First, $12/pound is too expensive. Yes, I know you've got delivery and other costs, and it's best to start high. But know you'll need to reduce the price over time.
Second, consider pitching this to the keto market. Spinach + fat is a great keto item. It's really hard to order keto-friendly takeout. Might fill a niche.
We do have a keto-friendly variant (Classic Saag Paneer), and we'd love to make inroads into the keto market. Would to love to hear your thoughts on how we might do that -- feel free to email me at soham@pashi.com
I have no affiliation and I’ve never even heard of Sagg in my life, but it seems interesting.
On the other end, there's pouches available on Amazon for ~$24 for 60oz (6 10oz packets), which is about half the price, and also deliverable. Hard to say what attention to nutrient content might have been involved, but regardless, this is a good bet regarding how low the pricing can get.
