How the agent runs it

Podcast hosts submit a raw episode file via a simple intake form; the agent team autonomously transcribes, identifies the three highest-tension 60-second moments, scripts a narrator hook, generates a voiceover overlay, assembles audiogram assets with branded waveform visuals, writes platform-specific copy for Apple, Spotify, and YouTube, and delivers a zipped production package — all within 90 minutes. The CEO agent queues, routes, and quality-scores every deliverable before it reaches the client's inbox. Stripe handles subscriptions and invoices without human involvement.

Who this is for

Ideal for a solo operator with a background in audio production, content marketing, or SaaS tooling who understands podcast workflows but wants to own a productized service instead of freelancing. They do not need to edit audio themselves — they just need to configure the pipeline, sign the contracts, and handle the rare escalation. This suits someone who wants a capital-light business with recurring revenue and zero employee overhead.

Market opportunity

There are over 4 million active podcasts globally as of 2024, yet fewer than 15% of independent shows produce consistent trailer or promotional clip content due to production cost and time. Trailer clips are now the primary discovery mechanism on Spotify and YouTube Shorts, creating urgent demand. The rise of accessible audio APIs (Descript, ElevenLabs) in 2023–2024 has made automated clip assembly technically feasible for the first time at sub-$1 marginal cost per package.

Boss agent: HELM (High-priority Episode Lifecycle Manager)

HELM receives every inbound job, assigns it to the correct specialist agent in sequence, monitors completion timestamps against a 90-minute SLA, scores output quality against a rubric, and either approves delivery or routes back for revision before the client package is sent.

  • No deliverable leaves the system without a quality score above 82/100 on the internal rubric covering clip relevance, copy accuracy, and file integrity
  • All client audio files are deleted from Cloudflare R2 within 48 hours of package delivery to enforce data minimization compliance
  • Stripe payment confirmation must be verified before any job is enqueued — no credit or deferred billing exceptions

The agent team

🤖
SCALPEL (Transcript & Clip Selection Agent)
Receives raw audio, calls the Descript API for full transcription, scores every 60-second segment for tension, narrative hook density, and emotional contrast, then selects and exports the top three candidate clips as timestamped audio segments passed downstream.
🤖
HOOK (Trailer Script & Narrator Copy Agent)
Takes the winning clip transcript and episode metadata, writes a 15-second narrator intro hook in the client's brand voice, drafts three platform-specific description variants (Apple Podcasts, Spotify, YouTube), and passes all copy to the voice synthesis agent.
🤖
VOICE (ElevenLabs Synthesis & Audio Assembly Agent)
Sends the narrator script to ElevenLabs using the client's selected voice preset, receives the synthesized audio, and assembles the final trailer by prepending the hook narration to the selected clip, normalizing levels, and exporting a broadcast-ready MP3.
🤖
FRAME (Audiogram & Visual Asset Agent)
Generates a branded waveform audiogram image and a static thumbnail using the episode title and show art, packages them with the MP3 and platform copy into a structured ZIP archive, and uploads the complete deliverable to a time-limited client download link on Cloudflare R2.
🤖
LEDGER (Billing, Client Comms & Retention Agent)
Monitors Stripe for new subscriptions, failed payments, and upcoming renewals; sends automated delivery confirmation emails with download links; dispatches retry sequences for failed charges; and flags accounts with two consecutive unused monthly credits for a cancellation-risk alert to HELM.

Human touchpoints

// the only things that still need you

  • 👤 Signing the master service agreement and any custom enterprise contracts that require a legal entity signatory
  • 👤 Authorizing Stripe payouts above $5,000 to the business bank account when the payment processor flags them for manual review
  • 👤 Responding to brand crisis escalations — specifically, any client complaint alleging that a generated trailer clip misrepresented a guest's statements in a defamatory way

Monetization

Clients pay $299/mo for up to 4 trailer packages per month (one per weekly episode) or $89 per one-off trailer, billed via Stripe subscriptions and pay-per-use links. Upsell tier at $599/mo adds audiogram video rendering and LinkedIn/Instagram caption sets, increasing ARPU without additional human labor.

Key risks

  • Audio quality variance — heavily distorted or low-bitrate episode files can cause transcription failures that cascade into poor clip selection, requiring a fallback re-upload workflow.
  • ElevenLabs voice cloning consent liability — if clients submit audio containing guest voices and request cloned narration, the bureau must enforce strict consent gating or face DMCA and likeness claims.

Getting started

  1. 1
    Configure Descript and ElevenLabs API credentials
    Sign up for Descript's developer API and ElevenLabs' standard tier, store credentials in a secure environment vault (e.g., Doppler or AWS Secrets Manager), and verify transcription accuracy on three sample episodes before building any agent logic.
  2. 2
    Build the intake form and file intake pipeline
    Use Typeform or Tally to create a client submission form that accepts MP3/WAV uploads to Cloudflare R2, captures episode metadata (title, show name, brand voice notes), and fires a webhook to trigger the CEO agent on submission.
  3. 3
    Assemble and test the full agent team in Claude Managed Agents
    Deploy all five specialist agents with defined tool permissions and handoff schemas, then run 10 end-to-end test episodes covering edge cases — crosstalk, long silences, non-English segments — before accepting paying clients.
  4. 4
    Launch a Stripe billing page with two tiers
    Set up a $89 one-off SKU and a $299/mo subscription product in Stripe, embed payment links on a single-page Carrd or Framer site, and connect Stripe webhooks to the CEO agent so new payments automatically enqueue a job.
  5. 5
    Acquire first five clients via podcast Facebook groups
    Post in three to five active podcaster communities (Podcast Movement community, Facebook Podcast groups, Reddit r/podcasting) offering a free trial trailer for one episode in exchange for a testimonial, converting trial users to paid subscriptions within 7 days.
