Yes and no. That same inertia of the larger companies allows them to stay in business even after large missteps. Remember Lenovo built-in Superfish [0]? Amazon/Apple/Google are entrenched enough that can take risks, apologize, rollback, and wait for short term memory to pass and release the v2 under a different product name.

Across all startups, yes they can be risky and there will be innovative outliers that take off. But for a single no-name startup a misstep can be a death knell.
