Frank Greeff is a former chef-turned tech entrepreneur, keynote speaker, and philanthropist. He is most famous for co-founding real estate platform Realbase with his 2 brothers, and at just 29 years old, they sold it to Domain Group for $180 million in 2022. Following the sale, Frank is on a mission to raise $1 million for charity by publishing a cookbook called ‘Eat with Purpose’, where 100% of the proceeds will go to charity. Launching in October 2024, the cookbook will be designed to help high performing people learn how to cook fast, healthy and delicious food.
