[Promoted] Experiment: Post-purchase celebration for first-time SaaS buyers

Experiment summary

We believe that purchasing GitLab for the first time is a big deal - it should be recognized and celebrated

To verify that, we will replace the current banner confirmation with a larger splash page interaction with prompts to add users.

And we’ll measure the impact on post-purchase users added/growth.

Checklist

• Fill in the experiment summary and write more about the details of the experiment in the rest of the issue description. Some of these may be filled in through time (the "Result, learnings, next steps" section for example) but at least the experiment summary should be filled in right from the start.
• Add the label of the group:: that will work on this experiment (if known).
• Mention the Product Manager, Engineering Manager, and at least one Product Designer from the group that owns the part of the product that the experiment will affect.
• Fill in the values in the ICE score table ping other team members for the values you aren’t confident about (i.e. engineering should almost always fill out the ease section). Add the ~"ICE Score Needed" label to indicate that the score is incomplete.
• Replace the ~"ICE Score Needed" with an ICE low/medium/high score label once all values in the ICE table have been added.
• Mention the [at]gitlab-core-team team and ask for their feedback.
