interesting idea; I know prices for SaaS are hard to get right but somehow I find your pricepoint a bit too high because I feel most podcast uploaded to youtube always listen in the background
Unsurprising here because almost no one has a podcast and even among those who do indeed have a podcast very few have the problem of converting their podcasts to video. The way to find out if the price is a problem is to talk to potential customers. Which means talking to people with podcasts. Which means identifying podcasters and reaching out one at a time.
That's hard. But the feedback will be from people who might fork over money. Good luck.
