About Single Grain

Single Grain is a digital marketing agency focused on paid advertising, SEO, and content marketing, led by Eric Siu — helping SaaS, crypto, and e-commerce companies grow revenue efficiently.

Editorial Assessment

Single Grain is a full-service digital marketing agency headquartered in Los Angeles, California, best known for its growth-focused approach across paid media, SEO, and content marketing. The agency was originally founded in 2009 and later acquired by Eric Siu, who has since built it into a well-recognized brand in the performance marketing space. Eric Siu is also the co-host of the popular Marketing School podcast alongside Neil Patel, giving Single Grain significant content authority and a built-in audience of marketing professionals. The agency serves a broad range of clients, with particular strength in SaaS companies, e-commerce brands, and venture-backed startups looking to scale quickly. Single Grain specializes in paid advertising across Google Ads, Meta, LinkedIn, and YouTube, with complementary services in technical SEO, conversion rate optimization, and video marketing. Their content marketing practice is especially notable: the team produces detailed, long-form guides and thought leadership content designed to rank for competitive keywords while generating organic lead flow. Single Grain positions itself as a lean, agile alternative to large holding-company agencies, with senior-level involvement on accounts rather than delegating to junior account managers. The agency has published extensively about its own growth strategies, offering clients transparency into the tactics they employ. Their case studies span industries including fintech, health tech, B2B software, and direct-to-consumer e-commerce. Retainers are custom-quoted based on scope and channel mix, and they do not publish standard pricing.
