Single-Family Office with Background in Healthcare & Technology

Our Story

AssetBlue Investment Group is a single-family office founded in 2016 by Mark and Nasrin Thierer. As experienced entrepreneurs and operators, Mark and Nasrin enjoyed successful careers as executives in the healthcare and technology industries, respectively. They each guided their companies to successful exits and subsequently founded the family office and Thierer Family Foundation.

AssetBlue Investment Group oversees a diversified investment portfolio of public and private investments and serves as the Accounting, Finance, HR, and Management arm of the family’s various businesses and philanthropic efforts. It also serves as the “incubation hub” for new business opportunities where the family takes a control position.

Our Businesses & Interests

Thierer Family Foundation’s mission is to increase the impact of nonprofits in the fields of food insecurity, shelter & human services, and arts & culture by helping them leverage technology to be more effective, efficient, and sustainable.

Mark and Jonathon Thierer partnered to co-found Waltz Health, a digital health company in the pharmaceutical space. With a senior team of industry veterans and backing from leading venture firms including Google Ventures, Waltz seeks to fundamentally rewire the pharmaceutical supply chain, improve pricing transparency, and lower drug prices for all.

After years of partnering with and building technology for food banks and pantries, Nasrin Thierer founded and launched Vivery technology to equalize access to nutritious food and other food services for everyone, regardless of location or circumstance.

Vivery Community is a public charity established by Nasrin Thierer to scale access to nutritious food and benefits by providing Vivery technology to every food bank and pantry at no cost. In addition, Vivery Community partners with local communities and organizations to fund innovative food access programs.

Areas of Focus

AssetBlue Investment Group makes investments in diversified industries including healthcare, technology, food, aerospace, retail, and real estate, among others. A small team of experienced entrepreneurs, operators, and investors, AssetBlue is a “best ideas” investment group and won’t turn down a great opportunity to satisfy a specific asset class percentage target. We concentrate in what we know and diversify in what we don’t.

We invest in the following ways:


We believe in the long-term growth of public markets and are fundamentally multi-generational investors. Investing across a variety of sectors and geographies, we access the public markets primarily through low-cost, passive investments with an active management overlay.


With patient capital, we believe in the ability of certain sectors and managers in private markets to outperform their public counterparts over time. We seek top-tier fund managers focused on Venture Capital, Growth Equity, Private Equity, Private Credit, and Real Estate & Infrastructure.


Entrepreneurs at heart, we support business builders at all stages of growth both professionally and personally. Our strong relationships with Fund managers often lead to Direct and Co-Investment opportunities with companies and visionary founders who are solving important problems in our industries of focus. Investments are made as early as Seed Stage and grow alongside the businesses and entrepreneurs.
