Executive Summary

Marketers, publishers and direct-to-consumer brands—particularly the roughly 2 million businesses that could each spend about $3,000 a year—are losing deterministic ways to identify visitors because of third‑party cookie deprecation and tightening privacy laws, which creates gaps in personalization, attribution and revenue optimization. Companies are left choosing between invasive tracking that increases legal risk or noisy probabilistic approaches that raise customer acquisition costs and reduce conversion efficiency. You could build a consent‑first visitor identification platform that captures and cryptographically verifies consent at the point of engagement, issues verifiable consent receipts, and exposes persistent first‑party identifiers via lightweight SDKs and server‑side APIs for CDPs, analytics and ad platforms. Core capabilities would include front‑end consent capture, server‑side tokenization and matching, real‑time segmentation, and prebuilt integrations with the top 10 CDPs/ad platforms to deliver measurable lift without third‑party cookies. Delivering 5–15% conversion uplifts is realistic based on similar first‑party identity deployments, but the product will require rigorous security, legal validation and substantial integration work. The market is timely: cookieless browsers, GDPR/CPRA momentum and brands’ investments in server‑side first‑party data pipelines create demand, reflected in a market score of 88/100 and revenue potential at 86/100, though competition is high. To stand out you must make consent verification a core differentiator, target the underserved mid‑market with a simple UX and turnkey integrations, and secure distribution partnerships; otherwise incumbent vendors and large CDPs could outcompete you on reach. If you can commit 12–24 months to build robust integrations, invest in privacy/legal expertise, and execute a clear channel strategy, this idea is worth pursuing; without that focus, the competitive and integration barriers make it risky.
