When should I create a new Survey versus adding more slots to an existing one?

Rule of thumb

Add slots when you want more data from the same peer group.
Create a new Survey when you want a different peer group but under the same question model.

Example

If your Survey targets “Senior PMs at Series B SaaS companies” and responses are coming in quickly, add more slots to increase statistical weight.
If you want to compare “Senior PMs in Series C SaaS” or “Growth PMs in fintech,” create separate Surveys under the same Poll. You’ll be able to compare them side by side (group 1 vs group 2) but also view all results in one view -- the poll level -- where we compute statistics across all surveys in the same poll.

Adding slots to active Surveys

If you originally purchased 4 slots and later decide to expand, you can add more slots at any time while the Survey is open. Once a Survey closes, it cannot be reopened — adding slots after closure isn’t allowed.

To gather more data post-closure, create a new Survey under the same Poll. It will behave like any other new Survey: results release in safe batches of three or more responses.

When that extra survey closes, you'll be able to view its results on its own (like any other survey) but it will also be included in the poll-level view of all the surveys that have now closed under this poll

Why closed Surveys can’t be reopened

We release partial results only in safe batches of three or more responses. Small surveys show a limited preview at 3 (mean + median only), while larger surveys unlock in steps of three. If slots aren’t divisible by three, we skip the last “unsafe” unlock so the final batch is ≥3. This preserves anonymity and data integrity. You can read more about this in this article

For anti-triangulation reasons. Allowing a closed Survey to reopen for a single new response would effectively create a “Survey of 1,” violating our anonymity principles.
Keeping Surveys closed once completed ensures data integrity and protects Respondents.
