Two companies reaching out at the same time, I would agree with you. But three seems outside the realm of possibility, or at least, probability.

There's no support for your claims. You know neither the probabilities involved nor the number of individuals contacted by these companies. You have no reason not to believe this isn't a coincidence.

edit: It's funny to receive downvotes for a statement so devoid of opinion and so obviously mathematically/statistically correct.

It would be easy to calculate for someone who - unlike me - remembers something from their stats / probability class(es).

Assume that all 3 companies reach out yearly. They each reach out during a randomly chosen week. What's the probability that they will all reach out in a 2-week span?

Yes _if_ you know the probability distributions, then it _would_ be easy to calculate. But you _don't_. You can't assume your way away from that.
