Aaron Hauge
Founder & Chief Executive Officer
Aaron Hauge's career spans nearly two decades across real estate development and business growth, beginning at Artspace Projects — the nation's leading developer of real estate for the arts. He has consulted on over 150 real estate development projects worth more than $3 billion across the U.S., has been involved in real estate assets totaling more than $3.5 billion in combined value, and has generated over $6 billion in revenue for clients across all engagements.
Beyond real estate, Aaron has helped a client grow from $3M to $20M in annual revenue within 12 months, boosted a startup's valuation from $60K to over $100M in 24 months, and generated over $200M in new B2B revenue for partnered companies — yielding an average of 400% year-over-year growth. He founded Leasing Pros, which has leased over 15,000 multifamily units across 17 states, leads Veritas Ventures alongside partner Tom Noordijk, and serves on the board of Endurance Exteriors as a strategic consultant and investor.
