If you have a way to surely differentiate bad deals from good deals, while keeping a low false negative rate (i.e. still being able to notice the next Airbnb/Google/etc...), I'm sure a lot of investors will want to talk to you.
No absolutely not I'm not an investor. I guess with hindsight it is easier to see how bad it would be. In the microISV space, having expenses below revenue is the only way to go, so it all feels really remote.
