Also, what is the revenue model behind Dagster? Will there e.g. be paid addons or paid support options? Does Elementetl have enough funding to continue development of Dagster in the long term?

Elementl is a venture-backed firm with several years of runway. Although we do not currently have a commercial offering, our goal is to make Elementl is successful, sustainable business. We have no stated public timeline for our commercial offering, but there will be one.

so basically further development of Dagster is secured for a good while?

Yes
