Which company is mantra?

Excuse me, I've heard of this company named Mantra being mentioned in some financial circles, but I'm not quite sure what it is. Could you possibly clarify for me? Is Mantra a fintech startup? Or perhaps it's an established financial services firm? Also, could you tell me what kind of services or products Mantra offers? Is it related to cryptocurrency trading, blockchain technology, or something else entirely? It would be great if you could give me a brief overview of what makes Mantra unique in the industry. Thank you in advance for your assistance.
