Senior practitioners. Named. Photographed.

Mark founded Demand Spring in 2012 on a simple conviction: B2B marketing works when strategy and execution are run by the same senior people. Over 15 years he has grown the firm into a revenue marketing consultancy trusted by enterprise B2B brands.

He was an early voice on operationalizing AI in marketing, and he writes regularly on the craft and the future of revenue marketing. As Executive Chair he sets the firm’s direction while its managing directors run day-to-day delivery.

Jonathan leads applied AI work inside client engagements, building the workflows that take repeatable tasks off marketing teams. He pairs deep martech experience with a practical read on where AI genuinely earns its place.

Erin leads Demand Spring’s own marketing and owns the firm’s methodology, the single system every engagement runs on. She joined to bring a practitioner’s discipline to how the firm goes to market and how it codifies what works.

She has spent her career in B2B demand generation and marketing leadership, and is a frequent contributor on revenue marketing and practical AI adoption.

Derek oversees client delivery across Demand Spring’s four practice areas. He makes sure the senior practitioner who scopes an engagement is the one who runs it, so what a client is sold is what a client gets.

He has led complex B2B marketing and martech programs for enterprise clients for more than a decade.
