Jack's Stir Brew built its name on organic, fair-trade coffee and a patented brewing method since 2003. Founder Jack Mazzola stepped back in 2020, and investment firm Feenix Venture Partners now holds majority control after merging the chain with a wine bar business in 2022.
The Big Picture
Jack's Stir Brew built its reputation as a scrappy, organic, fair-trade coffee shop when it opened on West 10th Street in 2003. Founder Jack Mazzola stepped away from day-to-day operations in 2020, and New York investment firm Feenix Venture Partners became majority owner in 2022 after merging the chain with wine bar operator Vin Sur Vingt to form TenEleven Hospitality. The cafés still carry Jack's name, but the company now answers to an investment firm's multi-brand portfolio, not the founder who started it.
