About ThankU

ThankU wants to revolutionize the way we say thank you: Giving thanks and doing good at the same time!

Through our platform you can give thanks to others by sending them a ThankU. The clou: by supporting a good cause you give your ThankU a special impact. With just a few clicks you can surprise people with a personal ThankU message and e.g. planting a tree as a thank you.

True to the motto "Do good and talk about it" you can collect sent and received ThankUs and share them with the world through a personalized ThankU wallet.

Give it a try and make someone happy!

The team behind ThankU

thxto gUG (thanku.social) was founded in June 2020 by Lukasz Belza, his brother-in-law Martin Belza and Dr. Carsten Emil Meyer as a non-profit enterprise and was realized without any outside capital. Currently the team works 100% on a voluntary basis — ThankU is our passion project and we want to contribute to a good cause with our work.

Lukasz Belza

Lukasz Belza

Founder / Managing Director

Lukasz had the idea for ThankU, because he himself was (and still is) repeatedly called by friends and colleagues with the question: Lukasz, I know you are a lawyer, and that is your job … but would it be ok if I could ask you 5 minutes privately a legal question? How nice it would be, Lukasz thought, if he could ask for money for these favors, but not for my own pocket, but to plant trees for example … and ThankU was born.

Lukasz is a start-up lawyer and lives in Berlin

Martin Belza

Co-Founder / Tech

Martin first heard about ThankU when he was on the phone with his brother-in-law Lukasz. Since then he is on board and on fire. As an all-rounder, he single-handedly programmed and designed the ThankU platform. This product is finally something really useful, something you like to work on with full enthusiasm says Martin, who has been realizing internet projects since the late nineties.
