Vendor lock-in tax — a SaaS data vault that makes your data portable

Large mid-market and enterprise firms are accumulating 20–50 point SaaS applications each, leaving customer and operational data fragmented and effectively taxed by vendor lock‑in when they try to migrate, consolidate, or comply with portability requests. This problem affects a global population of roughly 2,000,000 mid-market and enterprise firms and underpins an addressable need estimated at $48.0B (2,000,000 firms × $24K ACV) for vendor‑agnostic data management. The product would be a SaaS “data vault”: a canonical, vendor‑agnostic data layer with managed connectors, automated schema mapping powered by ML/LLMs, rights- and provenance-aware export formats, and both managed and self‑hosted deployment options to meet compliance requirements. The core deliverables are persistent, queryable canonical records, one‑click legal‑grade exports (GDPR Article 20 compliance), and a connector marketplace that reduces the ongoing “lock‑in tax” and lowers switching costs. This is attractive now because three forces converge: rapid SaaS proliferation driving fragmentation, expanding portability and privacy regulations (GDPR Article 20 and many national laws), and ML/LLM advances that meaningfully cut the cost of building and maintaining mapping/ETL pipelines. Market and revenue signals are compelling (Market Score 92/100, Revenue Potential 90/100) and the timing to productize automated, scalable portability is strong. To stand out you must combine rigorous end‑to‑end provenance, legally defensible export formats, strong security and enterprise SLAs, and ML automation that materially lowers TCO versus hand‑built integrations. Be honest that the challenges are significant: initial connector coverage and edge‑case mappings, customer inertia, and the engineering and trust investments required to win enterprise contracts; these are solvable but will require capital, partnerships, and a patient sales cycle.
