Julien de Waal is a CMO and growth marketing leader who builds AI agent systems. Also an electronic music artist, Jax Lukken.
Hello. I'm a CMO who builds. I've led growth and marketing teams at high-growth fintech and crypto companies, and I build the AI agent systems that power them: content, video, distribution, lead generation. I also turn feelings into music as Jax Lukken. If you're building something that matters, let's connect.
Listen to Jax Lukken ↓CMO, VP Marketing or Head of Growth, full-time or fractional. 16+ years across crypto, fintech and consumer apps. At SwissBorg I ran a CHF 1M+ budget at 3 to 4× ROAS with 12 direct reports, and took app installs from 600 to 25,000+ in 3 months.
Talk about a role ↗AI agent systems for content, video, distribution, lead generation and marketing automation. I prove them on my own products first: the multi-agent pipeline behind Sonscape cuts 40+ hours of video production to under 1 hour, for under $100.
Scope a build ↗Multidisciplinary. Multicultural. Full-stack entrepreneur. I create things that didn't exist before I needed them: companies, systems, music. All born from the same restless belief that if it's broken, build something better.
I've led growth at a European crypto scale-up, run a startup incubator, founded multiple startups and built AI agent products from scratch, all while releasing music independently. The thread running through all of it: creativity meeting systems.
He's the kind of person who can step into almost any role the company needs and still deliver great results. To maintain that level of quality in such a fast-paced environment, where even a single role is demanding, is honestly impressive. But what sets him apart in my eyes is his emotional intelligence; he's a genuinely caring person who has a natural knack for understanding and connecting with the people he works with.
Julien did a solid job managing the website team at SwissBorg. He played a key role in overseeing SEO efforts and ensuring the web platform remained stable and optimized. He is a reliable lead who understands the technical demands of a high-growth fintech site.
Julien proved an exceptional product and growth manager. He has an exceptional ability to bring clarity and relatability to complex and technical products. I witnessed Julien bring impactful change to our web app — from UI improvements to technical SEO which saw a big uplift in inbound traffic, to delivering a fully polished desktop version of our mobile investment app in a matter of months.
Julien is clearly one of the best talent I met in the innovation/startup/disruption sphere. He is deeply multi-skilled, straight to the point, results driven, speaks several languages as if he was native. He is also driven by strong human values and a capacity to think out of the box.
Julien was instrumental in helping to re-align HIPs in 8 mostly autonomous offices around a central vision and operational methodology. Julien is thoughtful, well-reasoned, and highly capable. I strongly recommend Julien and know any project he works on is better off for his involvement.
From my earlier startups, where I combined COO and CMO roles, leading operations, marketing and growth.

Music has always been where the things that don't fit anywhere else finally find a home. Poems at 15. Lyrics through challenging times at 16. Years of making music in private. Fear of judgment keeping the drawer closed. Then one conversation changed everything. The week after: first release. The flood gates opened. Two albums. Twenty songs. Globally distributed.
