Building a startup without investors?

I’m building a SaaS product (https://create.video) w/ 4 friends and currently all of us employed by tech companies. We all know how the tech industry works, what we should focus while building the product & we all made micro-products, but we can’t decide about investment. Here is the list of pros and cons and I’d like to hear more from you guys. ***Pros*** * We have complete control of our destiny. * We have the freedom to quickly change path as needed. * When there is little money, we will find most cost-effective solutions. * No stress from investors. * Without investors we will learn how to manage a company slowly while it’s growing ***Cons*** * The risk of losing business and personal assets. * We can use their network to grow quickly. * We can hire more people to make product bigger * We can put more budget to marketing And I’d like to hear more real-life stories from founders. Thanks!
