I’m using my savings to cover my family’s expenses, not to run the company. Sure, if I needed $100 to register an LLC or $200/month for a sever I’ll pay it from my savings, but I think my point still stands that it’s perfectly viable to work for yourself in tech without any outside capital.
Sure, having some savings definitely helps. If I had no savings, I would have probably left anyway and did consulting or a part-time job that would have allowed me to work for myself on the side. I couldn’t do that while working for Amazon.
