"We started the session with an loose idea of how we wanted to progress our marketing campaign and what industries we wanted to target. By the end of the meeting Jonathan managed to turn me away from what I thought was the quickest and most direct approach! and also made me see the size of the mountain we had to climb. Sensing me thinking ‘oh-my-god’ he ensured we had the bare bones of practical approach for the climb and also let me know that I was supported along this journey. Jonathan managed to ensure that the ‘fluff’ of marketing was distilled into actionable tasks and offered an approach not just ideas." Managing Director Systems company
