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.

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
