Frequently Asked Questions (FAQ)

  • Why sustainability?

    We believe that entrepreneurship will play a crucial role in reaching a net-zero CO2 world. We have already run the first entirely Sustainability focused program and also are implementing Sustainability principles in the batches that are focused on other verticals. We want to support sustainability-focused founders to make a difference!

  • What does the selection process look like?
    • After the submission of the application to the Dealum, the Scouting team evaluates the application for eligibility. It can take up to 2 weeks for us to get back to you after we have received your application.
    • If the application fits our criteria we might ask you additional questions and invite you to take part in the pitch day to present the business to Startup Wise Guys General partners and team members.
    • Pitch day is an internal event to evaluate the business idea and meet founders face to face, after the pitches SWG team decides how to proceed with the application. Decisions are: move forward with Due Diligence, offer Wise Guys Pre-accelerator program, reject or stay in touch until later.
    • Due diligence process includes: the Tech call, Managing Director call, Partner/ expert call, and the Deal call.
    • After the startup has successfully gone through the due diligence process they are invited to the Selection Bootcamp.
    • TOP 10-12 teams are selected to participate in the acceleration program.
  • What are the investment conditions?
    Receive a convertible investment up to €120,000 (with a program cost of €35,000) and an additional €250,000 as a follow-on opportunity. If you register a legal entity in Bilbao, there's a chance to secure an even higher investment of up to €200,000.
  • What are sustainability specific criteria the investment committee will be looking at?

    For the Sustainability program – we are also looking deeply into the impact aspect of the business:


    Definition of impact (problem understanding and theory of change).

    Evidence of impact (metrics design and measurement format).

    Is the impact operational (and aligned with the business model).

    Systemic impact (is there a probability that the solution can disrupt and transform the entire marketplace).

  • What can I expect from the program?

    Throughout the program, there are four main focus areas on which we are working to help you build and grow your startup: Company building, Sales and marketing, Fundraising and Pitching, and Product building.

    Work in these areas happens through intensive collaboration with almost 100 mentors at workshops, one-on-one sessions, and sprint weeks, as well as through a dedicated implementation time throughout the program.

  • Where is the program taking place?

    This is a hybrid accelerator program, where 80% of the program content will take place online, and 20% of the program will take place in person in Bilbao, Spain. The program consists of four modules, and during and modules 1 and 4, startups will have the opportunity to be present in Bilbao, Spain to attend live workshops, mentoring sessions, and meet other founders as well as members of the Startup Wise Guys team. If a relevant conference or networking opportunity in Europe coincides with the program, the startup participants may choose to travel together to attend. All teams are expected to send at least one founder to attend the onsite portions.  Each team can expect to spend between 2-3 weeks in total onsite.

  • What is the expected commitment? Will all the team members have to attend the program full-time?

    A full-time commitment is a requirement to participate in the program.



  • I have applied for the full-time acceleration program, but I got an invitation to join an online pre-acceleration program. What is the difference?

    The Scouting team evaluates each application and decides what program the startup is eligible for. If we see the potential in the project, but it is still a little too early for acceleration we invite the startup for the 8-week long pre-acceleration program, where we provide mentoring and support to help startups grow faster. After the Pre-acceleration the best teams might get invited to take part in the full-time Acceleration program.

    The acceleration program is a 5-month program and comes with an investment. The main criteria to be eligible for the equity-based program are:
    – a working MVP
    – at least 2 co-founders
    – initial traction. MRR/ revenues.

  • Are there any geographical restrictions on who can apply?

    No, there are no restrictions, but you have to take into account that the workshops, mentoring sessions, and other program activities will happen according to the EET time zone, so you might have to adapt to this schedule.

    Also, it’s a hybrid program with online and onsite modules, therefore, some parts of the program will happen onsite, and you’ll be expected to be there.
