Real-revenue cases

It replaces marketers hand-coding personalization or hiring someone to do it; the founder says nearly 100% of customers aren't switching from a competitor, meaning the need was largely unserved by tools. People pay monthly, and $10K in preorders came in within days.
Marketers at online businesses pay a monthly SaaS subscription, billed through Stripe; demand was validated first through preorders before launch.
Marketers hand-coding or outsourcing site and email personalization

The audience co-founder Brennan had built through his marketing course, plus marketers drawn in by the founders tweeting about their experiments; preorder customers became the first users.
03
