Evaluation process
Our selection process consists of three phases to assess and support promising ventures:
Phase 1: Initial Screening (Non-Confidential)
-
Applicants submit their pitch deck and complete a questionnaire. At this stage, we evaluate the opportunity based on impact, team strength, market potential, and unique value proposition.
-
A preliminary assessment is made regarding the potential fit with VITO. Selected ventures proceed to the next phase.
Phase 2: Pitch (Non-Confidential)
- Shortlisted applicants are invited for a 15-minute online pitch followed by a 15-minute Q&A session. This allows our team to better understand the opportunity and ask targeted questions.
-
Based on this session, a more detailed analysis is conducted, and successful ventures move on to the next phase.
Phase 3: In-Depth Assessment (Confidential)
- If necessary, a confidentiality agreement (NDA) is established to facilitate a deeper evaluation.
- This phase includes a due diligence process, assessing investment potential, sustainability impact, and the added value of a collaboration with VITO. Final approval is based on the overall strategic fit and potential for impactful innovation.
Successful applicants will be informed after each phase.
Frequently asked questions
Are you interested in the opportunities VITO4STARTERS can offer your start-up, but still have questions? Then you may find the answer on this page. If not, feel free to contact us at vito4starters@vito.be.

VITO has unique expertise and infrastructure. If you are selected, you get access to this through one of the following elements or a combination of them:
- Technological advice by VITO experts
- Building a proof-of-concept together with VITO experts
- Access to the VITO infrastructure (labs, pilot installations ...) to carry out experiments.
You will also gain access to the VITO network and VITO will ensure visibility and promotion on the VITO channels.
In the initial stages of the process (Phases 1 & 2), all evaluations are conducted on a non-confidential basis, meaning companies should only share information they are comfortable disclosing without an NDA. If an opportunity progresses to Phase 3, a Non-Disclosure Agreement (NDA) can be established to allow for deeper discussions and due diligence while ensuring confidentiality.
For additional security, all submitted materials are handled with care, and only the necessary team members have access to the information. We adhere to strict data protection policies to safeguard sensitive details.
