15+ years inside the energy industry.

I’m Kerri Ryan — a fractional CMO specializing in B2B marketing for clean energy and cleantech companies. I’ve spent an entire career at the intersection of complex technology and the markets that buy it.

My energy career took shape at SCHLUMBERGER (SLB), where I learned how energy technology actually gets sold — not through clever campaigns, but through technical credibility, relationship-driven sales, and messaging that earns trust from engineers and procurement teams alike. That foundation shaped everything I’ve done since.

Over a 25-year marketing career, I’ve worked as an in-house marketing leader at large energy enterprises, a partner in a marketing agency, and an independent consultant. Most recently, I led marketing for companies in the green hydrogen space — navigating policy-dependent markets, multi-stakeholder sales, and buyers who needed to be educated before they’d buy.

Those are the exact dynamics facing today’s fastest-growing clean energy sectors. The technology is different; the go-to-market challenge is the same.

I’m not a generalist marketer who "also does energy." I’m an energy industry insider who happens to be a marketer.
