Executive Summary

About 70% of online shopping carts are abandoned, a problem that directly hits revenue for a wide range of merchants—from high-growth DTC brands to mid-market retailers—who are simultaneously facing rising customer acquisition costs and thinning margins. Merchants lack a privacy-compliant, reliable way to identify visitors, capture consented contact channels, and trigger automated rescue flows that actually convert before the customer leaves the session or the site loses the signal. You could build a consent-first visitor identification platform that operates server-side, creates pseudonymous but persistent IDs tied to verified, opt-in channels (email, SMS, push), and enables automated cart-rescue journeys with real-time intent signals, progressive profiling, and clear consent records. The product would include lightweight SDKs and server APIs for integration, deliverability tooling and SMS verification, built-in A/B testing and ROI measurement, and turnkey workflows that recover revenue without relying on third-party cookies. This is an attractive moment: cookie deprecation and stronger privacy regulation are forcing merchants to adopt server-side, consent-first identity solutions, and a global addressable market of roughly 10 million merchants at an average $1,500 ACV implies a $15.0B opportunity (market score 95/100; revenue potential 94/100). Behavioral benchmarks show email-only recovery often yields single-digit percentage improvements while consented omnichannel approaches (with SMS and push) can produce materially higher lift, which justifies dedicated tooling as CAC increases. To stand out you must be explicit about privacy and consent, instrument server-side identity with auditable consent records, and tightly integrate deliverability and verification so merchants see measurable ROI quickly; consider commercial models like low-friction trials or pay-for-performance to reduce adoption risk. Be honest about the hard parts: compliance across jurisdictions, SMS costs and carrier relationships, and integration friction—all of which require upfront investment and clear value propositions to win a medium-competitive category.
