Executive Summary

Publishers, publicity firms, podcast networks and large retailers currently cannot scale discovery or measurement of book mentions across the rapidly growing podcast ecosystem, relying on manual transcript review that misses organic mentions and leaves earned media unquantified for roughly 100,000 institutional customers. This pain means PR teams lose attribution, retailers miss sales signals, and marketing ROI is opaque. You could build a SaaS pipeline that ingests audio/transcripts, applies tuned ASR and LLM models to extract and disambiguate book mentions, link each hit to metadata (title, author, ISBN), provide timestamps, confidence scores, and deliver dashboards, alerts and APIs for reporting and affiliate/retailer integration. Offer enterprise features—batch exports, SLAs, and publisher integrations—to make the product actionable in publicity and retail workflows. The timing is attractive: a $1.2B addressable market (100k buyers × $12k ACV), growing podcast listenership and ad spend, and improving transcription/LLM accuracy that lowers engineering costs; market score 86/100 and revenue potential 78/100 suggest a solid opportunity. Competition is medium, so the most practical path to win is focusing on high precision, ISBN reconciliation, and tight integration into publisher/retailer systems rather than a generic transcript search. You’ll need to be realistic about risks—noisy audio, casual or ambiguous mentions, false positives, and the enterprise sales motion—but with early pilots at a few publisher networks and a clear metrics-driven ROI (mentions → sales/coverage), this is a defensible product with a clear route to $12k+ ACV deals.

Market Opportunity

Index podcast transcripts to surface books mentioned across episodes targets a $1.2B = 100,000 potential institutional customers (publishers, publicity firms, podcast networks, retailers, large author teams) × $12,000 ACV total addressable market with medium saturation and a year-over-year growth rate of 20% YoY (based on IAB/PwC reported podcast ad & audience growth and rising spend on podcast discovery tools).

Key trends driving demand: Podcast listenership and ad spend are growing — more audio content increases demand for search, discovery, and measurement of earned mentions.; AI transcription and LLM extraction are reaching practical accuracy for noisy consumer audio — this lowers the engineering cost to build structured mention pipelines.; Publishers seek measurable earned media channels — podcasts are increasingly treated as measurable publicity, creating demand for mention-level analytics.; Shift to API-first tooling and integrations — publishers want analytics that plug into their existing CRM/BI systems to inform campaigns and attribution..

Key competitors include ListenNotes, Podchaser, Descript.
