Ledger Leopard was founded by two visionaries, Jeroen van Megchelen and Johan Mastenbroek, who recognized the challenges faced by businesses in the current supply chain landscape. Frustrated by inefficiencies, lack of transparency, and a need for better identification and collaboration methods, they knew that something had to change.

That’s when they discovered the power of Web3 technology. They realized that by leveraging blockchain, self-sovereign identity, tokenization, and verifiable credentials, they could help businesses overcome these challenges and create a more secure, decentralized, and sustainable future.

With their extensive knowledge and experience in the field, Jeroen and Johan set out to establish Ledger Leopard, a company that specializes in Web3 development and consultancy. Their mission was to help businesses harness the power of this emerging technology to transform their operations and unlock new opportunities.


Since 2017, we’ve been helping both start-ups and established enterprises implement web3/blockchain solutions.
