Sobotka Seed Prize for Sustainable Ventures

Innovate with a purpose. Start a venture that addresses the needs of both the market and the planet.

Sobotka Seed Stage Venture Grant: The 2018 Winners

This prize provides seed funding for start-up ventures in the field of business and the environment. The goal of the funding is to support students in creating competitive commercial enterprises that market viable products, services, and projects while tackling some key environmental problems.

We are looking for solutions in four key areas where science tells us there is an urgent need for action1:

  • Protecting and restoring ecosystems and biodiversity
  • Food, agriculture and land use
  • Energy use, efficiency and access
  • Materials and waste

$20,000 will be distributed between one or two ventures selected to receive the prize. 

We allow solutions at all stages of development that tackle these four areas of impact, as long as there is potential for impact and the idea is viable.

1We looked at three frameworks to identify these key areas of impact and action.

Funding opportunity

The Sobotka Prizes are for student ventures from departments across Yale University. Use of the proceeds is limited to one year and may cover expenses including, but not limited to equipment, analyses, data purchasing and surveying, business filing, and travel for faculty and students.

Application Requirements

The application must include:

  • Qualtrics online application
  • Excel-based budget
  • Team members’ resumes

Successful proposals should meet the following criteria:

  • Teams must include at least one current Yale student.

  • The business concept must be commercially viable and produce environmental benefits for society.

  • Ideas should fall within the four identified areas of impact.

  • Teams must not have previously won a Sobotka Prize (or, as the opportunity was previously known, a Sobotka Grant) or the Sustainable Venture Prize offered as part of Startup Yale.


The application for the 2023 Sobotka Prize is currently closed.


Applicants will be notified by the end of the semester whether or not they have been awarded a prize. These are competitive prizes that will be evaluated and selected by a committee of professionals and experts. Proposals will be evaluated for the following:

  • Viability: Does the venture have commercial viability? Is the idea financially and operationally sustainable? Does the theory of change make sense?
  • Opportunity: Is there a need for the proposed solution and will customers pay for it? Is there sufficient demand/opportunity in the market? Does it have a competitive advantage with differentiation and address barriers to entry/exit?
  • Team: Does the team composition include knowledge, skills, passion, energy and ability to execute?
  • Environmental impact: What is the potential to contribute environmental benefits to society? What are the negative impacts and how does the team plan to address them?
  • Financials: Do the assumptions in the financial plan reflect what's needed to execute? Are they in the ballpark of realism? Is there appropriate spending in the right areas? Is the proposed use of proceeds a sensible path to advance the venture?
  • Succinctness: Clarity and quality of grant application

The winning student ventures are required to acknowledge, where relevant, support from the Sobotka Prize.

Past Recipients

Over the years, the Sobotka Seed Stage Grant program has supported many start-up sustainable business ventures.  Read the stories about past recipients and how this grant impacted the trajectory of their ideas. 


1. Can my business idea be an international venture and not necessarily within the USA?

Absolutely, your venture can be anywhere globally provided it has an environmentally beneficial impact.

2. What are my chances of winning?

Every application is considered holistically and has an equal and fair opportunity to win. Historically we have received between 10-20 applications per year.

3. Does it matter where in the process I am?

It doesn't matter if your venture is in the Ideation, Pursuing, or Executing stage. Successful applications have come from each of those stages. What is most important is that the application demonstrates the viability of the idea, the potential impact, and the capability of the team to execute it.

4. Is the Sobotka Prize more for environmental or social business ventures?

Environmental impact is a requirement for the application. However, if your venture has a predominately positive social impact and a minor environmental impact, then we still encourage you to apply as we consider these applications seriously.

5. Can I use Prize funds to pay retroactive costs?

No, the Sobotka Prize cannot be used to fund costs already incurred.

6. Can I apply for the Sobotka Prize if I’ve already won another CBEY grant (Climate Innovation Grant, Sobotka, Sustainable Venture Prize)?

No, you cannot apply for the Prize if you’ve won the Sobotka Grant or the Sustainable Venture Prize. You are still eligible if you’ve won the Climate Innovation Grants.

7. My project is commercializing a faculty led research project, can I apply?

No, projects of this nature are ineligible for the Sobotka Prize. All projects must be Yale student led.
