*Subject to available funding

Step One: Register as a user.

Click here to register.

Step Two: Complete a startup profile or join an existing team.

After registration at a Regional site, log into that site, get started by clicking on the “Apply" or visit your Startup Dashboard to submit a new startup profile. At this point, you have the option to create a new startup profile, or join an existing startup. Please only join an existing startup if you are already a part of that team. Your startup profile will not be displayed publicly until the accelerator begins in May.

Step Three: Pay your application fee.

After creating your startup profile, click on the “Apply" button, or visit your Startup Dashboard and click “Submit". You will be prompted to pay the application fee before you start filling out the application itself. Please see the Dates and Fees section below for more details. Note that if you would like to preview the application questions and begin working on the application BEFORE submitting your payment, we have provided a downloadable version of the application in the Application Toolkit section below.

Step Four: Submit your completed application before the final deadline.

Although you can pay your application fee and start your application as early as you want to, you are allowed to edit it up until the final deadline of May 1. We recommend asking our team any application questions as early as possible, attending our Q&A sessions, and getting a mentor or advisor to review the application as early as possible to avoid a last-minute submission.
Please complete the application by visiting your Startup Dashboard, opening up your application, and clicking “Preview and Submit' at the bottom of the form. Make sure to review to make sure all of the details are correct, and then press the final “Submit" button at the bottom of the page.

Step Five: Receive judging feedback and acceptance decision.

After the final deadline of May 1st, you can expect to hear back from us in mid-May about whether or not you were accepted into the accelerator. Regardless of your acceptance decision, our panel of expert judges will review your application and provide you with valuable judging feedback.

Application Deadline and Fee

The application deadline for the 2016 program is May 1, 2016.  Some Regions may consider earlier admission so applying early is encouraged.

The application fee per company is: $150 (regular), $75 (through an affiliate), $50 (student).

*To qualify as a student, the team must have a full-time student as the Team Leader and at least half the team must be students.

Participation Fee

If you are accepted into the program, the fee for participation in the Cleantech Open is $1200 for up to two members participating per company. This covers several months' worth of training, mentoring, and event participation, including receptions and meals. Travel costs and other expenses will not be reimbursed.
Need-based scholarships are available on a case-by-case basis - scholarship applications will be distributed after acceptance into the accelerator.

2) Funding

At the time of application, your startup must have raised less than $1M from private third party funding and less than $5M from all other sources of funding (grants, family and friends, and your own pocket).

3) Team

You must have at least two members, and at least one team member must be a US resident, citizen, or legal alien (i.e. F1, H1 visas).

4) Location

You must have a physical US address and your team or company must have activities (such as sales or operations) based in the United States. You must apply within the United States region where the majority of your team works or is resident. If your team is equally distributed among two or more regions, you may select a region from among those where members of your team work or reside. Is your team too international? Try applying to the Global Ideas Competition instead.

5) Participation

At least one team member must actively engage with the accelerator by participating in meetings or events that are part of the program, and by submitting final deliverables before Final Judging. There are only two mandatory events at the regional level: 1) the West Coast/East Coast Academies (you can choose one) and 2) the Regional Final Judging event. If your team wins at the regional level, you are also required to attend the Global Forum.

6) Conflict of Interest

You MAY NOT apply if you are an accelerator volunteer, judge, expert, advisor, mentor, chair, regional director, or if you are in any other way involved with the organization or operation of the accelerator. Immediate family members of the aforementioned people are also ineligible.

You MAY apply if you are affiliated with the accelerator's sponsors and/or partners, as long as you or a family member are not directly involved in the operation of the Cleantech Open, as above.

If you are accepted as an entrepreneur or team participating in the Cleantech Open accelerator, individuals involved in the running of the Cleantech Open may advise or mentor you, within the rules of the accelerator, but such individuals may not take a direct interest in your company (such as an equity stake or a paid position) and may not participate as team members until after the Global Forum in the year of your participation.

For our organization, cleantech has a broad definition and encompasses a lot of different technology categories. In addition, startups who get into our program are often at very diverse stages of development. In other words, there is certainly no 'perfect' candidate for the accelerator.

When judges look at your application, they will be evaluating your entry on the following criteria:

  • Team Is the team promising and credible? Have gaps been identified clearly? Do they seem able to attract additional quality team members?
  • Technology Is the technology potentially disruptive? Does it demonstrate the potential for a sustainable competitive advantage?
  • Market Is the potential market size large enough for sustained business growth, and aligned with the expectations of possible funding sources?


The toolkit is a collection of documents, videos and external links to provide you some guidance before submitting your entry.
