Castos review for private company podcasts: what its pages show

Castos review: the verdict for a private company podcast

Castos is a podcast hosting service that also runs private shows. For an HR, internal-communications or training lead, three questions matter: who can hear the show, how access ends when someone leaves, and what each plan allows. Castos answers the first two on its own pages. Each private listener gets a personal feed, and removing the person revokes that feed.

The plan details are where a company has to read closely. The free listener app starts on Growth, the private list is capped by plan, and single sign-on appears only on the contact-us Castos Premium plan. This site has not used Castos. Everything below comes from Castos pages and a few outside pages, read on October 18, 2026.

Strengths the vendor's pages support

These points are claims on Castos pages, not results we measured.

• Personal feeds: each private subscriber gets their own feed, which Castos says works in Apple Podcasts, Overcast, Pocket Casts, Castro and most apps that add a show by feed address.
• Ending access: Castos says a canceled subscriber's feed is revoked, and nobody else needs a new link.
• A listener app from Growth: people sign in with their email and a one-time code, with no feed address to copy. Offline downloads are off by default and can be switched on.
• Standalone use: the internal podcast page says Castos works on its own, with no WordPress site needed, and that public and private shows can sit in one account.
• A 14-day free trial, with a cancel-anytime promise.

Limits and poor fit for company listening

• The entry plan has no listener app. On Essentials, staff listen through the podcast app they already use, with a personal feed.
• Private lists are capped: up to 100 on Essentials, 250 on Growth and 500 on Pro. Past 500, Castos describes an add-on sold in blocks of 500, arranged after you start a trial, or the custom Premium plan.
• Single sign-on is listed only on Castos Premium. The enterprise page also speaks of Castos Enterprise, and the pages we read do not say whether that is the same offer.
• A shared group link cannot be revoked person by person, Castos says, and it advises individual feeds for anything paid.
• Castos's own guide warns that once an episode is downloaded to a phone, there is no way to retrieve or delete it.
• Its pages differ in small ways. Private podcasting is described as included on every plan, yet the app needs Growth. A guide says every user can create as many private podcasts as they like, yet each plan caps private subscribers.

Plans and cost: what to check before you pay

Castos lists Essentials, Growth, Pro and a contact-us plan called Castos Premium, with a monthly or annual billing choice. This page lists no prices, because they depend on the billing toggle and can change. Read them on the live page. The Castos pricing guide sets out what each plan adds.

The trial asks for a card, according to Castos's own comparison page, and the card is not charged until the trial ends. Then run one cost check with your own headcount. Divide the plan's monthly fee by the number of people you will actually invite, not by the cap. A company of 120 does not fit the 100 on Essentials, so Growth is the first plan with room, and it is also the first with the app. A company of 600 is past the 500 on Pro.

What this review is built from, and what it cannot tell you

The sources are the Castos pricing, private podcasting, internal podcast, mobile app, enterprise and guide pages, plus its own comparison page, all listed at the bottom. This site ran no test. We cannot say how the dashboard feels, how reliably invitations arrive, or how fast support answers. Castos pages show a review-site score. We do not repeat it, because this site publishes no ratings.

Software reviews often carry links that pay the publisher. The FTC's endorsement guides, published as 16 CFR Part 255, treat a review site that earns money from link referrals as a case that should disclose it clearly and conspicuously. This site's disclosure is linked in the footer of every page.

Who should choose Castos and who should look elsewhere

Castos fits a company of up to about 500 people that wants staff to listen in ordinary podcast apps or a free app, and wants to remove people one at a time. It also suits coaches who sell a client-only feed.

Look elsewhere if staff must sign in through your own identity system on a plan you can start online: Castos vs Podbean shows who lists that. Look elsewhere if you have thousands of listeners or want a branded app without a custom contract. The host shortlist names the options.
