Alder Companies
Alder Companies was established in 1986 by Don Sturm. His wealth originated from community banking acquisitions, real estate development and diversified private investments. The firm remains a single-family office serving the multigenerational Sturm family. Alder Real Estate acquires, develops and manages properties across Colorado and the Rocky Mountain West. Alder Ventures deploys committed capital into venture and private equity opportunities. Confirmed co-investments include AMP Robotics alongside Sequoia Capital, GV and Wellington Management. Geographic reach covers North America, Europe and Asia. Investment stages span early-stage venture through buyouts. The firm maintains three family foundations. No additional offices outside Denver are recorded. No operational events from the last 24 months appear in available sources. Alder Companies keeps all investment and real estate activity inside two family-owned platforms. This internal structure removes external GP relationships for core deployment.
