B2B SaaS demand-gen agencies typically charge between £3,000 and £45,000 per month depending on company stage and scope. Early-stage Series A companies often start at £3,000–£5,000, whilst mid-market and enterprise operations usually invest £20,000–£45,000+ monthly for full-service or fractional CMO models.
GrowthSpree (£3,000/month), Directive Consulting (£5,000/month), and Powered by Search (£5,000+/month) are most accessible for Series A founders. These agencies specialise in pipeline-first approaches and offer entry-level retainers suitable for companies with ARR below £5 million.
B2B SaaS demand-gen agencies specialise in pipeline acceleration, revenue attribution, and dark-funnel measurement rather than vanity metrics. They use proprietary methodologies (Demand Gen 2.0, Customer Generation, Omni OS), integrate RevOps and CRM data, and prove marketing impact directly to revenue.
