In standard HN/startup parlance, are you a potential CTO looking for a CEO co-founder? If so, there are doubtless plenty on here. Maybe search for "non-technical founder" or similar here, if you haven't done already.

If you're just looking for business ideas, people are notoriously reluctant to give those away - rightly or wongly :)

Edit: Perhaps put your contact details in your profile.

Edit 2: Definitely have a search, see https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...
