We started developing Exbita in 2017 and being developing it for 6 years already and the development cost of it easily passed 500k.
500k in devlopment, what is the hourly rate in The country you are operating from?
You give astonishing little details away for a company which creates 500K Products.
In the era of remote work, I wonder how the hourly rate would be relevant as long as there is a standard available in the market today. Also, it's worth noting that OP did mention that they have been building the product for over 6years. It means they have had multiple upgrades to the product (maybe based on feedback from people that have actually tried out the product).
Well, it's one thing to buy the script that powers the trading engine, it's another thing to take this product and transform it into a working business.
