Sterling Witzke leads all private investments for the Winklevoss family office with an unusually broad early-stage mandate spanning both traditional tech and crypto while maintaining a concentrated 85-company portfolio, giving her a cross-sector view across SaaS, e-commerce, IoT and crypto-native ventures. As a former founding team member and Chief Business Development Officer at Turo, she brings hands-on marketplace scaling experience to her investing, and she looks specifically for crazy yet coachable CEOs—founders bold enough to believe they can change the world but self-aware enough to ask for help where they lack expertise.

• Deeply invested in the crypto and Web3 infrastructure space, with a specific interest in how regulation and proper accounting can legitimize the industry. She frequently highlights the necessity of clear financial standards for digital assets, often pointing to the solutions provided by her portfolio companies that help businesses manage crypto accounting and taxes.
• Champions a hard-working builder mentality, encouraging founders to focus on product development and innovation regardless of market conditions. She often uses her platform to amplify product launches and milestones for her portfolio companies, such as celebrating a startup that is shaking up the television and advertising markets or another that helps freelancers build wealth.
• Places a high value on genuine customer service and animal welfare, showing a soft spot for brands that treat users with empathy. A strong example of this is her praise for an online pet retailer that sent flowers to her family after a pet passed away, which she cited as incredible service that earned her loyalty.
• Advocates for the stability of the technology ecosystem, particularly regarding the banking partners that support startups. She has expressed strong opinions on the importance of protecting the financial backbone of Silicon Valley innovation to ensure that bailouts and financial support are applied consistently rather than arbitrarily.
• Enthusiastic about the intersection of gaming, the metaverse, and digital collectibles. She closely follows the technical execution of NFT projects and virtual world expansions, occasionally commenting on user experience issues like high transaction fees or minting mechanics during major digital asset releases.
