#156 — Podcast ads for startups

Yes, but only if you approach them as a disciplined test channel rather than a silver bullet. As networks like Acast report 41% sales growth fueled by brands like Capital One and Coca-Cola, CPMs and competition on top shows have risen, making it harder for early-stage companies to stand out purely on host-read endorsements. For founders, podcast ads can still work if you focus on tightly matched audiences, smaller shows on par with your brand’s size, and clear measurement windows instead of chasing the biggest, buzziest podcasts.

Founders should think in terms of a portfolio test, not a single show buy, and be prepared to spend at least low five figures to learn anything meaningful. Asset, a butt-care startup, spent about $60,000 testing multiple shows, with most of the budget on a single large LGBTQ-focused podcast, and ultimately learned that its money was better spent on performance channels in the short term. A more prudent approach is to spread a smaller budget across 3–5 shows with enough frequency to measure impact, and to set a clear cutoff point where you’ll either scale or pause the channel.

For most startups, smaller and mid-sized shows are a better starting point than flagship celebrity podcasts. Asset’s ad on "The Bald and the Beautiful" followed major advertisers like Wayfair, Hungryroot, and BetterHelp, and underperformed despite a strong demographic fit, while smaller shows like "Very Delta with Delta Work" drove the highest traffic and conversions for the brand. Niche shows tend to have less ad clutter, more engaged communities, and hosts who are more willing to build a relationship with the brand, all of which can significantly improve ROI.

Start with your customer’s real listening habits, not just obvious category shows. Little Spoon, a kids’ food brand, initially aimed at millennial parents and discovered those parents spent time across lifestyle shows like "The Toast," true crime like "Morbid," and news podcasts—not just parenting content—so the company spread partnerships across that full genre spectrum. Combine genre insights like Triton Digital’s finding that true crime listeners over-index with big-box retail shoppers with your own customer research to match shows to both mindset and purchase behavior.

Creative that feels native to the show and anchored in specific pain points tends to perform best. Little Spoon increased emotional connection by tailoring talking points to each program—for example, framing the product as a solution to "mealtime drama" on a reality show recap podcast—rather than using generic messaging across all shows. Founders should equip hosts with clear proof points and stories, but allow enough flexibility for the host’s voice and humor to drive authenticity and trust.

Treat podcast measurement as a mix of direct and directional signals instead of expecting clean last-click attribution. Brands typically rely on unique promo codes, vanity URLs, and post-purchase surveys to capture self-reported influence from specific shows, then look for broader lift in branded search, direct traffic, and category demand during and after campaigns. Little Spoon, for example, treats podcasting as a channel that sits across the funnel and uses incremental learnings over years to inform how much budget to allocate rather than judging performance on a single, short campaign.

A few recurring mistakes include over-investing in one big show, underestimating the impact of placement, and ignoring creative context. Asset put the majority of its $60,000 budget into a single flagship show where its ad ran toward the end of the episode after multiple big-spending brands, and the lack of supporting visual branding on the show’s video channels hurt performance. Another mistake is assuming that a large listener base automatically means better conversions; in reality, Asset saw stronger results on smaller drag-oriented comedy podcasts that had less advertiser competition and tighter audience fit.

Networks like Acast are investing heavily in data and self-serve tools to make podcast buying more accessible to both big and small brands. Acast has built a database of roughly 1,800 creator profiles over three years and integrated Podchaser’s listenership data into its self-serve portal so advertisers can input business type and target zip codes to discover relevant shows. The company is also using AI and engineering resources to connect advertisers with cross-published content on YouTube and Instagram, and to enable dynamic ad insertion that can spread effective creative from live reads to other shows.

Podcast ads should complement, not replace, your core performance channels, especially if you’re still capital constrained. Asset turned to podcasts partly because of censorship on Instagram and TikTok, but ultimately concluded that, given limited capital, its budget was better spent on performance marketing that more reliably converted customers at that stage. For most startups, podcasts make the most sense as an additional trust and storytelling layer once you have a solid acquisition engine and can afford longer testing cycles.

Expect to test over multiple months and iterations before you can make a confident call. Brands like Little Spoon spent years experimenting with different shows, genres, and talking points before treating podcasts as a channel that sits across the entire funnel and planning to maintain or even increase podcast spend in its 2026 marketing mix. Early signals like traffic spikes and code usage by show are helpful, but the real value often appears as cumulative lift in brand awareness and trust that compounds over time.

AI and richer data are making podcast ad buying more targeted and scalable, which benefits founders who want to avoid guesswork. Acast’s use of AI and a dedicated engineering team enables features like smarter audience–show matching, self-serve discovery based on business type and geography, and dynamic insertion of winning creatives across a broader set of shows. Combined with research like Triton Digital’s Q3 2025 Podcast Ranker, which links listening patterns to retail behaviors, this shift should make it easier for startups to find pockets of high-intent listeners without matching the budgets of large advertisers.

It’s usually the wrong time if you’re pre–product–market fit, heavily cash constrained, or under pressure to show immediate payback on every dollar of ad spend. Even proponents like Acast’s CEO acknowledge that "everybody is interested in podcasting [ads], nobody has gone all the way in because it’s hard to buy and measure the ads," which makes the channel better suited to brands that can afford long-term testing. Asset’s founder, for instance, doesn’t plan to revisit podcast ads until at least mid‑2026 or after the next funding round, underscoring that timing and runway matter as much as channel fit.

Podcast advertising is a format where brands pay hosts or networks to promote products within episodes, typically via host-read or pre-produced ad spots. For DTC and startup brands, the appeal has historically been the authenticity of host endorsements plus trackable calls-to-action through unique promo codes and URLs that convert engaged listeners into customers.

Podcast advertising can still be effective for startups, but the bar is higher as major advertisers like Capital One and Coca-Cola increasingly treat podcasts as an awareness channel. The influx of big-brand budget has raised competition on popular shows, so smaller brands now need more disciplined testing, sharper audience fit, and better placements to stand out and drive measurable ROI.

Startups should treat podcast ads as a multi-show test rather than a one-off experiment, which often means committing a five-figure budget to get clear learnings. Asset, a butt-care startup, spent about $60,000 across several shows—with the majority going to one flagship podcast—before deciding that, for now, performance channels were a better use of limited capital.

Host-read ads are custom messages delivered by the podcast host in their own voice, often integrated into the show’s content and perceived as personal recommendations. Dynamically inserted ads are pre-recorded spots that ad-tech systems place into different episodes and shows based on targeting rules, enabling brands like Dunkin’ to turn live reads from shows such as “Giggly Squad” into reusable creative that can be passively served across other podcasts.

Smaller niche shows often outperform big celebrity podcasts for early-stage brands because there is less ad clutter and tighter audience alignment. Asset, for example, saw weaker performance on the large LGBTQ-focused show “The Bald and the Beautiful,” where its ad followed big spenders like Wayfair and BetterHelp, but achieved its highest traffic and conversion on smaller drag-oriented comedy shows like “Very Delta with Delta Work.”

Start with where your customers actually spend time, recognizing that audiences are multifaceted and listen beyond obvious category shows. Little Spoon, a kids’ food brand targeting millennial parents, discovered its customers listened not only to parenting content but also to lifestyle shows like “The Toast,” true crime series like “Morbid,” and news podcasts, and adjusted its partnerships to reflect that full spectrum.

Research from Triton Digital’s Q3 2025 U.S. Podcast Ranker shows that podcast listening patterns correlate with retail behavior at scale. For example, 87.6% of true crime listeners over-index as big-box retail shoppers, while 51% of tech content listeners over-index with department stores, meaning genre choice can influence the types of shoppers your ads reach.

High-converting podcast ads typically lean into specific customer pain points, clear benefits, and a simple, memorable offer, while still allowing the host to speak naturally. Little Spoon, for instance, increased emotional resonance by updating talking points on a reality TV recap podcast to emphasize how its products solve “mealtime drama” for parents, rather than using generic parenting language.

Placement within an episode matters: ads buried at the end of a show after multiple other sponsors can suffer from listener fatigue and lower recall. Asset’s underperforming ad on “The Bald and the Beautiful” ran toward the end of the episode after major advertisers, reinforcing the value of negotiating better positions and ensuring enough frequency across episodes to build recognition.

Visuals and cross-channel distribution can significantly enhance podcast ad performance by reinforcing brand recognition for listeners who also watch clips or follow hosts on social platforms. Asset’s campaign suffered from a lack of brand imagery on the show’s video channels, whereas networks like Acast actively help creators monetize cross-published content on YouTube and Instagram to give advertisers more touchpoints.

Most brands use a mix of unique promo codes, vanity URLs, and post-purchase surveys that ask how customers discovered the brand to attribute impact at the show level. In parallel, they monitor directional metrics like branded search, direct traffic, and overall sales lift during campaigns, treating podcast ads as a multi-touch channel rather than expecting precise last-click attribution.

Common mistakes include over-concentrating budget on a single big show, ignoring episode placement, and failing to align the show’s audience with the brand’s core customer. Asset’s experience—heavy investment in a flagship show with weak unit economics versus stronger performance from smaller, better-aligned podcasts—highlights why testing across multiple shows and genres is essential before scaling.

Acast supports advertisers by using a database of about 1,800 creator profiles and data from its Podchaser acquisition to match brands with shows based on business type and geographic focus. Through its self-serve marketplace, advertisers can input details like target zip codes and discover shows whose audiences align with their desired demographics, while AI and a team of 100 engineers optimize targeting and dynamic ad insertion.

Podcast ads can be a valuable alternative channel for brands that face content restrictions on platforms like Instagram and TikTok, especially for sensitive or niche product categories. Asset turned to podcast advertising after encountering censorship on paid social for its butt-care serum, using the host-read format to communicate efficacy in a more matter-of-fact, narrative-driven way than typical social ads allowed.

Founders should plan for a multi-month test phase with enough episodes and shows to gather reliable data, rather than judging the channel on a single short flight. Little Spoon spent years iterating across different podcasts and creative angles and now treats podcasting as a full-funnel channel, budgeting to maintain or increase its podcast spend in its 2026 media mix based on incremental learnings.

Podcast ads tend to work best when you have at least some product–market fit, a functioning acquisition engine, and enough capital to tolerate less precise attribution. Asset’s founder, for example, decided to pause further podcast testing until at least mid‑2026 or after the next funding round, recognizing that the channel’s learning curve and cost structure demand a longer runway.

Dynamic ad insertion is a technology that allows networks to automatically drop ads into podcast episodes based on targeting rules, enabling more flexible, scalable campaigns. Acast uses this to take live reads, like Dunkin’s sponsorships on “Giggly Squad” and other top shows, and turn them into clips that can be repurposed as passive ads across additional podcasts, increasing reach without re-recording from scratch.

AI and automation are making it easier to match brands with the right shows and to manage complex buys across a fragmented podcast ecosystem. Acast, for instance, relies on AI and a large engineering team to power its self-serve tools, ingest Podchaser listenership data, and help advertisers reach specific listener segments across podcasts, YouTube, and social channels more efficiently.

Yes, podcasts can serve both performance and brand objectives when approached strategically across the funnel. Little Spoon now positions the medium as touching every part of the funnel—from first-touch awareness on broad lifestyle or true crime podcasts to mid- and bottom-funnel reinforcement through repeated host reads and tailored messaging—which informs its decision to keep or grow podcast investment in future budgets.
