Not in our case, we love startups reaching profitability by just raising a seed round. It's most of the time the best way to confirm that the business model is right.
It's also easier to raise a big round after that, invest a lot and grow.
Okay, how do you suppose to exit then? I take $150K from you, create a small SaaS service a la @patio11 and then start slowly crank up customer base, showing stable 10-25% y/y growth. I see no exit for your 15%
