I wondered the same thing after seeing a comment on here that linked to the company and to a news article indicating the event happened this past weekend. I got from the original submission that this was a past thing and the "happy ending" was that Billy failed. But that appears to not be the case as the events were so recent.
The "busy with morning meetings" Billy referred to in his email was him speaking about winning startup weekend at a local entrepreneur group, sans his team.
I think the camera shot is poor though, it probably wasn't that empty. I believe that it was found from twitter or instagram.
From the article: "These days Billy can still be found pitching our work at empty meeting rooms around the community"
Screenshots seem to be from the last few days
Did this happen last year? My apologies for the internet detective
