SEO and AI search agency working only with B2B SaaS companies

MADX Digital is a London-founded search agency that works exclusively with B2B SaaS businesses. Its focus is helping software companies earn visibility both in Google and in the answers produced by AI assistants such as ChatGPT, Perplexity and Gemini.

The agency treats traditional SEO and generative engine optimisation as a single discipline. Technical work makes sure sites can be crawled and understood, while content strategy targets the questions and follow-up queries buyers actually ask. Digital PR and link building aim to secure mentions and links in third-party publications, and the team pays attention to keeping brand messaging consistent across the web.

Engagements follow a structured path: a discovery audit, a growth strategy, ongoing optimisation and reviews every 90 days. MADX works with SaaS companies at different stages, from early startups to established brands, with additional experience in fintech, AI technology and enterprise software. Prospective clients can start with an AI visibility audit or a short introductory call.
