Founding Marketing Lead

About MarbleMarble is building the new operating system for youth mental health by connecting schools, therapists, and health plans on a single platform to unlock access to care today and raise the standard of care for tomorrow.Last year, 1 in 10 teens attempted suicide. At the heart of this crisis is a severe lack of access to quality, affordable care. When kids can't get help, problems compound and preventable tragedies follow. Marble partners directly with school counselors to get students into care quickly by connecting them to licensed therapists through the insurance coverage they already have, with no waitlists.We're an early-stage, fast-moving team. The people who join now will shape how we build and what we build.About The RoleWe have channels that are working — cold outreach to counselors, staff workshops — but they have room to grow. You'll take ownership of them, make them perform, and expand into new territory: ed tech partnerships, direct acquisition, and beyond. You'll set clear success metrics before each experiment, analyze results rigorously, and make fast, well-reasoned calls on what to scale.This is Marble's first marketing hire. You'll build the demand gen foundation that drives school partnership growth by getting into the details, moving quickly, and taking full ownership of what you ship.You'll sit at the intersection of growth and execution, with a direct line to leadership and a mandate to build the marketing function from scratch.What You'll DoOwn and optimize existing growth channels, including outbound email to school counselors and staff workshop programsDesign and run experiments on new acquisition channels — define the hypothesis, set success criteria upfront, analyze results, and scale or kill accordinglyBuild the sequences, messaging frameworks, and targeting infrastructure that make outreach repeatable and scalableExplore new channels (ed-tech partnerships, paid acquisition, referral programs, and others) and build the investment case for what worksManage contractors and external vendors to extend capacity without adding headcountTranslate channel performance into clear recommendations for where Marble should invest nextWho You Are6+ years of experience in growth, demand gen, or early-stage marketing, with meaningful time at a startup where you built something from scratchYou've been an early or founding marketer before, or played a comparable 0-to-1 role and have results to show for itYou understand SMB and mid-market demand gen: the channels, the unit economics, and the trapsAnalytically strong.
