OnDean

OnDean operates as a diversified platform that channels capital and expertise into various ventures, spanning technology, motorsports, and philanthropy. At its core, it functions as an investment vehicle deploying economic, human, industry, and social capital to advance its interests. Its direct investing arm, OnDean Forward, specifically provides operator-led capital to founders developing transformative products within the legal ecosystem and other regulated markets, offering hands-on support and strategic networking.

The firm was established by Andrew Sieja, the successful founder of Relativity, a prominent eDiscovery platform he launched in 2001. After building Relativity, Sieja leveraged his entrepreneurial success and insights to create OnDean as a family investment office. This initiative was born from a desire to apply his experience and capital to cultivate ventures that drive progress and strengthen communities, extending beyond his initial entrepreneurial endeavors.

OnDean's efforts primarily benefit founders of innovative technology companies and social entrepreneurs. OnDean Forward supports those creating solutions for legal and regulatory tech, while its philanthropic arm, Alta Futures, empowers social entrepreneurs tackling challenges in climate, democracy, and community. The overarching vision is to cultivate a lasting legacy of impact by fostering ventures that ignite adventure, propel innovation, and enrich the communities it touches.
