Let me play devil's advocate for a second. The short answer to your question is no, it's not possible in any reasonable sense to get funding today with zero connections.
You've admitted that you have no close friends who can be cofounders (ie. you're a loner), that you have no staff, and no paying customers.
Investors see all of those as red flags. They like multiple founders for many reasons, including social proof and free labor. The only thing you have going is presumably a working app, which does give you some initial credibility. They also expect a large-enough market, over $10 billion.
If you are in the social media space you will also need whatever the minimum subscriber base is today, around 5-10 million users to get funding.
Instead of chasing VCs with a bad story, you're better off finishing the next point release and devoting your time and energy to sales and marketing. And make some friends, ffs.
If you want to read sole-founder lore, then Marcus Friend (POF), Pierre Omidyar (eBay) and patio11 (hmm) are worth reading.
