If the rumours of an Anthropic acquisition are true, this makes a lot of sense. Anthropic are probably looking for a clean, high-signal dataset of metadata around business tasks that they can buy.
Until they finish evaluating competitors, and eventually migrate to .... something, they are completely stuck. Jira is at the heart of all of their workflows and they cannot and will not move to cloud. This was an Atlassian partner, but they got screwed over on that part as well.
