If you scale a bootcamp, online-course platform or continuing-education programme in the UK market, you know the double burden: the ad cost of winning one enrolment — known in marketing as enrolment CAC — rises every year (for bootcamps typically between £700–£2,200), and at the same time every course start (each new cohort) runs on an 8–12 week cadence with its own marketing push. You don't have one campaign per year, you have 4–6 parallel mini-launches.
Plus: you don't sell software, you sell a career decision. Long consideration time, lots of comparing with competition (General Assembly, Le Wagon, Makers etc.). Your audience needs evidence — alumni stories, job-outcome data, credible instructor profiles. Generic stock-photo marketing doesn't perform.
