It's not often you are presented with a vision of the future of online video in a pub in London.
He believes that the future of online video is not YouTube or even live video, he thinks it is video conversations among a community.
His Seesmic project is currently in Alpha - very early release - but already he has built up a strong, and loyal, community of so-called Seesmic-ers.
Here's an example of a video he made while we chatted.
Within minutes of posting the video to Seesmic, he had replies from the community all around the world, including from members sat around the corner in the same bar.
"YouTube is not a conversation," explained LeMeur. "As one Seesmic-er said to me, 'YouTube is about the videos, Seesmic is about the people in the videos'."
Users can record videos via webcams and upload directly to Seesmic, or record using YouTube and post from that site.
The company is also working on a mobile phone version of Seesmic.
He says Seesmic is more intimate because video allows users to see each other for who they are.
Users reply to each others' replies, creating an almost infinite threaded conversation around different topics.
Seesmic has an arrangement with micro-blogging site Twitter so that as soon as a new reply is posted, it is also posted on a user's Twitter page.
It's a great example of how two start-up companies are leveraging each others' success to strengthen their own platform's offering.
The death of Benazir Bhutto and the recent crash-landing of the British Airways plane at Heathrow had provoked much video chattering, says LeMeur.
"People are fed up of seeing the same footage on the mainstream networks. With Seesmic they can go in a different direction," he explains.
For LeMeur, Seesmic is not just a business and a social space, it's also where he has done business.
"Half of my development team I met on Seesmic," he explains.
He has $6m in funding and says he is in no hurry to start monetising the project. His backers include big names such as Skype founders Niklas Zennstrom and Janus Friis, LinkedIn founder Reid Hoffman, and people like Ron Conway, one of the original investors in Google.
LeMeur hopes that Seesmic will become THE platform for video conversations. There is an API that people can use to build on top of, in much the way Facebook is positioning itself as the lingua franca of social networking.
He admits that the thought of YouTube wading into the video conversation space is a risk.
"That's the challenge. That's the excitement of being small," he says.
LeMeur is due to meet YouTube co-founder Chad Hurley soon after he requested one of the sought-after invites to take part in the Seesmic trial.
But he says if YouTube came knocking, Seesmic would not be for sale.
LeMeur will be in Davos at the World Economic Forum next week. He is working with CNN who will use Seesmic-ers replies to questions posed by LeMeur on the channel as an experiment.
It will be a very high-profile public showing of Seesmic.
And something that is bound to keep investors happy.
