I've heard a lot from the other side as well, technical people asking how to find the perfect business partner at a time when everyone has their own idea.
Ask yourself what qualities would a founder have to have that would make you give up your idea and join theirs. Then strive toward having those qualities.
In my perspective, if I see anyone hustling either by getting together a makeshift MVP or pre-selling to customers, then I know they have the drive to succeed.
Second best option: friends of friends
Last resort: some random developer who falls in love with your idea. Just don't sign any paperwork until 1-3 months after you start working together (if so, read https://medium.com/@colunchers/founder-vesting-c214e86c59b0).
When I met my programmer, we were actual in a startup coworking space, he looked stressed so I chatted to him a bit. He lost his iPad at the venue, so naturally I tried to help him look for it. We exchanged business cards and briefly chatted. Turns out the project that I was doing, was something that he always wanted to do - and, the added bonus, our apartments are within ten minutes driving distance. A perfect match.
On another note:
Does anyone have any suggestions to my team, we have a hustler, a growth hacker and a programmer. All of have strong connections and experience.
We lack in two specific areas: social media marketing/ management and graphic design. Would you look to adding on a 4th member to this team to take care of these roles? Any advice will be appreciated. We will be launching March next year.
It's very unlikely that you'll personally meet the right person, but actually fairly likely that someone you meet will know the right person. So just talk about your idea with everybody who will listen, get those business cards into people's pockets and see what the universe brings your way.
You'll wanna get facetime with "connectors" (if you've read the Tipping Point, you'll know what I mean). An email intro from one of them to the right person is all you need.
JSLA (www.js.la) is one of my favorites. NodeDTLA (meetup.com/NodeDTLA/) is great, and those guys recently spun off a new one: called techDTLA (meetup.com/techDTLA).
Joe Devon (@joedevon on twitter) is a good guy to know. He organizes CTO events in the area, and a PHP meetup (meetup.com/laphpdev).
There are also hackernews meetups, PM meetups, DBA meetups, undirected coding sessions, and lots of others.
Feel free to email me (my username @gmail) if you need anything.
