Those tools are affordable until the company making the tool needs to start actually making a profit and they raise their prices or they decrease their LOS. Then the tools become an expensive risk and the price increases end up percolating into your own startup. If you raise prices to compensate, you'll affect your growth. That's how startups go under.
