 4.6 stars across roughly 46,000 to 54,000 ratings, plus roughly 518,000 Instagram followers and roughly 216,000 YouTube subscribers, backs the feed as an endorsement channel that reaches well beyond the audio player and onto Twitch, TikTok, live tours, and a bestselling book.

Who is advertising on Last Podcast On The Left

The roster runs deep, with over 170 brands tracked in the last three months, weighted toward tech, fintech, telecom, home security, and DTC. Recognizable names in the mix: Squarespace, Chime, Mint Mobile, SimpliSafe, and BetterHelp.

The anchor advertisers, broken down

Squarespace

Squarespace sells website building and hosting for creators and small businesses. Spotsnow attributes roughly 42 to 49 ads and over $1M in estimated spend, classified almost entirely as direct-response. It's the top spender, and it fits because this is a build-your-own crowd: touring comedians, merch sellers, and side-project types who need a site up fast.

Mint Mobile

Mint Mobile sells budget prepaid wireless on the T-Mobile network. Spotsnow attributes roughly 47 to 55 ads and over $900K in estimated spend, classified as fully direct-response. Its Ryan Reynolds-era comedic voice matches the show's tone, and a price-conscious young audience is exactly who switches carriers on a promo code.

Chime

Chime is a fee-light neobank aimed at everyday Americans. Spotsnow attributes roughly 18 to 21 ads and over $700K in estimated spend, mostly direct-response. Its checking and credit-builder pitch speaks directly to a younger, middle-income listener managing cash flow between paychecks.

The outlier: Progressive

Progressive runs a meaningful presence here, but as produced brand-awareness spots rather than host-read direct response. It's proof a different objective can work on this feed, even if it isn't the coded read most buyers come for.

Why information technology and DTC brands cluster here

The tie is authority plus mindset. Parks does the research himself, and that grounding force gives the hosts credibility that transfers to a read. The audience is young, mostly male, and comfortable acting on a URL or a code the second it's spoken, which is why a website builder, a prepaid carrier, and a neobank all keep buying. This isn't a soft awareness feed where a logo sits in the background. Brands come back because the read converts, and they can see it in their attribution. The comedy holds the listener through the break, and the endorsement rides that attention straight to a signup.

How your ad could sound

Here's a real host-read from the feed. Listen to how the offer lands after a full stretch of unscripted banter.

What works: the framing is personal and unscripted. The host drops an actual piece of advice, that "it's not how much you put in the market, it's how long you are in the market for," then hands to a clean coded offer, "sign up now and Acorns will boost your new account with a $5 bonus investment." That mix of a genuine opinion and a concrete incentive is what a host-read is for.

What to tighten: the handoff runs loose. The bit before the offer is long, and the promo lands late, so the call to action arrives without urgency. If you're briefing a read for this show, keep the personality but move the code up and give it a reason to act now.

What makes a show like this convert

1. The format holds attention. Long unscripted banter keeps listeners present through the break, so a host read lands instead of getting skipped.
2. Host credibility transfers. Parks researches the show himself, and that authority makes an endorsement read like a recommendation, not a spot.
3. The audience acts on codes. A young, mostly male, middle-income US audience is the profile that redeems a URL or promo the moment it's spoken.
4. Repeat buying proves the math. Squarespace at roughly 42 to 49 ads doesn't renew that deep unless the reads pay back.

Last Podcast On The Left in a nutshell

The audience is a large, mostly male, young to mid-career US following that trusts the hosts and follows them across platforms. The brands already buying, Squarespace, Mint Mobile, and Chime, run coded host-read endorsements, not produced background spots. The show is quoted per campaign through the Last Podcast Network and SiriusXM rather than off a rate card. If your goal is trackable direct response, this is a fit; if you only want soft reach, look elsewhere.
