When is it the right time to kill a Life Time Deal offer for early SaaS?

Here's the scenario

I've been helping a fellow Indie Hacker grow his SaaS over the past couple months.

After launching the MVP in April, it was launched on a Life Time Deal marketplace...

The original thinking was to do so in order to validate the idea, get early users, and gather feedback from these users. It's been a success with over 200+ purchases of the LTD in a matter of a few months.

To date it's really been the only "acquisition channel" deployed

We're now moving towards executing on a plan to update the marketing/positioning based on all the feedback we've gathered and are starting to go after new traction/acquisition channels.

The BIG Question -> Does it make sense to kill the LTD now?

It's served it's purpose of validation/feedback and the $29 LTD (nearly half of which goes to the marketplace) isn't really moving the needle on rev.

Sort of the classic dilemma of:

1. Focus on growing the user count
2. Focus on growing RECURRING rev stream
3. If the LTD is bringing in users, should we let it ride and ALSO focus on new acquisition channels that generate recurring rev?

Curious what your thoughts are!
