Who it's not for

We turn people away. Below is a list of exceptions; if you recognize yourself in even one point, don't pay.

01
You're looking for passive income or a second salary.
02
Venture would take up more than 50% of your net worth.
03
You’re a founder looking only for money. Membership is for those who invest; founders with a round, see “Investment focus”.
04
You need a certificate or a resume line.

FAQ
How is this different from a course or a deal platform?
A course ends, and a platform just lists deals. Here you pay for a group of people who invest their own money and for access to the deals that pass through that group. Education is part of the membership, not the product.
How much money do you need for this to make sense?
The subscription is €149 a month + VAT where applicable. To join Shark Tank you need a ticket from €3000, and we assume you plan to write at least 10 such checks over a few years.
Do you make money on the deals?
On the site you only pay for the subscription. Syndicate deals are structured separately, and we show the SPV terms before you declare a ticket.
What language does this run in?
Mostly Ukrainian. Sessions and chat are a mix of UA, RU and EN, depending on the speaker. We don't make it a problem or hide it.
Can I cancel my subscription?
Yes, at any time. Access continues until the end of the paid period; we don't refund unused days.
