About

Breaking B2B is a London search agency run by its founder, Sam Dunning, who is also known for the Breaking B2B podcast and a large LinkedIn following. Its LinkedIn company page dates it to 2020. It works only with B2B and SaaS companies and sells technical SEO, SEO content, link building, conversion and site structure work, plus a set of AI search services it names as answer engine optimization, generative engine optimization and LLM SEO. It also offers Reddit and YouTube marketing, and lists healthtech, martech, fintech, financial services, logistics and construction as focus industries.

The agency publishes its prices, which is uncommon. Tiered growth programs run from $5,500 to $20,000 or more a month, enterprise programs from $8,500 to $40,000 or more, and narrower plans start at $4,000 a month, on six or twelve month terms. The case study record is strong for an agency of this size. Named write-ups for RB2B, Proposify, Chattermill, VerifyTreatment and Prosperity Behavioral Health give concrete figures, such as a 77% rise in RB2B non-branded traffic over six months and a move from 5 to 32 monthly demos for VerifyTreatment. Several of these results are about AI search, including a rise in Chattermill's AI mention rate from about 20% to 80%.

What is missing: no Clutch, G2 or Google review profile was found, so there is no third-party rating to check, and no awards or partner certifications were found. The site has no about page or street address. LinkedIn lists the team at 2 to 10 people, though 21 members link themselves to the page.
