Looking for hotspots where can start some networking with technical or programming people interested in starting a new venture (Not a platform; could be events or meetings)
I suggest just look up meet me app, it has global reach, and you are certain to find a group you can connect with
As with any major city, there are already collections of Meetups and small business groups that are currently being hosted in your city. No one can recommend the "best" for you because we have no way of knowing what criteria make its value high for your specific case. Use the tools that are available in any city. Go to Meetup.com, go to your the government's small business ministry, visit co-working spaces. It's quite certain you will find dozens of opportunities, along with ratings by participants that describe what the groups/meetings are like and characterizing them in ways that help you choose which are right for your needs.
