FAQ
Questions you might have
Is it really free?
Yes. The program is co-funded by the European Union and financed under the de minimis rule. Neither participants nor listeners pay a fee.
Do I need to know how to code?
No. You’ll build with AI tools such as Lovable, Bolt, Replit or Cursor. Basic digital skills and a willingness to experiment are enough.
I don’t have an idea yet. Can I join?
Yes. Come with a problem you want to solve, or simply the motivation to find one, and shape your idea as you build.
I’m not a founder. Can I join?
Yes. The program is open to anyone on a startup team, not only founders.
Our company is registered in the Vilnius region. Can we still join?
Yes. Join as a free listener, or move your company’s registered address outside the Vilnius region and join as an official participant team.
What does “de minimis” mean for my company?
If you join as an official participant team, the value of the training is recorded as de minimis aid to your company: small-scale State aid that EU rules allow up to €300,000 per company over three years. It costs you nothing.
Do I have to come to Klaipėda?
Some workshops are in person in Klaipėda and others are online. The schedule above shows which is which.
What language are the workshops in?
English.
Does Baltic Sandbox invest in participants?
