What Keeps You Going and Putting Money Into Your Product?

The first 75,000 we were looking at it as only an internal tool. We didn't think we'd make money on it. By the time we sold our first customer, we had about $700,000. And over that following four years is then where we put in another $600,000,. But you know, I was putting a lot of money into it. Could have not worked, right? A lot of SaaS products don't work out or, you know, it's, there's not a good niche or whatever it is. However, I had a gut feeling that it was going to work and where I poured everything I had into it.
