About
Sievert Larsen Family Office is a Miami-based multi-family office providing investment management and advisory services to ultra-high-net-worth families. The firm specializes in alternative investments, with a strategic focus on venture capital, private credit, and real estate opportunities. As a multi-family office model, Sievert Larsen serves multiple family units seeking professional portfolio management and investment advisory services rather than operating as a single-family vehicle. The firm positions itself within a competitive landscape of established multi-family offices such as The Family Office Group (Greenwich, Connecticut) and Lazard Family Office Partners, which similarly target ultra-high-net-worth clients with outsourced investment management capabilities. The alternative investment focus—spanning venture capital, private credit, and real estate—reflects broader institutional trends in family office asset allocation, where traditional equity and fixed income allocations are increasingly complemented by illiquid, higher-return strategies. While specific check sizes, portfolio composition, and individual fund commitments remain proprietary, the Miami location provides access to growing venture ecosystems in South Florida and Caribbean investment opportunities. Family offices operating in this segment typically provide members with professional due diligence, deal sourcing, portfolio construction, and ongoing asset management oversight. For family stakeholders, this model offers institutional-quality investment processes without the overhead of building independent investment teams; for fund managers and operating companies, multi-family offices serve as committed capital sources willing to participate in larger rounds and follow-on investments. The firm maintains an active web presence at sievertlarsen.com, indicating ongoing business development and investor engagement.
