About Zaymo

Zaymo builds the tools AI agents use to do marketing, for the largest ecommerce brands in the world. ~500 brands, including Grüns, Harry's, AG1 and Liquid I.V. (Unilever), run on Zaymo. Our wedge is interactive email. We made emails work like websites: shoppers buy, swap or skip a subscription without leaving the inbox. It closes 75%+ of the brands we pitch and put us inside the email programs of hundreds of the best brands in ecommerce. Now we're building the agents that run those programs. Brands pay agencies ~$70k a year to run email, and the good ones run one or two tests a month. Our agents audit the program, write and design on-brand campaigns, QA them, and run hundreds of experiments optimized for profit, not just revenue, with an expert human owning the outcome. We build for the agent a marketer already uses (Claude, via MCP), not yet another chatbot. $5M ARR, 5x'ing this year, consistently cash-flow positive.
