What is the Mina group?

Could you please explain to me what exactly the Mina group is? I've heard of it in relation to cryptocurrencies but I'm not quite sure what its functions are or how it operates within the finance world. Is it a company? An organization? Or something else? What are its main goals and objectives? How does it contribute to the broader cryptocurrency and finance ecosystem? Could you provide me with a brief overview of the Mina group and its significance in this rapidly evolving field?
