Tawni Nazario-Cranz

Tawni L. Nazario-Cranz is an operator-turned-investor and company builder at scale. She is currently an Operating Partner at SignalFire, where she helps lead post-investment strategy from pre-seed through Series D+. Since 2017, she has partnered with founders to connect strategy, capital, and operating systems—spanning GTM, product cadence, org design, and financial discipline—to turn early momentum into durable enterprise value as companies grow from first hires to global scale. Before venture, Tawni spent a decade at Netflix powering its transformation from DVDs to streaming and its global breakout. During her tenure, Netflix went from zero streaming subscribers to 100M+, and from ~$1B in DVD revenue with no streaming revenue to more than $10B in global streaming. She co-authored the Netflix Culture Deck and helped prove that Talent Density accelerates execution, the essential ingredient for a high-performance startup. That experience informs how she helps founders keep operating models simple, feedback loops tight, and resource allocation disciplined. Outside of venture, Tawni and her family are building Nazario Ranch Vineyards in Saratoga, CA. She holds an EMBA from the Drucker School and a BA from UC Santa Barbara.
