Management Team
  • Margaret Hartigan

    Chief Executive Officer
    and Founder

    Inspired to create a financial services site that not only addresses the primary needs of investors but also enables them to recast their relationship with money and investments in a manner they never dreamed possible, Margaret conceived Marstone.

    Prior to Marstone, Margaret was a top-quintile financial advisor for ten years in the Global Wealth Management Group at Merrill Lynch. Her practice was split between New York and San Francisco, and her clients comprised high net worth individuals and Fortune 1000 companies. Before she joined Merrill Lynch, Margaret was vice president of Strategic Relationships at MSI, Inc., a strategic consultancy whose clients included AT&T, T‑Mobile, and Florida Power & Light (FPL). Before MSI, she was a merchandising manager and early employee of myHomeKey.com, a San Francisco-based home services portal backed by KeySpan Corp., TXU Corp, and Bechtel Enterprises Holding, Inc.

    Margaret is a graduate of Brown University, a former trustee of Sonoma Academy in Santa Rosa, California, and an active leader in the alumni and major development efforts at Brown University and Phillips Exeter Academy.

  • Robert Stone

    Chief Creative Officer
    and Co-Founder

    Knowing that meaningful companies and products are built upon user-centered innovation, Robert teamed with Margaret to create a different kind of financial-services company—one that mirrors the relevance, the values, and the trusted experiences of other consumer brands we all know and use.

    Robert has been a creative director and graphic designer in San Francisco for over thirty years. In 1994, he co-founded Stone Yamashita Partners, a design-focused consulting firm that helps leaders and their companies define and navigate strategic change. Robert has worked within a broad range of industries to design product, culture, leadership, innovation, and brand experiences, for both corporate and consumer audiences. His clients have included Apple, IBM, HP, Wells Fargo Bank, Bank of America, Four Seasons Hotels, The Coca-Cola Company, eBay, The Gap, Levi Strauss & Co., PBS, Human Rights Campaign, and the San Francisco AIDS Foundation. His work has received awards in a number of design publications and organizations, including Communication Arts magazine, Print magazine, and AIGA.

    Robert received his BFA in graphic design from Art Center College of Design in Pasadena, California.
