Madrona Venture Group was founded in Seattle in 1995 by Tom Alberg, Paul Goodrich, Gerald Grinstein, and William Ruckelshaus, and built its identity around day-one partnerships it then holds for decades. The firm's own materials lean on Smartsheet, Redfin, Impinj, and Apptio as case studies in patient company formation rather than quick flips - a framing that fits a firm where more than 90% of investments were once concentrated in the Pacific Northwest. Madrona said it managed nearly $1.6 billion when Fund VII closed in 2018, and closed its largest fundraise yet - $770 million across Fund X and Acceleration Fund IV - in January 2025 to mark the firm's 30th year, now focused on applied AI, developer tools, cloud infrastructure, and AI-enabled biology.
