Regardless, seriously, I don't think anybody paid any attention to them ever. I'm not even convinced they are a competitor from looking at what they do. Payments is a big space, lots of players fit into different parts of the value chain and/or target different customers. I'm speculating, but I'd guess their issues raising money came from bad messaging. They aren't clear about what they do. I'd guess VCs were confused about what they did and/or explicitly misunderstood it.
They even had an office you could _see_ from Stripe's. Right across Brannan.
