Ask HN: Setup celery, built dashboard and website, but what to compute?

So I've built up an entire SaaS platform. There's a website, dashboard section where user can login and submit jobs, celery backend to queue jobs and process long running jobs, billing page where stripe handles payments and automatically updates their account.

So the car is ready to be driven but it's missing the driver. The driver being the value proposition. The jobs that will run on celery that ends up providing value to my users.

How did I end up in this situation, well I built up the whole infrastructure for a project which did not gain enough traction, so I'm trying to salvage the generic parts to launch another idea.

I would like some suggestions on what jobs I should be processing. Video transcoding? Plenty of SaaS based on that idea. NLP processing? Done.
