I remember first seeing Cleo way back when it was just the two founders (didn't they meet each other at some startup hackathon type event?) and they were rolling out cleo as a SMS based money assistant.
Looks like you guys shifted towards the Messenger platform. We (http://dispatch.pm/) looked in to the messenger platform but found it a bit restrictive for our purposes. How is it working out for you guys? Do you see yourselves sticking long term to messenger?
