Single Grain (Paid Ads) review
Founder-led (Eric Siu) revenue-marketing agency with sophisticated Mixed Media Modeling attribution and a strong content platform, but very broad (SEO+paid+content+creative+CRO across 5 ad channels), a small team for that breadth, and thin Clutch reviews (12).
Pricing: $10,000 Reported — not published by the agency

Verdict
Single Grain (founded 2009, led by Eric Siu) is a well-known revenue-marketing agency running paid across Google, Microsoft, Meta, LinkedIn, and TikTok with Mixed Media Modeling to balance spend, genuinely more sophisticated attribution than in-platform ROAS, plus 500+ companies served and a 3.2x average ROI claim. The concern the rubric surfaces is breadth over depth: it does SEO, paid, content, performance creative, CRO, and analytics with a relatively small team (10-49) for that range and enterprise-level clients, its public Clutch base is thin (12 reviews), and the brand is heavily tied to Eric Siu's personal platform. Strong on measurement and content credibility; validate that your specific paid channels get deep, senior attention.
