Single Grain started in 2009 as an SEO agency and was later acquired by Eric Siu in 2014 when the company was struggling. Siu turned it around and rebuilt Single Grain into a growth-focused digital marketing agency based in Los Angeles.
The agency specializes in working with SaaS companies, tech startups, and digital-first businesses. Their services cover SEO, paid media (Google Ads, Facebook Ads), content marketing, and conversion rate optimization. Clients have included Amazon, Uber, Salesforce, and Airbnb.
Single Grain’s team is lean and senior-heavy. They don’t sell cookie-cutter packages — each engagement is custom-built around the client’s growth goals, unit economics, and competitive landscape. This consultative approach attracts companies that have already tried basic marketing tactics and need a more sophisticated strategy.
Siu co-hosts the Marketing School podcast with Neil Patel, which publishes daily episodes and has accumulated millions of downloads. This content platform, along with Siu’s Leveling Up podcast on entrepreneurship, generates significant awareness for the agency.
The agency has earned recognition from Clutch, G2, and various digital marketing publications. Their blog and YouTube content on marketing strategy draw substantial organic traffic, and their case studies show impressive ROI numbers — they’ve documented instances of doubling and tripling client revenue through integrated campaigns.
