About JD Deitch

JD Deitch

I've spent 20+ years building, scaling, and integrating B2B SaaS, data, and tech-enabled services businesses at their inflection points, through rapid growth, M&A, post-deal integration, and restructuring.

Across those years, my executive roles have covered GTM, operations, product, and HR in founder-led startups, PE-backed growth companies, and public companies. Two of them exited — one by acquisition, one by IPO — and I've led three post-merger integrations ranging from $29M to a $1.1B acquisition.

Experience has taught me that great execution is what separates the companies that succeed from the ones that don't. Even with great strategy and a clear vision, most companies struggle to translate plans into results, especially when conditions are uncertain or the organization is in flux. That's where I've built my career.

For the past two years I've been running Passaggio Advisory, working with B2B SaaS CEOs and investors on what they're building next: AI-era strategy, operating models, and product. I'm now looking for a full-time CEO, C-suite, or PE operating partner role to do that work end-to-end.

I'm based in Paris, travel frequently to the US and UK, and hold dual US/French citizenship. I have a PhD in political science with a research methods focus, which shows up in how I approach problems. Outside of work, I chair the 100k+ member Manchester United Supporters Trust and, as time and family allow, follow the team home and away.

What's Next

I'm open to CEO, C-suite, or PE operating partner conversations in B2B SaaS. Based in Paris, I work across the US, UK, and EU.
