Hallam

Based in London, this agency focuses on B2B digital marketing, working with organisations across sectors including B2B SaaS, clean energy, education, healthcare, HR software, professional services and manufacturing. Client testimonials referenced on its site include Lattice, Workbooks, Hitachi Solutions, Infodesk and Holcim UK, indicating experience with mid-size to enterprise B2B brands looking for long-term marketing partnerships rather than one-off projects. The team size sits between 11 and 50 people, and the agency positions itself around combining brand-building with performance marketing for measurable, commercially-driven outcomes. Services span brand work (creative campaigns, brand strategy, brand identity), reach-related activity (digital strategy, paid media, organic search, AI search, account-based marketing, digital PR, content marketing), experience design (web design, UI/design systems, web development, conversion rate optimisation) and data services (reporting, analytics, testing and measurement). A named diagnostic framework, Elements, is used to assess what is and isn't working for a client's B2B performance and to identify routes to stronger commercial results. Case studies described include a brand transformation for SaaS company Infodesk, a high-performance website build for Hitachi Solutions, an award-recognised campaign for CRM provider Workbooks, and brand development for cybersecurity company CovertSwarm. The agency also runs Better B2B, a community aimed at B2B marketers.
