Starting software mastermind groups

I'm looking to start some software mastermind groups. They'll function similar to startup masterminds, but with a focus on tech instead of business.

Format will be someone (e.g. a bootstrap founder) presents the design/architecture for their product and asks the group for help with a problem (or even general feedback). We then brainstorm and riff on the problem with the presenter for an hour or so.

Let me know if you're interested in participating! I have enough people to schedule one group, but I'd like to start multiple groups going.
