Thematic Aerial and Related Mobility Businesses

Changing mobility economics changes lives. Advanced aerial mobility will accelerate market growth by substituting car and truck trips with air trips. This growth will give new customer groups access to rapid, low cost transportation and thereby enable economic development of isolated regions, improve the availability of affordable housing, and eliminate carbon emissions. Along the way, the companies that pilot this journey will develop new technologies that will also accelerate other mobility sectors.

We see investing in advanced aerial mobility as an extension of our journey with Volaris.
Volaris developed new, underserved markets and grew them dramatically by providing low-cost, point-to-point air transportation. This strategy helped to triple the size of the Mexican aviation market over time.

Transformational Market Stimulation

Our unfair advantage comes from our unique expertise linking industry and business economics to stimulation strategies to grow markets.This helps us create specialized investment theses with the potential for differentiated returns.

We look to place capital with companies who catalyze growth. Sector competitiveness vs. automobiles, need for platforms in certain elements of the advanced aerial mobility value chain, choke points in the value chain with limited competition, and defensibility based on patents and certification all play a role in our thinking about where the capital we manage will find the highest returns.

Tomorrow and Today

We focus on companies that benefit from these technology trends and serve existing markets. We like to focus on investments where new technologies stimulate demand based on products that immediately offer a lower cost than their substitutes and have a long-term upside from new use cases.

DiamondStream Partners looks to help mobility founders transform their rough diamonds into fully cut gems. We primarily target middle-stage companies in the US, Europe and other English speaking countries that fit with our thematic focus. This includes aerospace companies, aviation related companies, hardware, and software companies. By building the future through the present, we connect more dots and create great returns for investors.
