About Mark

I started my career building digital products in Santa Monica, California. In my 22+ years in the industry, I've scaled a social network to 20M users, grown a SaaS marketplace to $7M ARR, and helped 7,000 US hospitals adopt mobile messaging. Now I'm based in Barcelona, working with leadership teams across Europe and the US.

What I do
I help ambitious companies turn ambiguous product and AI opportunities into practical strategies, focused roadmaps, and shipped software. I do this quickly and without the overhead of a full-time hire. Comfortable in the boardroom and in the codebase.

- Grew a SaaS marketplace from zero to $7M ARR
- Deployed secure mobile messaging across 7,000+ US hospitals
- Secured $3M+ in growth funding at MeWe
- Cut cloud infrastructure costs 50% through the
- Built the first machine learning system to measure supply and demand on Amazon at scale

Where I focus right now
AI implementation for legal, finance, and B2B SaaS. I work on the strategy, the build, and all of the messy details in between. I help you cut through the AI hype to deliver measurable outcomes.

How we can work together

    I lead cross-functional teams based in the E.U. and the U.S., spearheading the evolution of MeWe to a product-centric organizational culture and development process. I actively engage in fundraising efforts, navigating conversations with both blockchain-focused and traditional "web 2.0" investors. I am the architect of the product roadmap, aligning it with our business objectives and customer's needs. I also oversee operational budgets, manage our subscription-based revenue streams, and create blockchain-based monetization strategies to drive innovation.
