As a data professional, I've got to admit I'm having difficulty differentiating your service from any of a number of other similar offerings like stitch or supermetrics.
You say you charge metered pricing but this information seems to be missing from your site, I understand it's hard to price a new product but I personally need to know pricing before I am able to recommend a product to a client – so the more available this information is the easier I can compare you to others.
I do like the SQL transforms, they don't replace DAG orchestration tools like Airflow but it's a very nice feature that covers a lot of what companies with basic data needs will want.
