We're organizing at Algolia a meetup every 6 weeks that takes place during lunchtime. The event is for people interested in the tech ecosystem to attend talks about various topics. It's not specific to developers and you can attend even if you're not one!
The meetup is open to everyone, but because we have a limited hosting space, you need to book your seat.
Videos of the previous sessions can be found on Youtube (https://www.youtube.com/playlist?list=PLuHdbqhRgWHIosfqQ-9whwXzN5sgY7NAk).
