About MADX Digital

MADX Digital is a London agency founded in 2020 that works with B2B SaaS on SEO, content, digital PR and, more recently, AI search. It publishes SEO packages from $2,500 per month on its own site, the lowest entry rate any agency in this ranking states directly rather than through a directory listing.

Clutch records 4.9 from 13 reviews, a $5,000 minimum and most projects between $10,000 and $49,999, and names MoonPay, Postalytics and Thunes as clients. The agency states 50+ SaaS clients and 12.2M AI search impressions; the impressions figure is self-reported and the definition behind it is not published.

Ratings elsewhere

Ratings published by third parties, recorded August 2026. AI Agency Radar does not collect reviews and does not combine these into a score of its own.

Our verdict

MADX is the most accessible entry point in this ranking for a SaaS company that wants to start on AI search without committing five figures a month. It publishes its own rate, holds a strong score across 13 Clutch reviews and has kept a narrow vertical focus since 2020. Two limits matter. Clutch records 70% of its clients as small businesses under $10M in revenue, so there is no public evidence of enterprise scale delivery, and the 12.2M AI search impressions headline is an unexplained metric rather than a methodology. It ranks fifth because price transparency and fit are real while the technical case is thinner than the four agencies above it.

Pros

  • Publishes a $2,500 per month starting rate on its own site, not only a directory minimum
  • 4.9 from 13 Clutch reviews across a single vertical held since 2020
  • Named fintech and B2B SaaS clients including MoonPay and Thunes

Cons

  • Clutch records 70% of clients as small businesses under $10M revenue, so enterprise delivery is unproven
  • The 12.2M AI search impressions figure is self-reported with no published definition or method behind it
