Castletop Capital

Castletop Capital was established in 2000 by Mort Topfer. The family office manages wealth generated through his executive roles at Dell and Motorola. Alan Topfer and Richard Topfer serve as co-founders and managing directors alongside Mort. The firm allocates across real estate, private equity, and venture investments. Confirmed holdings include The Grove ATX mixed-use project, Grand Living at The Grove, Sunfield Development in Buda, Texas, and Center Point Mixed-Use Project in Wilmington, North Carolina. It also holds Falconhead Golf Club and properties on Rivercrest Drive in Austin. Geographic focus remains North America with emphasis on Texas markets. Investment stages span early and growth opportunities in sectors that include Healthcare Services, PropTech, and WaterTech. Deployment totals an estimated $250 million. The office maintains no disclosed additional locations beyond its Austin headquarters. Philanthropic activity centers on the Topfer Family Foundation. Richard Topfer holds an emeritus board role at HAAM. Mort and Bobbi Topfer support ZACH Theatre. No operational events from the last 24 months appear in available records. The structure ties directly to the Topfer family principals without external limited partners or third-party fund vehicles. This keeps decision authority inside the founding family and links capital deployment to the same operators who built the original Dell-derived wealth.
