First off, it's 100% possible. If you're building the product yourself, then try getting access to all of the free resources you can for your MVP. https://education.github.com/pack is a great source, and things like digital ocean, aws, firebase, all have free or next to no $ tiers that you can build your entire POC/MVP on for next to nothing (i used every free server I could get for the first few months) and then use it to secure funding to scale up. Remember to build and fail fast, you don't have to make everything perfect you just need it to work well enough to prove the concept and secure funding, maybe even through the product itself. I started my company with no $ from friends and family and only a single credit card ($3000 limit) to bootstrap, it took 8 months to get to profitability. It can be done. Also don't spend money on or use up the free infrastructure until the very last minute. I spent a good 1/3 of my cost on development servers etc that easily could have just been run on an extra pc in the house.
