Single Grain

Single Grain is a remote-first, AI-native revenue marketing company founded in 2009. It builds pipeline-focused marketing programmes for venture-backed startups and Fortune 500 organisations, with the stated aim of compounding into durable revenue systems rather than short-lived campaigns. Its technical work spans search engine optimization, paid advertising, content marketing, conversion rate optimization, creative strategy and AI implementation - an overlapping set of disciplines relevant to answer engine optimization and the visibility of brands in AI-mediated search.

The firm operates two products of its own. ClickFlow is an AI-assisted SEO product; Karrot provides personalized LinkedIn advertising. Single Grain reports having helped more than 500 clients achieve measurable growth, working across verticals including SaaS, ecommerce, education and blockchain.

Single Grain evolved from a struggling SEO agency after it was acquired by Eric Siu in 2014. Its stated culture emphasizes continuous learning, rapid experimentation, collaboration and resilience, alongside a focus on improving both client outcomes and the internal systems that support delivery.
