I wrote the go-to-market playbook that gave B2B SaaS its growth benchmark — triple, triple, double, double, double. I coach the founders and marketing leaders applying it.

A serial entrepreneur and marketing leader, Stijn has contributed to the success of 20+ startups as a C-level executive — Chief Revenue Officer of Acumatica, CEO of MightyCall, and the initial global go-to-market for Atera, a B2B SaaS unicorn. Before startups, he led global SMB marketing and B2B product marketing for Microsoft's Office platform.
He wrote T2D3, co-founded Kalungi — the agency that pioneered the fractional CMO model for software companies — and has built or audited go-to-market for 100+ B2B SaaS companies between $0 and $50M ARR, hiring and coaching dozens of CMOs along the way. Today he builds T2D3 OS, where AI agents and human experts do the work of a marketing team together.
Stijn brings that experience to keynotes, hands-on workshops, and team and executive coaching engagements.
Every engagement installs the same method. What changes is how much of the work Stijn owns.
