I help B2B SaaS teams improve activation, fix funnel drop-off and set up CRM and lifecycle systems. Hands-on execution across HubSpot, email flows and onboarding.
I have advised 30+ 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 2–4 week 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.

During the trial, we’ll have an initial call to understand your context, current challenges and what’s not working as expected.
