Darren Stewart is the Founder and Director of Team4, a London-based B2B SaaS marketing agency building AI-powered Inbound Engines for software companies that want compounding organic growth.
He specialises in mid-market SaaS businesses operating in niche industries, where precise positioning and category ownership matter more than volume tactics. Over his career, Darren has helped SaaS companies grow inbound pipeline from zero to millions in qualified revenue. His clients have included Peoplevox, a warehouse management SaaS acquired by Descartes for £19 million, and Forecast, an AI-powered project management platform acquired by Accelo in 2025, alongside a range of fast-growing SaaS businesses across construction tech, carbon accounting, document management, and HR software.
His methodology, the Inbound Engine®, is a registered framework built around sustainable acquisition rather than paid dependency. Darren is also the founder of SaaS Hackers, a publication and practitioner community covering B2B SaaS digital marketing, and a finalist at the European and UK Search Awards.
