To learn more about SAFEs, read our explainer here.
First, navigate to the SAFE or convertible note you would like to convert. Select "Actions" in the top right and choose "Convert convertible."
If you are looking to convert several SAFEs or Convertible Notes, you can instead use the Actions button from the Cap table detailed view, and select "Convert Notes" to enter the bulk conversion.
Next, select the certificate that the SAFE or convertible notes will convert into. This will be the Preferred Stock certificate held by the issuer of the SAFE or convertible note after you raise a priced round.
Note that you can select preferred shares still in draft form, so they don't need to be on the cap table before converting the SAFE/note.
For convertible notes and SAFEs, input the amount outstanding on the agreement in the "Debt Cancelled" box.
Add the cancellation date, which should match the date that Preferred Stock was issued to the issuer of the SAFE or convertible note - in other words, the closing date of your priced round.
Finally, select the applicable "Cancellation Reason" and hit "Next".
Select "Convert SAFE" on the following screen and your cap table will be updated to reflect the conversion.
