Recover hidden/deleted social posts using archived/indexed caches

Many creators, roughly 20 million small creators and SMBs globally, plus researchers, legal teams and journalists, routinely lose access to deleted or hidden social posts and have no reliable way to recover or prove what was once public. The consequences are concrete: lost evidence for audits and litigation, gaps in brand reputation management, and incomplete analytics for businesses that rely on historical social signals. You could build a continuous archival platform that performs real-time snapshots across centralized and federated networks, stores content-addressable immutable archives with signed manifests and chain-of-custody, and exposes search, alerting and an API for retrieval and legal export. Monetization is straightforward: a baseline archival/analytics subscription around $300 ARR per account (the basis for a $6.0B TAM from 20M potential customers) with enterprise add-ons for eDiscovery, long-term retention and regulatory reporting. This market is attractive now because three forces converge: platform decentralization increases fragmentation and the likelihood content will be missed, regulatory scrutiny raises demand for immutable records, and declines in storage and edge compute costs make continuous capture economically feasible—hence the market score 90/100 and revenue potential 80/100 are credible. To stand out in a medium-competition landscape, prioritize verified chain-of-custody and low-latency capture for federated sources, best-in-class deduplication and metadata enrichment, and legal/partner integrations, while being candid about hard challenges such as platform TOS, privacy compliance, ingesting ephemeral/private content, and the operational cost of continuous global crawling.
