Big corporations often resist innovation because their internal “immune systems” attack disruptive ideas that threaten the status quo. Startups, however, thrive on disruption.
The comfort zone created by high, stable revenues, market dominance, and brand size can be quite limiting for big corporations when it comes to innovation. A traditional model creates a sense of safety, making many corporations unwilling to leave the comfort zone of old ways, with the mentality of "If it's not broken, don't fix it". Only in this case, "it is broken", and innovation must be viewed as an integral part of a company's survival, not a luxury.
That's a real thing - disruption is baked into startup DNA, but big orgs still default to protecting what they already have. Always wild to see how fast that internal pushback kicks in.
