Ask HN: Should I join corporate accelerator?

Does anyone have any experience with big corporate accelerators? I am wondering should I join or not.

In the short term it would definitely accelerate the business as we could close first sales with them.

However, in the long term, I am not sure will they interfere with strategic planning and execution. E.g. Even though they would only own minority of the shares they might do pressure on us if we also start collaborating with their competitors?
