Gospeak is a free and open-source platform to help meetup organizers and speakers grow together.
On the organizer side, they can create a group (like a meetup group) and then manage their events, CFPs and even sponsors. Gospeak can publish a nice group page with the group details and history (events, talks, sponsors...).
On the speaker side, they can create some talks and submit them to existing CFPs in the platform in a few clicks. They can keep track of all their proposals and publish a nice page about them, containing their speaker history and their current talks. More Info »
Organizers can look at public talks and ask to the speaker for a proposal, this can be a very nice opportunity for groups to find speakers but also for speakers to have more opportunities.
Finally, Gospeak will also gather a list of external CFPs (like big conferences) so speakers can find them easily.
