S7E11 - B2B SaaS Growth Strategy 2026: Scaling with AI Agents & Growth Loops With Mark Appel

Recorded live at the SaaS Summit in Amsterdam, this episode of the Grow Your B2B SaaS Podcast dives into a focused conversation with Mark Appel, Chief Marketing Officer at Sendcloud. As one of Europe’s fastest-growing B2B SaaS platforms, Sendcloud operates across eight European markets, generating close to 60 million in annual recurring revenue with a team of about 450. In this discussion, Mark reveals how Sendcloud approaches international scaling, builds cross-functional go-to-market alignment, identifies and prioritizes compounding growth loops, and integrates AI agents across marketing and GTM operations. He also reflects on what he would do differently if he could rebuild a SaaS go-to-market motion from scratch, what early-stage founders should focus on to reach their first 10K MRR, and how to evolve from feature-led messaging to a brand-led narrative on the path to 10 million ARR.
