About
MADX Digital is a London agency that limits itself to SaaS businesses, with a visible tilt toward fintech and crypto clients. It sells generative engine optimization alongside traditional SEO, content, digital PR and link building, and its packages bundle prompt tracking across ChatGPT, Google AI Overviews and Claude. Clutch lists it as founded in 2020 with 10 to 49 employees, and the founders, Perry Steward (Head of SEO) and Toni Koraza (Head of Ops), are named on the about page.
Pricing is published in US dollars. Twelve-month retainers start at $3,500 a month and rise to $9,500, a one-off growth plan costs $4,500, and a per-placement link price list is public too. The case study library is large and specific: Postalytics, Nosto, MoonPay, Hola Prime and Orderful pages all name the client and give dated figures, mostly drawn from Ahrefs estimates with some GA4 and Search Console numbers. Some pages are candid about setbacks, such as a decline in Hola Prime leads after June 2026, and one page shows a headline figure that does not match its body text. Clutch shows 4.9 from 14 reviews, several from the same named clients.
What the record lacks: no G2 or Google review profile was found, no awards or partner certifications are documented, and the founders' backgrounds before MADX are not published, so their years in search are counted from the agency's founding. The SaaS-only focus means non-software buyers should look elsewhere.
