Sustainable Venture Prize: The 2023 Winner

The Yale Center for Business and the Environment (CBEY) is delighted to announce the winner of the 2023 Sustainable Venture Prize.

The Sustainable Venture Prize, created in 2008, awards $25,000 to a promising student business venture that advances environmental sustainability. As part of Startup Yale, the Sustainable Venture Prize was held on Friday, March 31st, 2023 and the four teams pitched their businesses that advance sustainability.


  • Carbon Loop: Creates a circular economy by cheaply sequestering carbon at low-temperatures from industry and produces high-value byproducts
  • General Biological: Makes mass-market chemicals from sugar instead of oil
  • Karuna Foods: We make the world's first microbial protein-based dog food with the least carbon footprint, offering nourishment without any adverse effects
  • Tyree Tech: Convert CO2 from major emitters to high-value, carbon-negative products 

The teams pitched their ideas and answered questions from the judges. Following deliberations, the judges awarded General Biological the $25,000 prize. Carbon Loop won the Audience Choice Award of $2,000.  


The 2023 SVP Winner ($25,000)

General Biological

Abhinav Godavarthi, David Sozanski (YC '23), and Julian Rubinfien (YC '23) seek to make mass-market chemicals from sugar instead of oil. Their goal is to supplant petrochemistry and demonstrate that biology can be scaled as a technology - in other words, to catalyze the shift from industrial chemistry to industrial biology.

Carbon Loop

Harrison Meyer (YSE/SOM ‘24), Perry Bakas (SOM ‘24), Conor Rooney (Ph.D, Yale Chemistry) seek to create a circular economy by cheaply sequestering carbon at low-temperatures from industry and producing high-value byproducts. Their goal is to develop cheaper point source carbon capture and create high-value carbon products, a technology that is scalable across hard to decarbonize sectors.
