Executive Summary

Creators and small marketing teams—about 15 million worldwide—spend disproportionate time turning long-form YouTube video into platform-ready posts for X, Instagram, LinkedIn and emerging channels; that work is repetitive, inconsistent in voice, and expensive for teams without dedicated editorial resources. The result is missed posting cadence, variable audience engagement and high per-post labor costs that limit scaling for independent creators and boutique agencies alike. You could build a product that ingests YouTube transcripts, detects speaker characteristics, and outputs platform-specific drafts (tweets, Instagram captions, LinkedIn posts, short hooks and headlines) along with optional scheduling and analytics. Priced around $300 ACV to a 15M addressable base, the arithmetic points to a $4.5B market; market attractiveness is high (market score 90/100, revenue potential 80/100) because LLMs and speaker-conditioned models now materially reduce manual editing, and platform fragmentation makes format-aware automation increasingly valuable. To stand out in a medium-competition field you’ll need rigor: high-fidelity, controllable voice conditioning; platform-aware templates and direct publishing integrations; and a human-in-the-loop editor to preserve brand safety and prevent hallucination. Be honest about challenges—trust around voice authenticity, copyright and moderation, and the operational burden of evolving platform APIs—and consider starting with agency pilots or vertical niches to validate ROI before scaling to the full 15M addressable market.
