Often user researchers, even at large and prominent software companies are expected to create reports on their findings and present them once, that is the extent of their involvement with stakeholders.
These reports can often be dense and require a lot of effort from stakeholders to consume. They are also not well suited to Agile development environments.
Instead, I recommend taking a two-pronged approach, first, develop relationships with all key stakeholders across the organization, help them understand what UX research is and how it can help them attain their goals.
Second, put your findings in easy to consume slides that you present to small groups of stakeholders, so you can facilitate discussion and work through how your findings will translate to the product or service together, as a group.
Another key element to ensure that product decisions are based on real user feedback, is to evangelize results constantly in different internal forums. Some things to try are film screenings, sharing love and breakup letters at all-hands meetings, passing out UX research guides, and hosting workshops.
