What is Single Grain?
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.

Who Single Grain is for
A strong fit for
Single Grain is best suited for growth-focused SaaS, technology, ecommerce, and other B2B or B2C companies that already have product, market fit and are ready to invest at least five-figure budgets into performance marketing. Ideal clients want a strategic partner to own and optimize multi-channel acquisition, not just a tactical vendor for one-off campaigns.
Probably not for
Single Grain is typically not a fit for very early-stage startups with minimal budget, local-only microbusinesses seeking low-cost, short-term campaigns, or teams looking for a self-serve software tool instead of a hands-on strategic agency relationship.
How Single Grain compares
Compared with other growth and performance agencies, Single Grain positions itself squarely at the intersection of AI-driven innovation and revenue accountability. While many competitors offer SEO or paid media in isolation, Single Grain leans into full-funnel strategy, combining AI-first SEO, multi-channel paid acquisition, content, CRO and analytics into integrated programs built around business KPIs. This makes them particularly attractive to SaaS and technology companies that need a partner capable of owning and optimizing the entire acquisition engine.
Against peers like NP Digital, WebFX, KlientBoost, Directive and Siege Media, Single Grain’s differentiation comes from its strong media plus content plus CRO mix, its Search Everywhere Optimization point of view, and the presence of proprietary tools like ClickFlow and Karrot.ai. On the flip side, its bespoke, higher-ticket engagements and lack of standardized pricing can feel less accessible or predictable for smaller organizations or buyers who prefer packaged offerings. Overall, Single Grain is a strong fit for brands seeking aggressive, experiment-driven growth and willing to invest in a close, strategic agency relationship.
