What your trying is one approach to finding investors. Here's another that in my experience is far more effective. I'd tap your network, and it's probably actually a lot bigger than you think! Linkedin is the perfect tool for this. Look for people you're connected to, that you trust, and that are suited to helping your business (ideally in your industry, or experienced in fundraising, etc) and that have a good network themselves (ideally they're connected to some investors you're interested in, but not required). Reach out to them, and let them know you're starting a venture, and are looking for their advice, and would love to treat them to a 30 min coffee meeting. People love to hear that others think they're awesome and they love to give advice which makes them feel awesome, and this is someone you know, so chances are they'll accept. Send this request to everyone relevant in your network. At the meeting, tell them about your venture, give them your pitch, hear their comments and heed their feedback, and ask them for 3 people in their network that would be great people to talk to. Get intros to those people, and repeat. If you do this diligently and listen well, your network will expand extremely quickly, and you'll be able to get introduced to literally anyone you want. This is how our founding team at Tachyus acquired our first customer within 1 month of starting, and having no experience or direct connections in our industry.
I'm always down to chat in more detail if you're interested. Best of luck!
