I build growth engines and customer lifecycle programmes across B2B, B2C, and subscription businesses.
What I'm looking for
I've led growth and customer lifecycle work across Thinslices, Xebia, PropertyBox, and subscription businesses, connecting marketing, sales, and customer success from demand generation through retention and renewal.
At Thinslices, I led UK demand generation and ABM strategy, increasing ICP engagement by 50%. I also delivered a brand refresh and website redesign that lifted website engagement by 40% and lead conversion by 25%.
At Xebia, I built multi-touch HubSpot ABM programmes for priority enterprise accounts and achieved active engagement with 80% of the target cohort. At PropertyBox, I increased qualified leads by 45% and helped simplify B2C onboarding, reducing customer acquisition costs by 20%.
I've supported market expansion into Brazil and Latin America, built bilingual cross-functional teams, and worked across CRM, onboarding, paid acquisition, SEO, lifecycle email, and subscription growth. Most recently, I led a six-person team implementing integrated security technology systems across client, contractor, and technical stakeholders.
