Every split works the same way

The founder picks the split, it is locked for the month, and it is shown on their page before you pay. Every tier is split the same way — paying more buys more access, never a different deal.

This is patronage, not an investment

Access and influence, never financial returns. No equity, no interest, no revenue share, no resale value.

Your country sets the VAT rate, which changes the net figure. We recalculate before you confirm.

What you get
  • Read every idea people have suggested, in full, including how each one would be measured.
  • Whatever the founder chooses to show beyond the public ranges.
  • Named on the results you paid for, if you want to be. Credit, not a claim on anything.

Payment is taken by the founder's own payment account, not by Thesis. You will finish on their page and come straight back.

Not taking payments yeta solo founder has not connected a payment account. The figures above are what it would cost when they do — we would rather show you the sum than put a button here that goes nowhere.

From €20 a month, for as many months as you choose to.

Recurring monthly until you cancel, charged on the day you start and on that date each month. Accounts are not open yet, so cancelling means replying to the founder's receipt — the money is taken by their payment provider, not by us. If they stop answering, your bank can revoke the mandate or reverse a charge without their agreement. The month in progress is not refunded.

If a founder has gone quiet and is not answering, you do not have to wait for them. The payment is a card or SEPA mandate on your own account: your bank can revoke the mandate or reverse a charge, and you do not need our permission or theirs to ask. We would rather tell you that than leave you waiting on somebody who has stopped replying.
