Buddhism and entrepreneurship
I require that we treat our team members with compassion, refraining
  from false speech (teamwork, marketing and sales), and avoid taking
  what is not given (intellectual property, competition, finance).


None of the above is uniquely Buddhist or even religious. Its just ordinary human ethics expected in any ethical workplace. There is no need to ever refer to "Buddhism". 


  Well-meaning members of my sangha remind me that this path is
  incommensurate with the living practice of Buddhism. Somewhere in my
  heart, I feel like I've never been living it more than right now. How
  can I reconcile this understanding?


There is nothing to reconcile. Most Westerners don't understand Buddhism very well. They have never studied the Buddhist teachings for laypeople and believe Buddhism only teaches the hardcore teachings for monks &amp; advanced yogis. 

For a lay person, earning a living is part of Buddhism; which includes carrying on a business. As long as the business is ethical, the Buddha in the Pali scriptures praised laypeople who are successful in carrying on a business. 


  Monks, a lay follower should not engage in five types of business. Which five? Business in weapons, business in human beings, business in
  meat, business in intoxicants, and business in poison.
  
  Vanijja Sutta
  
  
  
  And what is the bliss of having? There is the case where the son of a good family has wealth earned through his efforts &amp; enterprise, amassed through the strength of his arm, and piled up through the sweat of his brow, righteous wealth righteously gained. When he thinks, 'I have wealth earned through my efforts &amp; enterprise, amassed through the strength of my arm, and piled up through the sweat of my brow, righteous wealth righteously gained,' he experiences bliss, he experiences joy. This is called the bliss of having.
  
  Anana Sutta
  
  
  
  The wise and virtuous shine like a blazing fire. He who acquires his wealth in harmless ways like to a bee that honey gathers, riches mount
  up for him like ant hill's rapid growth.
  
  With wealth acquired this way, a layman fit for household life, in portions four divides his wealth: thus will he friendship win.
  
  One portion for his wants he uses, two portions on his business spends, the fourth for times of need he keeps.
  
  Sigalovada Sutta
