Why we don't use an ORM

So basically you built your own in house orm or alternative to orm using what you call repository objects . well done if it makes you win and makes your life easier.

Does it really matter whether you are using orm or repository objects provided you app is providing business value. Unfortunately, technology alone does not make an app win. So to my mind it doesn't matter whether you use a framework or not. It doesn't matter whether you use ORM or not. Just demonstrate business value to your would be customer.

I think a blog post focusing on the business value of your app will be better than any blog post on ORM bashing or rails bashing. How does anyone's use of ORM stop them from paying for your product. If it doesnt then don't alienate anyone from your customer base by trying to make what they are comfortable using to look bad. I think Stripe is using ruby but without any framework or orm but that is not the basis of their marketing communication.

If you can have a series of blog post on how to use the metrics you provide to make businesses look like consultant in the eyes of their customer, it might do you more good on the road to traction.
