Could try reaching out on Twitter to tech journalists. Or emailing some. Write this story yourself as if you were a journalist covering it (just don't write in 3rd person) and put it up on the company blog (or wherever). Link to that when pitching the story. Might sound counterintuitive but linking to an existing story makes it so much easier in my experience.
