Executive Summary

Many marketers and engineering teams are losing reliable, consented visitor identity as GDPR/CPRA enforcement and third‑party cookie deprecation break traditional tracking; mid‑market and SMBs in particular struggle to personalize, attribute and grow revenue without risking compliance. This results in wasted ad spend and weaker conversion funnels for an addressable set of roughly 2,000,000 businesses that currently spend on martech. You could build an API‑first, server‑side identity platform that captures verifiable consent, resolves consented identifiers into privacy‑preserving profiles, and pipes hashed signals to analytics, CRM and ad endpoints via developer SDKs and prebuilt integrations. The product would prioritize consent receipts, audit logs, and real‑time consent checks so teams can safely do personalization and attribution without third‑party cookies. The market is ripe: estimated $6.0B TAM (2,000,000 businesses × $3,000 ACV), a market score of 88/100 and a revenue potential of 86/100, driven by accelerating regulatory pressure and the industry shift toward first‑party identity. Developer‑friendly, server‑side solutions also match current engineering preferences, lowering adoption friction. You can differentiate by marrying strong privacy controls (consent verification, immutability, audit trails) with a developer experience (lightweight APIs, server SDKs, turnkey integrations) that incumbents often lack, but be honest that competition is medium and the hard parts are building trust, broad integrations and scale. If you can execute on reliability, compliance proofs and a clear ROI model at ~ $3k ACV, this idea has practical legs.
