Single Grain is a Los Angeles–headquartered digital marketing agency focused on driving persistent, measurable growth for “remarkable companies.” Founded in 2009 and rebuilt under CEO Eric Siu after a turnaround acquisition in 2014, the agency has evolved from a traditional SEO shop into a full-funnel growth partner for B2B and B2C brands. They emphasize revenue over vanity metrics, tying strategy and execution to KPIs like CAC, LTV, pipeline, and attributable revenue.
The firm specializes in paid media, SEO, content marketing, performance creative, conversion rate optimization (CRO), and data & analytics, with particular depth in SaaS and technology, ecommerce, education, and Web3/crypto. Single Grain positions itself as AI-forward, using programmatic SEO, AI-powered CRO, and “Search Everywhere Optimization” (AEO/GEO/LLMO) to capture visibility across search engines, social platforms, and AI assistants. They operate as a remote-first, elite team that integrates strategy, creative, and execution across channels.
Single Grain’s client portfolio spans Series A startups to global enterprises such as Amazon, Uber, Salesforce, Nextiva, and Lever. Case studies highlight substantial lifts in traffic, signups, conversions, and ROAS, including multi-hundred-percent increases in organic traffic, significant CPL reductions, and double- or triple-digit revenue growth for long-term clients. Their minimum project sizes generally start at $10,000+, reflecting a focus on high-impact, custom engagements rather than commoditized services.
Beyond client services, Single Grain invests heavily in thought leadership and its own product ecosystem. The company runs a high-traffic blog, the Leveling Up and Marketing School podcasts (with 100M+ combined downloads), and an active YouTube channel for marketers. They have also incubated products like ClickFlow (SEO experimentation platform) and Karrot.ai (LinkedIn ABM automation). Single Grain maintains a strong brand around leveling up marketers and founders, while publicly warning against scam sites and clones, affirming https://www.singlegrain.com/ as its only official domain.
