S 02 | Ep 6 From Churn to 95 % Retention : The New Agency Growth Playbook Luke Tobin is a serial entrepreneur who has exited three companies , including Digital Ethos , the UK ' s fastest growing marketing agency , which he sold to Cadastra . As co - CEO of Cadastra EMEA , he oversaw 900 employees and a 50 million dollar revenue portfolio with clients including Samsung , Unilever , and the NHS . He now runs Tobin Capital , a firm focused on scaling high - potential businesses with a portfolio that includes SpaceX . In this episode , Luke traces his path from founding an agency on a deeply integrated client model to scaling it internationally across Germany and Canada , and eventually into an investor and advisor role . He argues that in a commoditized market , the relationship between agency and client is the real differentiator , and that most agencies avoid the frank conversations that would actually build trust and drive long - term retention . He also shares his approach to pitching , including the value of personalization and simplicity in standing out against a sea of identical PDF proposals . Beyond business , Luke opens up about the pattern he has noticed across his own exits and those of other founders . Financial success and milestone achievements tend to raise more questions than they answer , and purpose rarely arrives automatically on the other side of an exit .
