We have developed our own inhouse tools, of course lots of people use open source like Hashcat or BTC Recover, but those have bugs and wont open all wallets.
Our company is a Swiss registered company and we have been around since 2017, so there you go, pretty much public company.
We also sponsor many conferences like BTC Last Vegas last month and now BTC Hong Kong in August.

It is good to hear that the tools to be used were developed by your organisation, which means you alone can be able to use it and no other person or third party can be able to access it. However, if you claim to have personally built the tool for such a function or purpose, does it mean it works on all wallets, including Bitcoin wallets, and irrespective of the chain on which the assets are kept or stored? I could see your organisation on the list of sponsors on the BitcoinAsia homepage. Well done for your benevolence.
