I started in B2B data at Leadspace, where I grew from managing an analyst team to running product for the data platform. Then Oracle — Principal PM on the largest portfolio in the Eloqua organization, leading cross-functional initiatives across four offices and winning the Rookie Award.

From there I moved to Wesana Health as Head of Product, leading strategy and development for the Psytech platform after its acquisition in 2021. That's where I learned what product rigor looks like in a regulated, high-stakes health tech environment.

Since then I've been consulting independently — serving clients including MAPS Israel, Plaza Ventures, and Elementary Data — and most recently served as Head of Product at NatureX RMS, a parametric insurtech platform for the $154B nature-based solutions market. I also co-founded the Nature Tech Collective.

I take on product strategy and execution work across three domains I know well. Clients range from early-stage startups to established organizations navigating new markets.
01
Nature Tech
Conservation technology, parametric insurance, climate risk, regenerative agriculture. I've been Head of Product at a nature data insurtech and built community infrastructure for the sector.
02
Health Tech
Psychedelic-assisted therapy, clinical workflows, patient-facing platforms. I've led product through an acquisition and scaled clinical tools in a rapidly evolving regulatory landscape.
03
Enterprise SaaS
Marketing automation, data platforms, B2B tooling. I've managed large product portfolios at Oracle and built data products from the ground up at Leadspace.

Independent product and strategy consulting for clients including MAPS Israel, Plaza Ventures, Elementary Data, Prof of Wall Street, and a private aquaculture search fund. Engagements ranged from product strategy to go-to-market and data architecture.

Based in central Greece. Summers in Canada. Outside of product work, I spend time on permaculture, land-based education, and building a low-footprint home with my family.

Permaculture

Designing and building a low-footprint home on land we're restoring. Food forests, water systems, and soil building in a Mediterranean climate.

Education

Co-running a permaculture education site with my wife and Greek nonprofit Ecogenia — an education hub for low-input, resilient agriculture in the Mediterranean.

Mountains

Hiking, backcountry camping, and time in the mountains — both in Greece and in the Canadian wilderness every summer.

Also a
musician.

Music has been part of my life as long as anything else. I write and record — it doesn't fit neatly alongside the rest of what I do, which is probably why I keep doing it.
