The SGL Way
Investing On Our Terms
We bring seasoned and extensive experience to investing, managing assets, and running a family office. We’ve amassed the means to champion innovators who share the values of the SGL collective by stewarding the resources for which we’re responsible.
In doing so, we work toward an economy of service tied together by bold, impactful ideas and leaders with the vision and tenacity to pursue them.
We believe the best way to model effective leadership is to serve.
How We
Serve
In Pursuit of Ideas With Impact
At SGL, we invest the resources entrusted to us—time, capital, talents, expertise, connections, and more—to serve exceptional leaders and their extraordinary endeavors across both for-profit and not-for-profit sectors.
Impact takes precedence, and that looks different for every investment: in some cases, profitability; in others, mature governance, measurable progress, optimized performance, resilience of the organization, or strength of the culture and leadership.
