Summary
🤩
Rockstar🎓
Top SchoolJack Sellwood is a product-focused technologist and founder with nine years of experience building developer and data-first products, now leading Grapple as cofounder and CEO to create a DIY data platform for finance and sales teams. Previously he shaped GraphOS Cloud and developer tooling as Staff Product Manager at Apollo GraphQL and drove CMS integrations and content workflows at Gatsby, bringing deep experience at the intersection of developer experience and content/data systems. He combines design-minded minimalism with a penchant for "tidying up technology," favoring simple, usable solutions over unnecessary complexity. Based in Omaha, Jack blends startup grit from founding WEDGE with product leadership across fast-moving teams, and he’s particularly effective at turning developer tooling and publishing challenges into polished, adoptable products. An entrepreneurial builder who still delights in hands-on design and tooling details, he’s as comfortable sketching UX flows as prioritizing API and platform roadmaps.
