I help B2B SaaS teams improve activation, fix funnel drop-off and set up growth systems.
I have advised 35+ founders and delivered measurable results including a 25% sales uplift, 5% regional revenue growth across a franchise network, 40% conversion improvement, over £5M influenced in annual pipeline value, 2,300+ acquisition clicks, 11.4% paid media CTR, 40%+ email open rates, and 14K followers grown in 2 weeks through positioning and organic traction.
I usually work in focused 90-day engagements designed to diagnose the real bottleneck and create a stronger growth path before execution becomes expensive.
My background includes leadership roles with global organisations including Metro Bank and Donna Karan New York. I hold a Master’s degree from a leading European university, I’m the author of Why Customers Choose and my work has been featured in Bloomberg Terminal and AP News.
