Summation is building the future of business planning and analytics by bridging the gap between data and decision-making. We empower organizations to transform complex data into clear, actionable insights that drive business outcomes. Our AI-native platform integrates advanced data models with intuitive workflows, making enterprise performance management simple, collaborative, and effective. We are looking for a Founding Marketing Manager with 4–6 years of experience in product marketing, marketing strategy, or related roles. As the founding member of the marketing team, this person needs to be a builder—helping us develop the marketing function from the ground up, scaling repeatable marketing operational processes, and implementing the right business systems, tools and workflows. This role is ideal for someone who enjoys being hands-on across marketing channels, analytics, and strategy, and who thrives in early-stage environments where experimentation, learning, and iteration drive impact. You’ll work directly with the Executive team, Head of Business Operations, while partnering closely with Sales, Product, and Design.
