Single Grain

Single Grain is a Los Angeles-based, remote-first digital marketing agency serving both Fortune 500 companies and startups across SEO, paid media, and content marketing. It offers genuinely proprietary tools — ClickFlow (SEO content optimization) and Karrot.ai — alongside a distinctive "Search Everywhere Optimization" point of view, and holds a real minimum project size of $10,000+ per its Clutch profile. Clutch reviewers specifically praise the agency's specialty knowledge, with one CMO client noting Single Grain avoided the "jack of all trades, masters of none" feel common among broader agencies.

Two specific, independently-sourced inconsistencies are worth flagging directly for this review. First, reported company size varies dramatically across directories: LinkedIn lists 51-200 employees, while Clutch lists 10-49 — a real, unresolved discrepancy about actual current team scale, not a rounding difference. Second, Single Grain's G2 profile has not been actively managed in over a year as of this research — a real signal about current engagement with that particular review platform, worth noting alongside its more active Clutch presence.

It's built for companies with product-market fit ready to invest at least five-figure budgets into a strategic, high-touch agency relationship. It's explicitly a poor fit for very early-stage startups, local-only businesses, or anyone seeking low-cost, short-term campaigns.

The agency's differentiation, per independent comparison against peers like NP Digital and Directive, comes from its combination of media, content, and CRO work alongside its proprietary tools and Search Everywhere Optimization framework — a genuinely distinctive positioning versus agencies offering standardized, packaged deliverables. Reviewers specifically praise direct access to the specialists actually running campaigns rather than being routed exclusively through an account manager layer.

A specific, sourced gap worth taking seriously: one independent SEO-focused publication (Onely) explicitly states Single Grain "lacks the AI search optimization layer enterprise brands need for 2026 visibility" — a direct, specific criticism from a source specializing in exactly that evaluation criterion, worth confirming directly if GEO/AEO capability is a priority for your engagement.

• No published rate card. Third-party directories consistently cite a $10,000+ minimum project size, with engagements structured as monthly retainers or project-based work.
• Reported retainer ranges vary enormously across sources: industry reports cite $10,000-30,000+/month for multi-channel engagements, while Single Grain's own budget intake form reportedly references a $3,000-100,000+ range — one of the widest self-disclosed ranges found anywhere in this research.
