Founding Customer Success Manager at Allegrow
Every B2B sales team is facing a deliverability crisis as AI scales, and Allegrow is the mission-critical solution ensuring emails hit the inbox. We’re looking for a Founding Customer Success Manager to own the US market, build the CS playbook from scratch, and manage a $1-2M ARR book. Reporting directly to the CEO, you'll have the autonomy to shape the post-sales function at a venture-backed startup already trusted by public tech giants. If you have 2-7 years of SaaS experience and love building from zero, this is your chance to define success at a high-growth company.
