I learned about Helena, the world’s first self‑improving AI marketer, which has already generated $10M in sales for 20,000 businesses. It distinguishes itself by grading its own outputs and rebuilding any that miss quality criteria, covering ad optimization on Meta and Google, SEO content publishing to WordPress, Webflow, and Framer, and email optimization across Klaviyo, Mailchimp, and Brevo. It also sends a daily brief summarizing performance and recommendations. This initiative ties into my broader interest in AI agents automating workflows, see ai agents and product quality for related insights.
