Best place to start a business in the US nowadays? I will not promote.

Best place to start a business in the US nowadays? I will not promote. Hello All, as titled, is it still Bay Area? I prefer places with opportunities to meet people but of low cost of living for trials and errors. Heard that Austin in Texas is prospering as well. I would also need to find ventures to support my start up. Thank you so much! I will not promote at all.
