Looks like TIPJAR is raising again. It seems to have doubled in valuation since the last raise and mentions in their pitch $45 billion is exchanged in tips in the US every year. Globally that sets up for a nice revenue opportunity, with the move to cashless societies.
I quite like that it appears to seemily integrate into different international markets. A struggle with other fintech companies. I guess only question is if or when something like this would ever go public or get acquired.
Would be intersting to see how previous investors are looking at this one
