All the inputs here are very helpful, and each contributes a different and important dimension to the picture. I would add that securing funding for a disruptive startup is MUCH more achievable with two co-founders than just a single founder. There is far too much work for a single individual, even if that person is working 100 hours/week. This is especially the case for a disruptive startup where the demands of understanding the market and developing the tech compound the challenges of fundraising. One of the things any potential investor will look at is whether the founding team is physically capable of doing all the work necessary to be successful. Two heads are better than one.

The idea pitch is not enough. You have to pitch idea traction. Unless you have started and sold start-ups before, the chance of getting funding just based off idea is very low. Demonstrate through customer discovery process that your product indeed has a potential in the market. Show that your clients want this startup to be build. This evidence will help you secure the funding.

It begins with your story told in a compelling manner. Reinforced by market data and initial traction elements. You should leverage your immediate network of the people that believe in you the most while simultaneously expanding your network with valuable connections. It is also important to present yourself as a domain authority in your space so make sure you are the expert! Pitch materials can range, but investors are always investing in the founder and the product-market fit! Pursue any and all potential funding paths and do not give up when you hit your first or second or third roadblock!
