Single Grain

Single Grain positions itself as an AI-native marketing company that goes beyond traditional agency models. Founded in 2009 and led by CEO Eric Siu, the firm has built a reputation for tying every marketing dollar to measurable revenue outcomes. With a client roster that includes Amazon, Uber, and Salesforce, Single Grain has proven it can deliver at scale. The agency's recent pivot to "AI-native execution" reflects a broader industry shift, but what sets them apart is their willingness to deploy AI systems directly into client operations rather than just advising on them.

The agency's core capabilities span the full digital marketing spectrum: SEO, paid media, content marketing, conversion rate optimization, and analytics. What makes Single Grain unique is their early adoption of Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO) -- ensuring clients appear in AI-powered search results from ChatGPT, Perplexity, and other LLM-based tools. They also offer hands-on AI implementation, installing agents and automated workflows inside a client's martech stack. This operational focus means results start in month one, not after a lengthy strategy deck.

Pricing is custom and starts at a minimum of $10,000 per project, with most engagements structured as monthly retainers. There is no free plan or trial. While this puts Single Grain out of reach for bootstrapped startups, the investment makes sense for growth-stage companies that need a strategic, high-touch partner. The agency's ROI-focused approach means every channel is optimized for pipeline and revenue, not vanity metrics. Clients can expect regular reporting, strategy discussions, and a team that feels like an extension of their own marketing department.

Single Grain is best suited for SaaS, technology, and ecommerce companies that have achieved product-market fit and are ready to invest five-figure budgets into digital acquisition. The agency excels in complex buying cycles where attribution and revenue alignment matter most. Early-stage startups or local businesses with limited budgets will likely find the minimum spend prohibitive and may be better served by freelancers or smaller agencies until they reach a stage where Single Grain's approach makes financial sense.

In a crowded agency landscape, Single Grain stands out for its AI-first execution, proven track record with enterprise clients, and relentless focus on ROI. The agency's thought leadership -- through its blog, podcasts, and educational content -- further reinforces its authority. While the high minimum spend and occasional communication strain during rapid scaling are valid concerns, the overall value proposition is strong for companies that need a growth partner capable of delivering measurable, revenue-linked results from day one.
