spent the last decade building growth systems for b2b and prosumer companies. from zero to millions in revenue and fundraise. my own companies. my clients’.
↗ what i own, and how i run it
i own the function end to end.
positioning, messaging, product marketing, lifecycle, customer marketing, the team and the budget behind it.
what’s different is underneath. i build growth as engineered systems, not campaigns: one shared data layer where every customer, every reply, every click is a stored fact. the engines read from it before they act and write back after. so next month’s campaigns start knowing more than this month’s did.
that compounds: retention, adoption and advocacy carry the acquisition curve instead of linear paid spend.
↗ the engine, in one page
three engines, one shared data layer.
one lead, one flow
growth engine
knows the lead, the pain, the channels that work per person
content engine
writes narratives per ICP and channel
design engine
ships every format: email, DM, InMail, ad, retargeting, video
feedback
every reply lands in the shared data layer as a fact

Named one of 30 Global Founders to Watch.
By Aspire, in collaboration with Lightspeed Venture Partners and Deel. The cohort recognises founders who crossed borders to build in the US and are now redefining what’s possible.
the last two years i went deeper on the technical and engineering side.
i run my own company as queryable code. an ontology of every customer, machine-enforced rules, agents that source, score and route, governance that blocks bad data at commit time. same discipline applied to the growth stack itself: attribution, martech ops, data model, funnel eng.
