Ploy is an AI growth platform that builds, optimizes, and operates websites and marketing channels autonomously. Its AI agents handle design, copywriting, campaign execution, A/B testing, visitor identification, lead scoring, and CRM data syncing — running continuously in the background so marketing teams can execute at speed without growing headcount. Founded in 2025 by Bryant Chou — co-founder and CTO of Webflow from 2013 to 2025, where he built the core product, CMS, and hosting powering approximately 1.5% of the internet — Ploy packages full-funnel marketing workflows as pre-built automation strategies called PloyBooks. The platform serves three core pillars: Web (AI website builder with SEO and conversion optimization), Grow (visitor identification, personalized outreach, and lead scoring), and Ads (creative generation and full-funnel attribution). Over 13% of Y Combinator's P26 batch companies use Ploy, including Hex and Clay. In June 2026, Ploy raised a $27 million Seed round co-led by First Round Capital and Y Combinator, with notable angels including Lenny Rachitsky, Eoghan McCabe, Josh Kim (Cursor), and Sherwin Wu (OpenAI).
