The one that seems to offer the widest reach is called newswire, and I feel like it’s no coincidence that they show up at the top of google searches and have a pretty high rating. They offer a money back guarantee, as well (I’m sure there are terms to this), so the risk is minimal.
I’ve heard of, but never used, one called Hype that is supposedly free. As we all know, nothing on the internet is truly “free,” and I still believe that companies that can afford it should pay for quality. That being said, our startup might be able to benefit from their service. Once our press release is prepared, I think I’ll give it a go and see what happens.
