If you're scaling as a B2B SaaS founder in the UK market, you know the performance-marketing pain: LinkedIn CPMs — the price per 1,000 ad impressions — sit at £20–£35 for most UK B2B campaigns. Meta is too broad — you pay for every passer-by. Google brings leads that look good on paper (MQLs), but only 8–12% turn into real sales opportunities (SQL conversion). Your sales team spends half-days on unqualified demos.
At the same time you don't have one target group, you have 3–5 concrete ideal customer profiles (ICPs, as marketers call them) — CTOs, Heads of Operations, VPs of Sales — each thinking differently, deciding differently, buying differently. Generic advertising hits nobody right. You need persona depth, not demographic clusters.
