Yep - they tried to build it twice I think. We were worried about that when we started, because we knew a partnership with them would be helpful. After working with them for a while now, I think it's clear they still believe in the opportunity.
In terms of why it didn't work out, I think there are two factors to consider:
1) it wasn't their flagship product 2) they had a capped market of support. In essence, they could only build a network of locations within their existing ecosystem, and despite that being large, it wouldn't be big enough to win the space.
I think a 3rd party is most likely to succeed here, because we can facilitate integrations with all of the POS providers, and build a really big network that way.
