Developers don't like to pay for software libraries so it was an uphill battle. My co-founder (our "COO") moved on because he got a very lucrative offer. I wanted to buy out his 50% of the business, he asked for a 40x multiple of yearly revenue. (For context, online businesses usually go for 2-3x.) In this stalemate, I did not want to continue growing the business with him owning 50% of it. Now that revenue has, through years of inactivity, died down to essentially 0, he agreed to let me open source it.
