GameCredits Inc, the people building this, started in 2016. The company however was small and entirely self funded, around 10 people. It has grown since then, very rapidly after the crowdsale since we needed to onboard new people to help with development of new applications and projects.
No one is funding our education with regards to coding. We hired and had developers capable of building the necessary applications. However, these are applications that have never existed. It can take months to build applications that have existed in some shape or form (think building some type of exchange). But we're building in-game wagering mechanisms that allow users to transfer value using smart contracts (another new technology). Development is rarely a cut and dry process, even with the best developers in the world.
And the technologies that we had prior to funding were our store and payment processor. We were able to get an intimate partnership with Unity specifically because of the existing store technology (a partnership that took months to establish).
