Our purpose is properties.

Convexity is a full-service real estate investment firm. As part of DRW, our mission is to invest in properties and projects where our flexibility, insights and expertise can create significant value.

With no outside investment or influence, we seek challenging projects that can benefit from our agility and sky-high standards.

We’re natural leaders.

We have the vision for what’s possible and the expertise to execute it, from large-scale projects to more bespoke opportunities. Our goal is for every project we touch to reach its highest and best use.

Community matters.

The projects we invest in don’t exist in a vacuum—if they did, there wouldn’t be much point. We work closely with local governments and communities to ensure our vision matches theirs.

So does experience.

Our in-house expertise and seasoned perspective allows us to offer fresh, unique opportunities while staying true to the realities of the market and the surrounding community.

We’ve assembled a purposeful portfolio of properties throughout the United States and beyond.
