Founding Marketer/Head of Growth
Mage Legal
About Mage Legal Mage Legal is an AI-native legal technology company built for M&A, PE, and corporate legal teams. Our platform automates core diligence workflows—issue spotting, disclosure schedules, first‑pass diligence outputs—used in live, high‑stakes transactions. We’re scaling adoption inside law firms and funds, testing distribution channels, refining our positioning, and building the legal AI experience attorneys actually trust under deal pressure. Who We’re Building For (ICP) Deal attorneys, PE professionals, and in‑house legal teams working on fast‑moving M&A and growth transactions. Typically Big Law, elite performers, highly analytical, and extremely risk‑sensitive. They care about accuracy, auditability, and credibility more than novelty. They’re skeptical of “AI for law,” pressed for time, and allergic to tools that create cleanup work. Your work will shape how this audience discovers Mage Legal, evaluates it, and ultimately trusts it enough to use on real deals. What You’ll Do At Mage Legal, every team member can propose an experiment. You’ll help shape hypotheses, contribute your own ideas, and turn them into live tests across acquisition, activation, and workflow adoption—always grounded in real attorney behavior. Hypothesis - Launch - Measure - Iterate Design and run growth experiments across channels relevant to legal buyers (founder‑led sales, referrals, content, partnerships, targeted outbound, events, and communities). Test and refine positioning, messaging, and offers that resonate with law firms, PE funds, and in‑house teams (e.g., pilot structure, deal‑based pricing, PoCs, workflow entry points). Collaborate with engineering to spin up lightweight demos, onboarding flows, and workflow experiments for rapid testing inside real diligence scenarios. Translate insights into product and GTM improvements, working closely with product and design to bake winning workflows into the core platform. Must‑Haves Background in B2B product experimentation, developer tools, legal tech, fintech, or other high‑trust enterprise software. Proven ability to design, launch, and analyze experiments across non‑consumer channels with long sales cycles and high credibility requirements. Strong grasp of analytics, funnel design, and qualitative signal; able to combine data with real customer conversations. Deep curiosity about professional workflows, incentives, risk tolerance, and what drives adoption in conservative, high‑stakes environments. Excellent communication skills; able to translate messy signals into clear recommendations for product, sales, and leadership. You take the work seriously and aim for excellence, but bring energy, creativity, and zero pretense—we move fast, test often, and care deeply about quality. Nice‑to‑Haves Experience selling to or working with law firms, PE, or enterprise professional services. Familiarity with M&A workflows, diligence processes, or legal operations. Experience shaping early‑stage positioning, pricing, or pilot programs. Previous startup or early‑stage experience wearing multiple hats. Why You’ll Love Working Here High‑velocity culture: Ideas ship quickly; experiments run in days, not quarters. Real stakes: Help shape AI systems used in live deals where accuracy and trust matter. Clear product‑market signal: Strong pull from sophisticated legal buyers who feel today’s tools don’t work. Tight founder collaboration: Work directly with the founder building and deploying the product. AI‑first from day one: No legacy constraints, no “AI wrapper” thinking—this is infrastructure, not add‑ons.
